250KM FAI Triangle

 

 

Whitewater 250KM FAI Triangle

The extraordinarily epic weather continued this week in the upper Midwest with multiple soaring days. On Wednesday high cloudbase (9000’) and light winds warranted a long triangle task.  I awoke early to confirm the weather was holding and selected two 250km tasks one of which I extended to 300km in the event the climbrates were exceptionally strong. On my way to Whitewater, WI our longstanding aerotow park that friend Danny Lange operates, I fired off a text to Kris Grzyb about the weather. He responded that he was leaving work to come up and fly. The top of the lift was predicted to be over 5000’ at 10:00 so the plan was to be ready to takeoff when the cumulus clouds started popping. Kris arrived and we selected a 250km FAI triangle around the city of Madison in a clockwise direction to ensure any high clouds that may arrive from the west later in the day wouldn’t shut the conditions down.

Airspace would be an issue should we have any drift however there was plenty of room on this task to divert should we need to. Danny pulled me and my Wills Wing T3 Team 144 up at 11:11 through a lot of sink before finding lift under a nice cloud to the north. The climb was strong at 430fpm to 7500’; unbelievable for so early in the day. Clouds were lined up to the west toward Lake Koshkonong however the lift near the lake was broken. Better clouds to the northwest resulted in good climbs, one with Kris to over 8200’ right at the edge of a nice street. The day was shaping up well however the street didn’t work very well for me as I flew under multiple clouds missing the lift and plummeted to 800’ above the ground.  A lucky climb over a tractor plowing his field took me to 8000’ at an average climbrate of 424fpm! Whew back in the game again however Kris was long gone. I continued to plow west under four clouds without a decent climb before managing to get back above 7000’ again at the first turnpoint. It took a long time to get there and I began to doubt whether the task could be finished however the clouds to the northeast looked powerful with dark flat bottoms indicating strong lift. The next climb was to cloudbase at 8700’ and I hit 8 in a row topping out near base in each thermal with the best average climb at 702fpm and top altitude over 9200’! And with that I was at the second turnpoint of Gilbert in just over 2 hours. On this leg I was beginning to feel fatigued so gorped down a Clif Shot Espresso energy gel, chased it with some water and within minutes the tenseness in my lower back was gone. Radio problems kept Kris and I separated most of the flight. I could hear him sporadically (and he, me) however the communications were garbled with a lot of static; not really discernible. It was tough to leave the line of clouds that led to Gilbert however the last leg of the flight was 78km back to Whitewater to the southeast. Unfortunately there was big blue hole on the course line with the only reachable clouds to the south.  It turns out both of us took this path. Flying toward the Madison Airport was a bit daunting as we were staring right down the barrel of the main runway. Thankfully no air traffic was on our flight path. I climbed from 3600’ to 6200’, took a look at the airspace on the 6030 map page and knew the only legal path was to head east. This was a good decision as I topped out at 8500’ and headed southeast where Kris was thermaling under the next cloud. Our contact was only temporary as he left up high and I took another path. We never saw each other again. The climbs were now suppressed as the day was getting long; 250fpm was the new norm and the lift was super smooth. The cumulus clouds were dissipating rapidly so the visual clues of lift were farther apart and less prominent. South of US Rte 94 I found a thermal in the blue and settled in for a long climb. I relaxed and concentrated on maximizing my climb eventually leaving at 7400’, 20 miles from goal needing a 16:1 glide ratio to make it in. Heading southeast on a long glide into the blue I was maintaining my numbers but wasn’t confident they would last. Off to the east near Jefferson there were the remnants of the last clouds in the sky so changed direction to get one last climb. Ever so faint wisps of cloud were forming before the clouds in front of me where I eventually found lift, starting at 100fpm and slowly ramping up over the next 15 minutes to 450fpm. I left at 7000’ now needing a 10:1 glide with the 6030 showing that I would arrive at 2000’. Woohoo, I was going to make it. The final glide was surreal as I flew over familiar territory noting the landmarks beneath with the airport slowly rising in the distance. The roller coaster of emotions from the day were now peaking after the low 800’ save early in the flight to the 1000+fpm peak climb on the second leg to this, the thrill of flying my longest triangle.  I was totally stoked.  There isn’t anything much better than to set an aggressive goal that is on the edge of being achievable and then going out and making it happen.  I touched down at the airport after flying for 7hrs and 56 minutes and over 250km (150 miles). Kris arrived ahead of me and was already celebrating with a fine Polish beer. What an incredible day!
