Hi
While all advise should be never fly in rain especially snow. How much rain can you get away with?
A few years back i was doing the SSDR rally flying my old V5 and trusty Ozone speedster, both myself and my flying buddy had a shower passing in front of us. We both held our course as it looked as tho it would pass in front of us, unfortunately holding our course was to prove the wrong choice and we got wet, trying to go around and getting wetter and wetter, By the time we passed the cloud and back into the sunshine we were both soaking wet, Not wanting to slow our progress call it hard core, brave or god dam stupid we carried on flying... Full trims out never touching the brakes for fear of a full parachute stall.. Looking back we were both very lucky!!!
Fast forward to the present, Flying a new wing i encountered a very minor patch of drizzle, No more than a few spots on the goggles, This time i was flying FULL SLOW as i had a low airtime pilot with me, who was flying on fast trims to keep up.. We passed the small patch of rain in about 1-2mins everything was dry my wing started to twitch pitch then violently roll... Stalling back then surging forward to the horizon ... My GPS showed 48kph forward speed down to 10kph as my wing was stalling out on me,
One second i thought i had the glider under control then the next the circle of stall, pitching and yawing started all over again.. from 1000ft down to around 300-400ft i had thoughts of calling it a day and chucking my reserve but as soon as i went for the handle the glider seemed to be ok... again stall pitch.. down to about 200ft i thought about pushing out the trims to accelerate the glider, BUT i didn't do this as i doubted my own judgement... I 'landed' at 8M Per second... According to the wings designer this was my only option to regain control of the wing again....
Only Suffering from whiplash and bruising...I am lucky to be walking!!!
All High end wings should not be flown when raining!! if you get caught out fly full fast trims NEVER touch the brakes just tips until your feet touch down...
All the new crop of wings with there smoother surfaces will suffer from getting wet more so than the older wrinkly old gliders..
DO NOT fly in rain!!
Fly safe
