A Look at the Numbers…

Late September and Mia and I squeezed in one last scratch flight off of Chelan Butte during the "Fly and Bike”, one last swim in Lake Chelan. While the embers of the basin’s late season fires smolder out,the season is over. We’ve de-rigged the rig and dragged everything home for winter.

Just for the heck of it, I had a look at some numbers…

The tow rig burned 386 liters of fuel (84 Imperial gallons)  and logged 1972 Kms (1225 miles). This included a 1000kms getting the rig over the Cascades and back. My best guess, close to 600 kms of actual runs up and down the tow road !

So what did that get us?

Our core group of pilots (Mia, Mike, Randy and myself) logged 42 flights, 170 hours and 5000+ Km’s  of Cross country flying.  We picked our days carefully and left plenty of flyable days un-flown, choosing to “go to the beach”… after all, we do like our quality over quantity! Guests also contributed over 500kms more of XC, a very nice season indeed.

Mike sent me this GoPro shot from his last flight of the towing season. Its a shot of final glide into Mansfield. I believe it is a fitting shot to close our 2012 towing season. Looking forward to next year…..

Wake Turbulence

Frequently in central Washington we share the air with some pretty large aircraft. Military jets, Boeing out for a “test drive”, sailplanes, ultra-lights and so on. Of particular interest to me is the occasional “Heavy”. Boeing often test out variants of the 747 and in recent years The Boeing Dreamliner (787). On my last flight I had a 787 cross my course line and I was faced with trying to remember what a safe separation is for wake turbulence. (Been a very long time since I looked at my “From the Ground Up” training manual.

I found the following interesting training manual from the FAA:

http://www.faa.gov/training_testing/training/media/wake/04SEC2.PDF

In it I found the following:

“2.4.4 Vertical Motion of the Wake
The wake of an aircraft has behavioral characteristics which can help the pilot visualize the
wake location and thereby take avoidance
precautions.  The initial descent rate of the
wake is adequately described by classical
theory; the descent rate is determined by the
weight, flight speed and wingspan of the generating aircraft.  Generally, vortices descend
at the initial rate of about 300 to 500 feet per
minute for about 30 seconds.  The descent rate
decreases and eventually approaches zero at
between 500 and 900 feet below the flightpath.
Flying at or above the flightpath provides the
best method for avoidance.  Maintaining a
vertical separation of at least 1000 feet  when
crossing below the preceding aircraft may be
considered safe.”

Not a bad idea to glance through this article if you share the air with the big boys….

Icing on the Cake (season)…..

Overnight the NOAA Spokane soaring forecast perked right up (top of lift 10,000…. 500fpm climbs). The plans for a day at lake Chelan changed. My drooling over the soaring data caused Mia to give the old man one more opportunity to extract a few more K’ms out of the Columbia basin…. she agreed to run the rig! (I was wondering if this was going to cost me another bottle of Johnny Walker Blue?)

Like the “Flash” I had the glider loaded and by 11:30 we headed out (an early start). Along with a dramatically improved soaring forecast we saw cumulous development over the flats….. things where looking up!

It was NE at the tow site. Dang… a short low tow? To improve my odds, we moved the setup 2 miles further south to newly cut crop. Sure enough, 12:30,  2100ft agl tow, released into some nice smooth 200… then 300fpm up, let the games begin!

The first plan, establish wind direction. Looked to be a 6-12mph NW? … so it was a quick run to Wilson Creek, classic glides punctuated with well placed climbs between 8500 and 9500ft asl.  From Wilson creek I decided to tack on a little extra OLC distance by continuing on to the Hutterite community to the SE, climbed out and turn North East to Sherman (near Wilbur).

The run NE was also classic but the Q’s were not as well defined and would often just disappear… or appear randomly. East of Wilbur, I was having to work to find lift. Winds had switched more westerly and climbs stopped being reliable. I bailed on the Sherman turn-point and turned in the direction of L-Road.  At nearly 3 hours and 110kms into the flight, I knew this late season flight had potential to come of the rails… sure enough it did. 

NW of Wilbur I had one last climb that was the highest of the day just over 10,000ft asl (forecast was dead on!), after that everything ground to a crawl. Good dust devils no longer marked strong lift, short climbs, needed longer and longer glides. At this point, Mia joined up as my ground support (driving up from Almira , NE to the Highland silo landmark). From here she encouraged me to press on. The further west I pressed the lower the climbs topped out. By now it was a luxury to get over 7000ft. Once I was  as low as 3900ft asl (1500agl).  Looming ahead…Banks Lake.

Mia kept up the encouragement, I kept up digging up scraps to stay aloft, all while Mia waited at the exact field I had landed the day before.  One last climb to 6100ft asl, right near the edge of the lake. From here it would be at least a 12km glide  (and only 3500 agl to work with). This would of course not only include the lake crossing but to also reach a good LZ. Inspired by Mia’s previous day crossing of 5600ft asl (at the east side edge) and slender weak looking dust devil under the power lines on the West side SE of Mold cemetery, I went “for it”.

Of course I had to show off, I was even lower then Mia's flight, starting out on the east side at 5200ft asl (now only 2700ft over and still 10km’s to travel).  Fortunately, the tactic of getting to the West side of the lake paid off. With a very light NW surface the weak lift seemed to break with a little more strength over the cliffs on the west side of the lake and I was able to re-establish some improvement in my gains. One weak thermal on the edge to 6700ft agl let me push on NW, One more glass smooth 200fpm up allowed me to get over 7700 and suddenly, my glide to goal numbers turned in my favour! At 14km’s out I went on final glider to arrive at L+13 1800 ft agl. And that was it, not an inch of air was moving up, the day was done.

With a few tips about landing in the back of my head (from Andy Long, ATOS guru landing expert) and  Mia (the worlds best grounds crew and  a great pilot to boot) now at goal with a limp wind sock and kicking dust, stall alarm set,  I pulled off one of my nicest no wind landings ever (thanks to both Andy and Mia!)

6 hour, 180km FAI Triangle

Undoubtedly one of the nicest September long weekends in years. This last flight was the “Icing on the Cake” for this years season. In the distance we could hear the lonesome howl of some local coyote's, the sun was setting , Mia and I with bottles of Becks in hand took out the lawn chairs and enjoyed the last few moments of season (taking the glider down had to wait). This is a spectacular place to fly !

Just Another Day in Paradise

After Mike’s epic flight yesterday, he volunteered to drive the rig and Mia and I had the opportunity to get a little airtime. 

Soaring numbers where not bad, looked to be some west wind so I thought I would try and duplicate Mikes flight.  Lots of dust devils at the tow site with the winds switching from West to East and a little bit of North to allow a tow.

I was up first, Pinning off after a 1300ft agl north tow in some 500 up over L+13. The lift wandered off someplace (or I did) at around 3900ft asl. No panic as a good looking dust devil was brewing just SE of me. I did not quite take into account the heavy sink getting between A + B so I was happy to find some smooth lift at 1000ft agl and was able to work my way gently over to the real core as…. as “I got up to a good altitude to deploy?”. Truth is, dust devils at this time of year look much more intimidating then they truly are. Lots of bark but very little bite, guess it the fact the soil is as “dry” as it gets and sun is not quite as powerful as mid summer, this generates plenty of dust but not the power of the mid summer spectacles that deserve so much respect. Eventually I peaked out at 7500+ft asl and pushed south. In the meantime, winds delayed Mia getting on the tow rig (strong cross).  Mia was up and away (after a low save) as I reached Dry Falls heading to Wilson creek.

We had started off with a band of high cloud many miles to the NW but it soon became obvious that it was coming our way. By the time Mia had pushed a low easterly crossing of Banks Lake and I was heading north to Wilbur the high cloud started to become a factor. Mia managed to miss most of it by heading south toward Wilson Creek but I drove into the darkest of the shadow when I arrived in Wilbur. Soft lift was not going to be getting any better with high cloud cutting off the sun.

High cloud, taken by Mike in Hartline (note the Mammas cloud nested in the middle) :

P1040291

Mia saw that things might get challenging and started working her way back to the lake and heading home. At one point as I struggled low near Almira I thought she had landed? Turns out she climbed out in a smooth 900 fpm having managed to escape the effects of the high cloud.  Eventually I cleared the shadowed area and was pushing NW but the ground was now being “scrubbed” by a stiff north breeze and only the strongest lift was breaking free.  Mia got one last gain and pressed west to Mold across Banks Lake. I on the other hand, could not find that last needed gain and landed in a nice smooth LZ picked out by our expert ground crew (wind sock, dirt kicking, cut field…. that Mike… what a pro….. what the hell he drank all the beer?)  In the mean time Mia had crossed but ran into the same decaying lift and was forced to land in a good Northerly breeze NW of Mold (perfect cut field).

Mia's 75km flat triangle, My 134km FAI (150 km attempt)

With a little bit of sadness our Mansfield season appears to have come to an end, soon it will be back to work and the grind of “life”. Mike, Mia and myself, tipped a couple Becks, chowed down on a big feed of pasta (boy can Mike put away the pasta!).

Till next year… maybe?

Guests…

Mia and I decided to sit out a day to accommodate some guests. Fiona Katay, a Canadian pilot visiting Chelan came out with our old friend Jeff Kohler (who live in McNeil Canyon near Chelan)  By rights, it would be completely unethical for us to tow Fiona as she had once flown for the enemy… the dreaded Alberta Rocky Mountain Hang Gliding League (nemesis of the West Coast Soaring Club)… she seemed nice enough… (besides Mia told me to be nice, so I did what I was told). Right away, like a typical Albertan, she pushed her way to the front of the line and took the first tow (just kidding… the men where too fat to stay up in the light air… so they made her go first). 

With plenty of dust devils and a light north wind, Fiona and her Light Speed S where up and away (she dug out a nice save near the start point on L-Road) 

P1000797

 

Jeff soon followed on his 160 U2, by this time winds had shifted south so from the mid point setup we did a quick back track and set up for a south tow. Jeff got smacked a bit right on the end of the tow with good old flat land turbulence, but after a bit wandering about, caught a core and headed out.

Last, Mike yanked up south for a longer then normal and poor climbs just so he could perfect his low save technique (always the show off). Three tows, three away and the towline and chute recovered perfectly back to the rig each time = a good start to the day!

Towing, L-Road Mansfield WA, 09/02/2012

There didn’t seem to be any real set plan as our adventures head out into the wilds of central Washington. Nobody was really getting that high but a light westerly pushed everybody in the direction of Banks Lake , so Mike charged off with his VR in the direction of Wilson Creek. Fiona (with a vague understanding of the local landmarks) headed east with Jeff.  Jeff landed near Hartline,(30kms out)  Fiona made it to Creston but turn back to land near Wilbur (90km). With Mike still in the air after turning short of Wilson Creek and everybody else loaded in the Suzi we began to follow Mike slowly west. He was doing well after turning at Wilbur, but frankly I surprised he managed to stay up after 5pm! The little show off managed to not only make it back to the tow site he pushed on for a bit of tour and ended up Flying a 151km triangle.  We arrived back in Mansfield (after picking up groceries in Coulee City) Just a few moments after he landed. Unbelievably late for this time of year (near 7pm) leaving the boy breaking down in the dark on the front lawn.  He later hurt himself trying to fit his big fat head into the glider hanger (too big to get through the door?). Dinner feast and smiles all around.

Still giving just a little more….

Ok, perhaps a little early for the demise of the season. Yesterday we did our first “Billy Burger Run”.  Our west tow road (School House) just north east of town was the start point with pretty good cycles from the west.  Mike was up first and I was blessed with Mia’s offer to test fly her VQ! (Mia decided to run the rig).

With a fresh west wind in both the forecast and reality we moved our towing operation to the seldom used School House Road, 2 miles ENE of town. Its a nice tow road but a little short (2 miles).

Devils were popping all around the area so I sent Mike to go find me some lift. He pinned off after a two mile tow and gradually climbed away and headed west (into a west wind!…. I’ve taught him well?) Not getting very high but encouraging for my flight.

Now… just a small list of challenges that started with my first flight on the VQ:

-broken shoelace (don’t you just hate that?) field mod and fixed.

-Radio not working (moved off frequency… and locked?) fixed.

-Lost my airspeed probe walking to the truck! (seems to be a problem with flying the VQ …. see previous posts Winking smile )

-I then had to unclip to find my spare probe. (stashed in the nose) got my riser twisted when I clipped back in. fixed.

-Start the tow… Vario is awful quite…. sound is off. fixed in the air.

-Vario starts to fall down on its pivot… had to re-engineer the bracket after release. fixed

Top quality pre flight?

So, after all that… how does the VQ fly? I will write a full report later but for now it totally blew me away for how light and fast it rolled and handled. Once I got in the air I called Mike (who was struggling near Withrow) that it looked like a good day for a down wind dash to Wilbur airport and dinner at Billy Burgers (Ye old classic American dinning establishment…. a burger joint).  I came up 30 ft short of 10,000ft, just couldn’t get there. Both Mike and I had some challenging wild air landing at the airport but all ended well. (The VQ lands sweet… as Mia nervously watched me land in the bouncy air)

Billy Berger’s to Park Lake for a quick dip (just before the sun went down) and back to Mansfield. The season ain’t over yet! (looks like we are flying today again)

XC season slides away….

(The Labour Day Long Weekend) We get accustom to how great the flats of central Washington can be, its sad when mother nature hangs up the “Closed for the Season” sign. I’m sure there will be plenty of days before the snow fly’s that will be wonderful for XC but loosing close to 4 minutes of daylight per day rapidly begins to suck the life out of the suns ability to produce the classic conditions that make this place perform.

Ok, The good… yesterday, got the lawns all trimmed up then off to a fantastic day at lake Chelan. Crystal blue water, perfect temperatures. The kind of stuff that regular “tourists” do.  The bad?… (the image above), The Jet stream is writhing around like a demented snake. Parked right overtop of us and dragging its winds into the lower atmosphere. Not so much that the wind is the issue, more the inability for the sun to heat the ground when it is being scrubbed by the cool breezes that are present when the Jet Stream comes to town. 

Looks like the trend will stay through the whole weekend. 

Randy and a crew of other Hang Glider pilots have headed up to Cache Creek / Savona and might fair better as they could get the chance to sit in the “eye” of the weather pattern. In Mansfield we will hope that the forecasts are wrong and the winds die down to let the sun do its job….. If not, It’s GREAT swimming weather!

Humming bird fuels up for the trip south?

Boycott Apple….(or just become an Apple robot?)

When is big… too big?  When wiping sweat off your forehead constitutes a “swiping motion”… patents held by Apple.

Apple just recently won a Billion Dollar judgment against Samsung in a US court  and it made me think about way back when Apple was trying to win your hearts and asked you to embrace the “under-dog” Mac, they ran this ad:

“Iffy and Scratchy” (part 2)

Sticking with the theme “More Blue”, August 12th held more mystery as to if we would continue to see blue but strong conditions.

After my 6 hour pig out the day before I decided to take over the “Tow-Meister” duties and try to help Mia, Randy and Mike get some “end of the Encampment” airtime. Randy was all enthusiastic about trying to do his first 100 “mile” triangle (161km). Well not totally trusting all of the various soaring forecasts it did look like a day to stay on the upper plateau, nearly all the numbers looked poor down toward yesterdays first turn-point Wilson Creek.

Today we started a little further north at L+13, giving us plenty of tow road to get pilots high to try and connect. Mike was first up and pretty much mirrored what I did the day before (except the early pin off). After some very impressive scratching (didn’t know a VR could bank that steep!) he was up and away. 25 minutes later, Mia was up and away and before 1pm climbed straight up over 10,000ft asl. Another 25 minutes later Randy was up on the rig for what was going to be the longest tow of the day. Starting at L+13 we towed all he way down to L+7….. a 6 mile tow! In fairness to Randy, I could tell the tow was in real sinking air. Right at the end of the tow he connected and also climbed to over 10,000ft asl… Three tows + Three away = a happy “Tow-Meister” !

The plan for the group was to turn at Dry Falls but the air (as usual) over Saint Andrews  was slowing the children down. Pretty sure Mike was having trouble cuz he had nobody to hold his hand Winking smile 

While I back tracked to Mansfield to drop off the tow rig and head out on ground support with the Suzuki for chase, I heard complaints of rough air, scratchy broke thermals. In the end, the only pilot to do Dry Falls was Randy. Mia and Mike, turned nearby and soon everybody was heading west in the order that they launched.

On the ground it was hot as hell but I faithfully monitored the progress. When it appeared everybody was going to make it west of Farmer, I moved onto the Waterville airport… that is, after a short trip into Waterville to get the one of the best Espresso Shakes on the planet Highway 2 Brew Espresso!  A MUST stop for any ground crew.

Enjoying my “shake” out of the East end of the Waterville airport, my flight team all seemed a little concern about the time of day as they poked around their intended course so by now everybody had truncated their plans and was heading out with Mike having turned NW of Waterville, Mia over the east end of the airport and Randy just a few miles east of that.  From there everybody was dashing north in a bit of a tail wind and I had trouble keeping up. Just like yesterday, the visablity was not that great, no clouds to chase and few if any devils on this northern leg. Still, everybody was staying up high and cool… I finally relented and started to run the air conditioner (97f on the ground).

Mike made his next turn, south of the Wells Dam fire line, Mia and Randy crossed paths near Mud Springs but everybody continued to stay high. From here, Mike and Randy closed their triangles near L+13, Mia drifted a little further north short of Pearl Hill, down to Leahy Cut off. From there, everybody was heading for Mansfield.  With the LZ showing an ever so slight NE wind, Mike was first in with another perfect landing, Randy second with…. well a not so perfect landing (but no damage to anything but his pride… and got to taste a new flavour of regional dirt), and Mia…. always trying to be different, decided to land on the south side of the highway and dropped in for a nose up landing (not quite on her feet, the grass was taller then she expected).

Being the gentleman that I am… I carried Mia’s light weight VQ back to the house, while Randy and Mike carried their own.  Back on the lawn, they set to work emptying the cooler of cold Becks and consumed some leftover pasta from the night before… and all with smiles on their faces. Nice to see.  Shortly after, Randy and Mike packed up and headed for home. Mia and I where staying to end our trip on the 13th (no flying as it was forecast to be windy).

“Iffy and Scratchy”… (part 1 )

On Friday the 10th, Mike sends me an Email asking if it was worth driving over from Spokane to go flying. Pondering the blue hazy conditions that Randy flew in on the same day and the multiple forecasts that ranged from “Sucks” to “Epic” and the fact it was August, high pressure, no wind…. I replied back “my guess is its going to be “iffy and scratchy”…..

Saturday the 11th, the next message was 8am from Mike he was on the way (the boy is ga-ga to fly). Today Randy would serve his day at the wheel running the rig. Mia had her radio sorted (an unusual problem with her IC70, would receive for close proximity tests but could not pick up a transmission from more then a 100 yards away) so she was ready to fly. With our holidays nearly over, yours truly was also ready to get some airtime, even if it looked to be “Iffy and Scratchy”. Mike pulled in at 11am having already left his glider at L-Road midpoint (strong morning North eastern  winds).

By the time we were set up, conditions had turned light enough (north winds subsided) and we were able to perform the preferable and longer south tow.  It was to be a teaching moment for Randy, shortly into the roll I get the “Thumbs up” from the cab…. well below the airspeed indicators take off speed! Fortunately I was ready for what ever procedural anomalies a newbie tow operator could give me so I waited until I hit take off speed (an additional 10 mph) then released. While climbing I got on the radio and indicated that it would be a better idea to give the thumbs up when we actually achieved take-off speed Winking smile (a lesson learned)

I pinned off low (not really sure what inspired me to do so) at around 1200ft AGL. I promptly had to set to work scratching to save the flight. Dumb luck allowed me to blunder into so good air and I was up and away. Mike followed shortly after and was 20 min behind (very good turn around time for Randy and his first day back on the rig in over a year). Mike took a much higher tow and set himself up to chase me for the rest of the day. Mia, being last and was 30 minutes behind Mike. Randy = 3 Tows = 3 Away… nice start to his towing duties…

I was more or less leading todays plans and I was leaning heavily toward staying “on-top” and not heading east. The lack of Q’s, the hot hazy looking day was just not that inspirational. Thing is, it did not take long to realize that “looks” was deceiving and climbs up over 9000ft asl seemed easy enough so after reaching Dry Falls to the SE and at the last minute, I radioed back to Mike and asked if he would mind giving Wilson Creek a try (45km’s SE from our start)…. he figured why not so I headed across the South end of Banks Lake to nail some terrific lift just south of Coulee City.  The day was obviously way better then it looked!

Both Mike and I turned at the Wilson Creek Airport and headed for Wilbur Airport. There were a few slow spots and some epic nasty air on top but half way to Wilbur and we were establishing some wonderful climbs to 11,000ft asl. Meanwhile Mia had joined the leg to Wilson creek but being a little slower and not quite trusting the day turn early and started her leg up to Almira. As Mia reached Almira, Mike (still in hot pursuit…. and hanging close behind like a bad smell…) and I had pushed past Wilbur another 15km’s and turned west at Sherman (NE of Wilbur). It was around her Mike started gloating about cracking 12,000ft asl…. I pointed out the day was getting late and getting a little unpredictable and he best put the hammer down and start heading back for home on the high ground.  I was pushing fast to the west (and getting low). Mike said he was a mile behind and suggested that I could turn back and climb in some good lift that he had found. I muttered under my breath…”I never turn back”… and pressed on very low to a dust devil save. At which point he passed me….  At 11,300ft asl I peered to the west and saw Mike working some weak looking dust devils near the east edge of banks lake, so again I pointed west cursing the fact I let the young punk get ahead of me.

Right about now, Mia announced that she was crossing Banks from 7900ft  on the east side and heading to Mold over on the west side. As I arrived at the edge, I was down to 7300ft asl…. At first I thought Mike had already crossed? Nope… doofus was still poking around a mile behind me trying to get some height! I reminded him about his flight last year where he got stuck and ended up trapped., unable to cross Banks lake…he relented his search and at 7700ft asl started chasing me again. We all ended up low on the west side of the lake.  I got the award for lowest save, 3800 ft (1300ft agl?), Mia started her save from 4900ft asl, Mike being a lazy sod, felt no reason work for his airtime worked his save from around 5600ft asl (with Randy in the chase vehicle directly below him trying to break off a thermal… must have slipped him an extra $20 for the tow?

After all our hard work, we were all rewarded to a “glass-off”. Mia got the altitude she needed to head back to the house in Mansfield. I lazily enjoyed a climb at Sims Corner that eventually peaked out at 12,500ft asl and did a brief trip to the edge of Dyer hill and back to town. Mike did much the same…. except having no respect for his elders…. pushed an extra two kilometers to beat my OLC points for the day. Randy guided us all in with a radio and windsock (light and vacuum, always a challenge). Mia and I both with mediocre landings, Mike showing off with a perfect landing (little snot).

A short taxi from our LZ to the house and it was cold beer for all:

Flying at last….

August 10th, Randy and Mia head out to the tow site and its Hot and Blue!… well sort of…

A strategically narrow band of high cloud was going to put the curse on the day, parking a shadow over L-Road for the all important morning heating. We had very good soaring numbers for the day but the cloud shaded out a massive area around the tow road.  Randy and Mia were setup ready to go but we had to wait for some sun.. it was almost 1:30 when Randy climbed aboard for the first tow. Typical north north winds (when we get an imbedded high pressure) meant he was going for north tow… always a low tow. At just over 1000agl he pinned off right at the highway and started scratching. I did a few runs up and down the road under him to try and break something off… eventually he started nice climb out to 8000ft asl and was on his way south to Saint Andrews.

Next up was Mia… or at least that was the plan. First up, Radio trouble. We thought we had earlier problem licked but we should have more thoroughly test her radio. Turns out the radio could receive if you using another radio sitting right beside her radio, move 50 feet away and she could not receive….fortunately we had the back-up radio in the truck, quick change and the first problem was solved. Next…….. up on the truck, down the road to stage, go through the pre-launch check and ooooops…. no airspeed probe in her Flytec 6030. If there is one thing you should never do flying a rigid wing in big thermal air is fly without airspeed information. We looked everywhere, tried to come with a alternative solution but in the end, Mia agreed that enough problems had cropped up that it would be bad Mojo to fly so she bagged if for the day.

Turned out Randy was struggling, he managed to get to Wilson Creek but was having to cut the flight short and try to come back. He got shot down for some dirt tasting just SE of Hartline.

Blue, Hot, Strong West, off to the beach….

August 9th, Good weather for a holiday but not for triangle attempts. We spent the morning trying to de-bug a turn in Randy’s VS. Later, it was off to Summer Falls for some swimming and a big mess of BBQ chicken and potato salad. The kind of stuff the normal “folk” do on their day off….. On the way home we checked out some of the local L-Road population:

Idiot Forecasts……

August 7th, XC Skies (GFS, NAM, RAP), NOAA Soaring Forecast, Washington State DOT… heck even my best guess…. every forecast was wrong (or I guess you could say each forecast had just a tiny bit right?).

The big deal was the winds aloft. Everybody was calling for SE through SW….. nobody suggested what we got….NE. Especially NE up to 30km’s !

With Mia running the rig, Randy and I where to test the air. On the ground we knew something was up, there where dust devils and hawks soaring so Randy and I set up a plan to do a triangle up on top (the area around Mansfield).  Randy cut his way in front of me and was first into the air.  Short north tows are always a challenge but after a bit of scratch and a save back at setup he was up and away (drifting with strong NE wind).  I followed shortly after and found the air to be rough and broken. The lift was here, there and everywhere but always broken. You would start to settle into a climb just to have it quit. 

Randy was struggling today (and apparently expanding his vocabulary?). We met up down near Saint Andrews where he thrashing around the sky trying to climb. I was having a little less trouble but probably more a mater of luck then skill, I soon topped out just over 9000ft asl at Saint Andrews. Randy pushed a little further east as I pushed down to Dry Falls (Overlooking “Park Lake”).

GOPR2321

Plenty of high cloud kept interfering with the normal daytime heating so it was a bit of a challenge to break through 6000ft asl. Plenty of times I found great big dust devils that produced nothing of any significance. It seemed you had to work and re-work an area and wait for it to punch you up to the next level. After a couple of hours Randy said he had enough of the ratty air and was going to head back to Mansfield (he promptly found an easy climb up over 8000 but was resigned to heading back). With the 15-20km NE veering more to the East over Hwy2 I kept clawing and kicking the ratty climbs and started to establish a more consistent altitude over 8000ft asl so I continued West to Waterville. On the West side of Jameson Coulee, the peak altitudes started to creep over 9000ft asl and by the time I arrived south of Waterville over Badger Mtn, I had climbed over 10,000. Despite the good heights, it remained a very odd day with plenty of high cloud blocking out the sun and strong E NE winds (now getting over 30kmph above 10,000ft asl).

With Randy landing back in Mansfield I pushed North to Dyer hill.  At the top of McNeil Canyon I was getting a bit desperate as I was down below 6000ft and not liking the prospect. A lone tractor gave some inspiration to go with my perspiration (getting warm at the lower altitudes), the save took me up over my high point of the day (11,800ft asl). From here it was short side trip to Dyer hill (here is a picture of the Dyer hill area that was burnt and the new Antoine fire to the west):

GOPR2327

 

Next, followed by a couple low nasty saves north of Mansfield (real hang on keel bangers) I was onto L- Road to close a 151km FAI triangle.  Landing was in a fresh cut wheat field with ground crew, wind sock and cold drinks waiting.  Not sure why, but I’m guessing the nasty air had me pumped up and I had kind of heat induced snit while breaking down…. as usual my crew ignored me… laughed at me…. hard to find good crew.  Off to Park lake for a wonderful cool off dip (for the dip-sh##) and cruise back, arriving back up on top to another classic Mansfield Nuclear Sunset:

Randys Saint Andrews, Return flight , My 151km FAI triangle.

August 8th, Strong west winds so we bagged the day. Little projects here and there with gear and later a trip to Chelan to go swimming at Blue Lagoon then up to Brewster to visit a great little Mexican restaurant that we like to visit… another hard day (not looking forward to heading back to work next week!).

Interlude… Whoosh! Wheels (a product review)

I have been in search of the best option for  wheels on my A.I.R. Carbon base-tube. Wheels are insurance for those days when things don’t go according to plan.. all alone on an XC flight, thermal at the wrong time and suddenly you find yourself paying for some expensive carbon parts (or worse). With that said, I still don’t fly with wheels. I have yet to find anything that looks right on the sculptured A.I.R. base-tube. Sure you can get wheels… that look like they belong on a Farm tractor! Big rubber tires that may be great for landing but not so great in the drag department.

Below is a set of wheel we got (Via, A.I.R.) for Mia’s VS:

wheel01

Not a bad shape, aerodynamically clean. Very stable on the CB (stays put), can be completely removed to allow the CB to be stored in the D-Cell. Down side?… heavy and sadly jam up, stop turning with any sign of dust (the fine dust of the Columbia basin stops them dead).  Better then nothing but….

Next set we had a look at where the “Radsystem” for the ATOS (Radsystem Link)

 

raederaerodynamischbasis_480

Nice and light, very clean profile, acceptable size. Unfortunately, same old problems with dust (even worse) plus I don’t believe they are good for the base-tube. They need to be mounted inboard of the carbon stock skid points and it leaves a pretty long lever that is likely to damage the base-tube on a hard landing  (that and the fact the contact width of the hub is very narrow, not much area to distribute the load). Oh, and one other nagging issue. The hubs should be left on (because the little tiny screws that hold them in place are most likely to strip or lost. With the hubs left in place you can’t stow your base tube in the D-Cell….. translate : your going to end up with your glider at the flying site and your base tube someplace else? (or at least I would Winking smile )

So, our most recent look at wheels.. the Whoosh! Wheels by Raven Sports 

Below is a photo of the Whoosh! wheels mounted next to a set of Radsystem wheels:

P1000541

The Whoosh Wheels are heavier then the Radsytem but they are stronger and more durable. They also have the ability to easily remove the hub (which btw, is much wider then the Radsystem hub and requires no tools). So far, they appear to have enough clearance to deal with dust but we have yet to establish if we can expect them to survive. The hubs have both a weak and strong points. They are wide and mount outside the stock skid points, leaving only a short lever and IMO better support for the base-tube. The weakness is they do not securely fasten to the base-tube. To keep them in place you are supplied some bicycle “inner tube” …. not a solid solution. Using some heavy duty shrink wrap over top of some 205 leach line (and some industrial double back tape under both the shrink wrap and leach line) I was able to make something a little cleaner (and so far, more secure):

P1000546

Still, I find the hub to be the weak link on the Whoosh! Wheels (ATOS version). The special angle machined into each hub makes it necessary keep them where they belong, and they do have a pretty loose fit to the base-tube profile so that looks to be a difficult task. I think, in the end they need some sort of clamp or hardware to gip the hub to the base-tube in a more positive way (might make this one of my winter projects). For now, Whoosh! Wheels appear to be an ok option even with the issues that I have noted (Mia says she is going to continue to fly with them on her VQ)

BTW, I did leave out one of the other options. “Skids”. These are beautiful works of carbon “art” but for mishaps on rough real world conditions I’m doubtful. They come in two versions, with and without rollers (kind of caterpillar track, that I’m sure would die a rapid death in our desert dust) . (you can find the roller style skids listed at the bottom of the A.I.R. parts page)

(Update 13/08/2012). Thought I would add a few more comments about the Whoosh! Wheels. 

After a few days of our Mansfield dirt, they simply stopped turning (to be honest, this is probably the harshest environment I could ask any product to perform). I’m a little disappointed as they did look as if they had enough clearance to maintain some moment but the “hinged hub” seems to bind or open with the friction of the dust.  I think another issue is the hub can not maintain a good alignment (toe in or out), the twisting of the alignment causes the inner hub to open, acting as a brake. 

One other observation, the version of wheels we are testing have the holes in them (to reduce weight).  Rolling through our mood dust the holes pick up the dirt and sand and dump it onto the edges of the hub, effectively loading the bearing with dirt. If your going to try these wheels in a sandy or dusty environment, order the “solid” wheels (and yes they will weigh more). Last, the pin/dowels used to assemble the wheel half’s are pretty close tolerances making the process of pulling them apart a little challenging.. .I assume they will loosen up with use.

So for now, I do not recommend the Whoosh! Wheels  if your going to be operating in harsh dirt/dusty conditions. Looks like skids will be the better choice…. or the farm tractor tires Winking smile

Have I given up on the Whoosh! Wheels? Nope…. later this fall I might experiment with some form of hub latch to prevent spreading of the inner hub and maintain alignment. If I can’t get satisfactory roll I will continue my quest for a “better wheel”.

Radio Silence… ;-)

(August 5th) In harsh environments its funny how things work…. or not.

Today was going to very hot (over a 100F) and of course “Blue”. The north winds had laid down, the fire on Dyer hill was out or at least in mop up. In addition, winds where shifting from the south so any smoke from the Dyer hill fire would stay north. Randy had joined us and it was Mia’s turn to fly so I agreed to tow.

At 1pm, Mia was first up taking a very soft tow (hardly any lift) finally pinning off well south of the gravel quarry. Lift was broken and she had to work for it. It was soon pretty obvious she had a problem, she stopped receiving (or at least hearing anything). She did a few blind transmission but she soon figured out something was wrong. The “funny” part, we did several radio tests and everything seemed perfect on the ground. Of course Mia has a talent with electronics… they seem to simply die in her hands… now it would be up to her ground electrical support team to solve the “problem” (….. that would be me). 

Despite the radio “glitch” Mia decided to stick to the planned flight down to Dry Falls (same route that Randy was going to take) . After Randy got into the air a tow that was the complete opposite of Mia’s,  with strong lift and a high tow position (and with working radio), we were able to “get a visual” on Mia frequently enough to keep track. Besides, Mia was also flying with her Spot GPS tracker so she was not going to go missing (as long as she did not put one of her electrical curses on it?). When I back tracked into Mansfield with the tow rig and picked up the air conditioned Suzuki I did a quick check of the Spot web page and yes, the Spot was tracking, putting Mia in Saint Andrews and heading south. Well doing the vehicle exchange, we did get a blind transmission from Mia indicating she was in Saint Andrews at 6000ft asl and climbing.

As I left Mansfield to head out on chase, I looked out to the West and sure enough we had another fire starting. At first it looked like a relight of the Dyer Hill fire but turns out it was north of Chelan Airport (and it looked pretty big!)

P1000649

(Antoine 2 Fire, probably weeks worth of poking and prodding for the local fire fighting industry)

Caught up with Randy in Saint Andrews. He was heading south whining about the slow climbs and not getting high…. oh boo-hoo… life is hard.

It took a while but eventually I spotted both Mia and Randy in the air over Highway 2…. looked like Mia was turning around and heading for home. Randy was sticking with the plan and continued to the West to Farmer (so I followed Randy knowing Mia had enough altitude to get at least close to home). Randy made Farmer but landed short of Mansfield on the return leg. Mia made it back to the tow site then back to the house in Mansfield. After picking up Randy we arrived back in Mansfield to help Mia breakdown on the front lawn, then it was off to Park lake to cool everybody off. Hard scratchy day but both pilots where happy. (oh, and Mia’s Radio?… working perfectly when tested on the ground… minor fray in the headset wire so I guess I should replace it)

Mia's 3.4hr 71km OR and Randy's 3.1 hour 67km "almost" OR

(August 6th) A no fly day, thick cloud from the fire was hanging around to the west and some sort of upper disturbance threatening minor thunderstorms so its off to Summer Falls for some R+R.  Was reading Nicole's Blog about the PG nats in Pemberton, Day 1: 4 pilots crashed in trees and 3 parachute deployments…. yikes, wonder how the PR department can spin that bit of news?

Break 101….

Various commitments has pushed us to break from flying over the next few days. On July the 31st, Mia could have flown but she had to be back for 3 days of work so Tuesday was a nice trip down to Park lake for some snorkelling and back to Mansfield where Mia headed back home.

August 1st, I had planned a trip up to Osoyoos to visit my brother from Rock Creek and deliver a solar panel hot water heater. At the end of the day I headed on back to Mansfield (with the mandatory “duty free” Scotch). Approaching the turnoff to Bridgeport I spotted a fire on the West side of Dyer hill  (see previous post for Video showing Dyer Hill) above Brewster. By evening the fire had roared to 8000 acres and had crested the ridge on the plateau :

P1000630

As the sun went down, this photo was taken from over 25km’s away. Still with a strong NW wind…. I went to sleep in Mansfield with a mental plan as to how I would evacuate, fortunately by morning they had held the line and we had no worries.

August, 2nd and 3rd. Further time off to address some work and side commitments…. the 2nd looked epic (through the smoke of the Dyer Hill fire). 

I finally got around to getting some photo’s up on my Picasa site, two albums from this year, Some Photo's of the local Mansfield wildlife (lots of birds) and Mansfield flying and local photos…..

Looks like we will back in the air on Sunday…..

Mansfield Encampment 2012… the “Second Session” (part 1)

For a change Mia and I decided to start the second session of our “Mansfield Encampment” on our own. We snubbed our normal house guests and opted for a few private days crewing for each other.

July 28th.  Mia volunteered to go first as “tow-chief”. The weather was hot and blue, light winds and a weak soaring forecast. As we headed out to the tow site there were the usual number of dust devils stalking the local fields so it looked like there would be some reasonable lift.  With a bit of a late start (for me), I was up and away after 1pm. A single tow made for a light day at the tow site so Mia was quickly back into Mansfield with the tow rig, switched vehicles for chase (into the XL7) and was only a few km’s behind has I worked my way SE to Dry falls for my first turn point.  Lift was weak and broken, at least there was not too much sink on glides.  After I made Dry Falls, I got into a bit of trouble over highway 2. Heading west, back near L-Road I had unsuccessfully chased 2 or 3 dust devils with no luck and was hanging onto my last chance when I was finally able to re-establish some height to seek out some better climbs. As usual, a little bit of suffering down here pays off with some nice climbs….. only to wander into the same trap again?

I had intended to go to Waterville but the slow climbs where starting to take their toll remaining soaring time for the day so I turned early (a few km’s east of Douglas) and headed north. Of course, having given up on the planned task, things improved. Heading north I watch a sailplane lower but climbing fast just west of Withrow. By the time I got there he had topped out and was heading east but I was thank full he had marked such a great thermal. I soon climbed to 9500ft asl in a nice smooth 1000 up and was inspired to try and salvage some of todays task. By now Mia had joined up with the chase vehicle and was directly below as I headed for my Dyer hill turn point. Staying high was easy with the air on the rim being very buoyant.  I peaked over 10,000ft on several occasions so it was an easy trip up to Dyer hill then back to the tow site at L+13.

When I landed in 1 foot deep moon dust at our highway LZ, Mia was waiting with some cool refreshments (bottled water….. really Winking smile )  followed by a quick takedown, trip to the lake to reward my excellent ground crew and back home for steaks and Scotch.

My 138 km FAI triangle flight.

 

July 29th. Still blue and hot, today with some high thin cloud and some minor haze. Mia’s turn to tackle what looked like lighter air then the day before.  Mia is flying her new ATOS VQ with its amazing sink rate…. something she was going to need today. Starting with her tow, Mia found the lift weak and broken.  In the beginning, reaching 8000ft asl was high. To top it off, she had to contend with a 10-15 mph SW wind…. in light air made for a very hard day.  It was a very hard slog to get all the way down to the gravel pits west of Farmer  (with only one climb taking her near 10,000ft asl) when  she decided that it was time to head back to the tow site (about the only time of day that I was not able to keep up with her as the tail wind made it easy for her to pass me in the chase vehicle heading back to Mansfield).

SE of Mansfield Mia staged her final battle to get back to the tow site.  3 times she dug out from less then 4000ft asl (ground is 2300) only to hit a late day wall between 5000 and 6000 ft.  After loosing the third battle to get the altitude need to get back to the tow site, Mia decided that the freshly cut wheat field that I had found her and the thought of a cool dip in Park lake was enough to call it quits and land. On the ground, despite the lack of lift there was plenty of activity (winds gusting 5-20kms). As I called out wind conditions on the radio Mia set up her approach. She had lined up a perfect final when the bottom dropped out (a thermal passing through?), amazingly, she pulled off a perfect nose up, no step landing in what turned out to be next to no wind!

Again, as a team we had the glider in the bag and off to the lake in less then 30 minutes… tough day but I was proud of Mia’s effort on what was a very challenging day. Mia's hard fought 76km FAI triangle.

July 30th. Strange brew today. Early, 3-4 am in the morning some strange weather moved through.  We woke up to blue skies with a band of upper Q’s. Often a sign that some instability had found its way into the stable air mass (and often the kind of weather that would lead to thunderstorms).

Mia crewed and and I flew. This time there was lots of activity at the tow site. So much, that I considered not flying (especially given that winds aloft where forecast to be over 15 mph). It calmed down enough at the tow site I decided to give it a try. The tow was STRONG, several times while under tow I was showing 1400ftpm up… thing is, normally you would pin off in that kind of air but every time I hit the strong lift I was in a poor position to release. One thing you don’t want to do to your tow operator, is release your towline with a bad recovery chute over rough terrain! Dragging 4000ft of towline out 4ft high sage in 90degree “F’n” heat, is not going to make you popular…. not recommended if the tow operator is the one cooking your next meal…. or worse….

Finally the combination of a clean drop zone, strong lift inspired me to release, “pop”….. out comes a good clean chute and the towline was on its way back to the truck and I was heading for the sky at 500ftpm. At first the air seemed smooth but for sure there was a strong south wind that I was going to need to deal with. Fortunately a plan presented itself. Good Q’s where forming up over the tow site and a good solid street was forming to the West running from Pearl hill (near Chief Joseph Dam) all the way down to Waterville. I left the tow site heading straight north to Pearl hill (25-30kms) and joined up under this beautiful cloud street. Mind you, it was a beautiful cloud street with an attitude! The air was rough, strong lift that was broken and unpredictable. Base was near 11,000 and I regularly pulled out of lift at 10,000 choosing to press on to Waterville staying well clear of the clouds.

My intended turn point was Waterville. Unfortunately, the street fizzled out well short and diving into the blue is often risky on a day where clouds are present….. today proved no different. Before long I was below 5000ft asl and hanging onto to every bug fart I could find . The only positive thing was the fact near Waterville the winds had shifted west and I was able to push my southerly distance enough that I was able to allow myself to drift toward my next turn point (Dry Falls). As I mentioned earlier, this place seems to reward your efforts…. my struggle soon allowed me some freedom to do a little more searching and soon It was back up over 9000ft asl for an easy crossing of Jameson Coulee (under the still intact cloud street). From here it was back into the blue (yikes)…. and just like before the lift took a holiday. By now I had enough of the rough air and turned short of Dry Falls and headed back north to the tow site just east of Saint Andrews.  Here, the winds were back to a southerly heading and with a few short climbs I was able to drift my way home to the tow site in rough trashy air. Mia was waiting with a wind sock, weather information on the radio, cooler full of beverages and a chuffer driven ride to Park lake to sooth some nerves frazzled by the days challenging air. Life is good (and my ground crew even better!) My 140km FAI triangle.

Mansfield Encampment, Session 1 (part 3)….

Best to get this “Session 1” out of the way since session "2” is now underway ….

July 8th, Blue with good potential for altitude. Mike had an interesting day, he had to re-launch (rare this season) but somewhere during his first landing he damaged his sail on the left wing. (later on some video we could see that it lightly touched the ground).

The damage went un-noticed until he was up on his second flight. He could see a small section of 3” x  2” cloth hanging down out near the leading edge. After a bit of discussion over the radio it was decided to head back into to Mansfield and land. After inspection we figured there must have been a rock in the field that cut the cloth. Later that evening I helped him pull the sail and by next morning with the help of Jeff the sail was repaired and ready to go.

Mike's drama queen flight..

Other flights from the 8th…

Jorge's drunken meandering 45km triangle ....

Randy's 75km local triangle

My 140km triangle had some interesting moments, out near the western rim (Waterville) I was suddenly able to crack through the lower air and climb up to 12,000+ ft asl so I started a leg across Farnham and McNeil canyon up to Dyer hill. Crossed over a familiar PG pilot that turned out to be Alex Raymond… doing his version of a Chelan “Sammy”, very low on the rim, heading south from Wells dam. I was surprised to find out he made it back. At least he had the option to walk home (and it would have been a very long walk).  From Dyer it was back to the tow site and home to Mansfield for cool Becks (and to help Mike pull his sail on his VR).

Nic Voss, a pilot from the “good old days” arrived and in exchange for room, meals and Scotch joined us to run the rig for a few days. Sadly, Jorge and Michele  ended their stay… and as usual where late leaving to be where ever they had to go Winking smile

July 9th, weather, wind with potential overdevelopment in the forecast so it was a trip to summer falls for a day off (Mike was getting his sail repaired) and Randy had to head back to work.

July 10th

Mia's 115km OR

Mikes 150 km FAI triangle...

Today I managed to put together my own personal best for FAI triangles (making it home). It was inspirational as I did not feel it was a very good day. The early first leg was very slow and hard work. Not the kind of day I was expecting to go well. Once turned at my southern turn point I pushed north to join up with Mike (who had turned near Wilson Creek). Things improved dramatically on this second leg , for a change I had clouds to chase and someone out ahead that was indicating good lift.

GOPR2102

My objective was a turn point near the Columbia river north of Wilbur but a big blue hole forced me to cut short the leg (still 70+ km’s) and head for home. Just north of Highland I stumbled across Mike where we set up a crossing for Banks lake, timing some nicely spaced cloud for a good arrival on the west side of the lake. Here Mike and split up, he pushed home, I hung out in some nice smooth air, peaking over 12,000 near the tow road so I went on a big long glide out toward Wells dam and the Columbia river to the west. About 20km’s past Mansfield I turn and ran for home to end the day.

My 235km FAI triangle (personal best)

P1000500

July, 11th. Day off for me. Mia and Mike did and excellent job running out into the blue. Nick and I ran chase in what we called the cemetery tour, waiting at all the cool shady rest stops of Wilbur, Almira, Hartline and Mold cemetery's. 

Mia's 130km flat triangle

Mikes 178km FAI triangle (his personal best!) Nice Job Mike!

July 12th. Odd high cloud, good soaring numbers but a strange looking day. Not to inspired but I took a tow. Found the air to be pretty nasty so suggested to Mia to bag the day (she did). I poked around, heading west in strong ratty air to meet up with a PG gaggle over Farnham canyon (full of Ice Peak comp wings). I stayed above the mess peaking out well over 12,000 ft but did not like feel of the day so I pushed south to Farmer. There everything went soft and I only managed to cross back over to the east side of Jamason coulee and pull a few k’s north. There Mia and Mike caught up and helped me pick out an LZ. Wind sock and a breeze and I still duffed my landing! Dirt tasting (nobodies perfect):

My 80km flight… Session “2” coming soon… Cheers

Mansfield Encampment, “The first session” (part 2)….

July 6th, Getting hotter and lots of blue sky. Occasionally Q’s would pop in the distance to give inspiration to the perspiration. I teamed up with Michael to run the rig with Mia, Jorge, Mike and last nights late arrival Randy pilots for the day.

P1000462

Mia gets ready to fly her new ATOS VQ12

The day required a bit more work but winds were light. Noon and Mia was up for her first tow on her new VQ, pinned off and started scratching up from the tow site. Mike was next, followed by Randy and Jorge took the last tow. Everybody up and away with no re-launches (now that’s the way you should treat your ground crew!).  It was a mish-mash of plans, Mia, Mike and Jorge all wandered off in the direction of Waterville, Randy on the other hand pressed straight south down the tow road. With everybody spread out we decided to head out in two chase vehicles. After some early struggles, most of the crew started getting pretty high (10-11,000ft asl) with the exception of Jorge who unfortunately got caught out near Withrow and landed. Randy put together a nice little 100km FAI triangle, Mia a 90km OR (her first VQ XC) and as usual the “Air Pig” Mike with a 127km FAI triangle, all landing back at L-Road in light SE breeze. We pushed a quick trip down to Park Lake for a swim and some beverages then back to Mansfield for dinner… and yes an evening night cap.

July 7th, More blue… more heat and light East winds but today also had some sort of upper system with very high cumulous clouds (based at 15-16,000?). This was to be a hard work day. For Mike, he was going to serve his first full day on the rig (and not in the air!) With Michael has his instructor/observer Mike got to find out just what it would be like to run the other end of the towline…. which btw is a requirement if your towing with us.

There was some haze in the air and the upper air instability so it was anybody’s guess as to what was to be expected (all of the soaring forecasts could not agree).  My call was to attempt to head SE, quartering into the light East winds. With a bit of a slow start, I soon found myself busting 10,000ft asl near Saint Andrews (the patron saint of sink?) and pushed south to Wilson creek. The upper clouds proved interesting but I was not sure there was any connection to the lift below.  Randy had a wonderful climb out from tow and decided to push straight east to Sims corner where he spent a bunch of time moaning about being low…(and based on his trace, he got freaking low!) but after some persistent grovelling punched a nice climb back up over 10,000… then got low… then climbed out and finally was east bound across Banks Lake (where his faint radio transmission continued with complaints about struggling… come to think of it Randy only seems to use his radio when he’s getting low and having to think about landing… which is usually followed by an epic climb Winking smile ).  Mia, on the other hand dispensed with the dramatics and after two climbs also crossed Banks. Jorge followed up the rear with close to an hour of low level grinding and was eventually rewarded with a couple good climbs to cross Banks to the east.

By this time, I found myself cautiously trying to pick my way into my southern declared turn point called the “MicrowaveNE” south east of Wilson Creek. Early high altitudes were gone, the upper Q’s where producing nothing and the east wind was getting stronger.  I tagged the turn point and started pushing north to Irby.  There I got real, real…. real low. I called Mike on the radio and suggested that if he did not hear from me in the next while I would be down on the Irby plateau (north of the town of Irby). I got a confirmation that was none to confident… obviously had no idea where Irby was! Next I hear Randy is landing in Wilbur, Mia was turning around north of Hartline and Jorge was flailing around North of Almira. Michael in the second chase vehicle was heading back to Mansfield for Mia, for sure if I sunk out I was going to sitting in the dirt and heat for quite some time (as Mike searched out Irby on his smart phone). I dug deep, gave up on heading north and just let the bug farts that where keeping me up send me back toward Wilson Creek and hopefully into an area much easier for pickup.  With some hard work I was able to drift and search and keep my ass off the ground. Up north Jorge was doing much the same, in fact he was sure he was going to land but managed to make another save. Meanwhile, back in Mansfield Mia managed a nice no-wind, tail wind landing and was walking her glider back to the front lawn.

Just East of the Wilson Creek coulee, at 6500 ft asl, I watched a Cessna Citation jet fly south below me at what I estimated to be 5000ft asl (I suspect heading direct to Ephrata?). At least now I was starting to gain some altitude and I went to work on heading NW to Mansfield.  Randy was picked up by Mike, Jorge was now working his way to Hartline, looked like we might actually find our way back to Mansfield to join Mia. North of Wilson Creek I took a nice slow climb up over 11,000 ft asl and made for a crossing south of Coulee City back up to Saint Andrews and on my way back home. Arriving in Mansfield winds where light out of the north, making for a tricky (but perfect) landing…. even I was surprised Winking smile 

Unfortunately, it was getting late and Jorge ran out of time to get home. He did manage to cross over Dry Falls but was unable to re-establish any height on the west side. Apparently in a rather unique landing spot that later required me vacuuming my radiator to clear off a good thick coat of wheat chaff and scrub brush that some how made it through the grill… still Jorge’s flight was a real hard days work and brought him back to the house with a big smile! Of course Mike also came back with an appreciation of the hard work that goes into crewing for a bunch of knuckleheads!

Mansfield Encampment, “The first session” (part 1)….

For a variety of reason, this years encampment is being broken down into two session. The first session ran from June 29th to July 16th. This posting is not intended to be a daily flight log but more of a summary of some of the highlights from this first half of the encampment.

In a casual way, the summer objectives usually revolves around flying FAI triangles. The bigger the better. Often if conditions look exceptional or the weather forecast fools us into believing that something exceptional could happen…. we like to declare a record attempt. Mia is looking for her first 200km FAI triangle, I’m hoping for my first 300km.  If all else fails, the secondary objective is to log as many km’s as possible (racking up points for our OLC fun…) and if at all possible, as many of those km’s ending on the front lawn in Mansfield with a cold Beck’s from the fridge!

First day (Friday June 29th) in Mansfield was spent getting the place in shape, cutting the never ending forest of lawn, stocking the fridge and getting the rig in order. Not really prime towing conditions anyway with lots of wind and plenty of weather action (overdevelopment in the area).  Later that evening, Mia caught me sleeping in the living room listening to NPR… well sort of… I had dozed off with a glass of Scotch in my hand… Bliss….

Saturday June 30th, weather. Randy Pankew (proud owner of Mia’s “Old” ATOS VS) showed up but decided that the weather was a little on the industrial side so it was off to Park Lake for swim, and back to the shack for dinner.  Big thunderstorm pounded the banks lake region late in the day as we watched the spectacular display from Mansfield. (posted earlier on July 13th). The next day there was an amazing amount of moister still hanging in the air but Randy had to head home the next day so I got him inspired to join me for some flying (posted about the flights in an earlier post). After that, with poor weather in the forecast (not unusual for late June, early July) Mia decided to head back for a few extra days of work and Randy headed home, leaving me to take on various tasks around the shack including hard wiring our web cams that we hope to put up for public viewing. 

On July 4th, early AM,  Mike Bomstad from Spokane pulled into town with his tongue dragging on the ground desperate for some airtime so I agreed I would yank the big baby up. Of course it only because he is always good for video footage : (Mikes 07/04 flight ).  (Mike's landing from a different angle ).  After a little power gloating,  Mike and I where joined my Jorge and Michael (also from Spokane with Jorge being our token “Flex” pilot Winking smile ) Later that night Mia returned to find us all over indulging in Scotch… after a few tsk tsk tsk’s… she joined us.

July 5th was the kind of day that makes us smile. Mia teamed up with Michael (Jorge’s guardian and baby sitter) to get all three of the children into the air. Lots of blue sky with just the occasional Q popping south of the tow site. Both Mike and I plunged off to the south. Jorge headed off to the west toward Waterville. Down south toward the Beezly hills Mike and I where struggling to stay up (or at least making any headway toward our planned turn point and seldom getting over 7500asl ) so both of us bailed on our task and headed West over Rim Rock (a bizarre little red neck camp ground on the east side of Jameson coulee and off to the flats south of Farmer. From this point, things started getting good. Back up over 12,000 where a rigid wing really belongs Winking smile  Mike agreed to a little recon flight into the mountains on the west side of the Columbia river… this was going to be a first for both of us. Despite the 15-18 mph headwind the crossing was pretty encouraging, with beautiful clouds up ahead we pressed on.

Unfortunately, the great looking clouds where not producing any of the great lift we had left behind. NE of Cashmere and getting down below 9000asl and nothing that looked like a suitable emergency LZ… and we were both turning into cowards, I announced I had enough of these stinking mountains and declared it was time to head home. (no protest from Mike!)…. so with a good tail wind we plunged on back to our familiar flats just west of Waterville. Arriving back below 5000 asl we were promptly given a good slapping around for being unfaithful! By the time I had made my apologies for having been unfaithful I was digging myself out of Pine Canyon from 3900ft (600agl). With a little “I’m sorry” the broken ratty lift surged into 1200-1400 straight up over 10,000 and a wonderful set of clouds had formed a well marked street back to Mansfield (Clouds that Jorge had spent his whole flight enjoying…. pays to be faithful). Mike also got spanked, and with a similar prayer was also blessed with a nice climb and ended up a little behind but chasing me home.

Jorge announced that  he had gone from Waterville, out north of Sim’s to Leahy and was making for the beer fridge in Mansfield.  Clouds were still great so Mike and I headed off toward Leahy as there was plenty of sky to be enjoyed.  Mike was starting to snivel about getting cold hands (we were now easily getting up to 11,000+ ft asl)  so he called his turn just prior to Leahy and headed home. I took a more northern line and decided to explore Pearl Hill (NW of Leahy) and after bumping around the cloud base at 12,500+ I decided to pull the pin with nearly a 30km final glide home to the front lawn in Mansfield. I think we all duffed our landings (in a minor way)… I was late with my flair and skidded on… no tubes bent,. Our “near the house” LZ is a little rough and the wild grass makes for a tricky landing spot. I had tried to buzz cut a clear spot but I have to admit… allot of work yielded only a small clearing, that I promptly missed in the light switching conditions. Oh well, no bruises and the beer was cold! Our flights:

(Jorge's 120km Flexi flight) (Mikes "little" 184km triangle flight) (My "massive" 197km FAI triangle ;-) )

More to come…… Cheers

Mike’s Lightning Video….

Mike sent me an edited Iphone video of lightning storm under the power-lines looking east toward Mansfield. Sound track… well not my choice Winking smile (perhaps the Door’s “Riders on the Storm”?)… Nice job Mike!

3 hours later…..

Like I said, this place can be very big. This photo was taken three hours later (after the photo in the previous post) looking back at Mansfield from 25km’s away. At the end of the day this thing laid down numerous lightning strikes and caused at least two fires.

Strange things said and done…..

The Columbia basin produces big air. You need to respect the place or it can kick your ass big time. Why just the other day while flying near Withrow and monitoring 146.415 (our local op frequency) we had some familiar “no call sign” Russian PG’ers (and others) talking their way onto the flats from the Butte when there was a brief strange transmission ……. “Throw your Chute ! “ ….. (brief silence)…. “Nice save!”.

Not sure what the whole storey was but undeniably somebody just got schooled.

Over the last few days, there has been a local Chelan Butte PG comp underway, they have done well with reasonably good comp conditions with some very respectable performances. In the last two days, tasks where pushed with very high chances of thunderstorms. I’m not chastising anybody ( I’m sure they are all big boys and girls) but the second of these two days did “blow up” and had some serious potential . The task was called and it rained PG’s in Mansfield, later even a tandem sailplane from Twisp was forced to seek shelter at the Mansfield airport. I guess all I’m saying is you can “poke the bear” but remember…. the “bear does bite”.

Mia and I tend to seldom want to challenge the place when the forecast includes overdevelopment. Something about dragging 4000ft of towlines through statically charge atmosphere with a “kite” on the end of the line?

If I were to offer some advice to PG pilots who want to fly the Columbia Basin (Chelan and surrounding area), Unless stable, you should have at least 500+hours of experience. You should try to team up with pilots who know the area. Expect to encounter air far beyond anything you have ever experienced (even in an SIV). This is not a place to fly for the timid. Pilots who do not have a masterful grasp of controlling and recovering their wings should not be out here. I fully admit, as a PG pilot this place is way beyond my skills and comfort zone. I have close to 150 hours on the PG and would never dream of flying this place on anything but the quietest of days, preferably well into the calmer days of August and September.

Todays morning weather (11am) with severe thunderstorms in the forecast….
