Aside from the instability of a DHV-2/3 glider, beginners can become overwhelmed by the amount of feedback that a high-performance glider delivers. Information returned to the pilot through the brake lines and harness can be a lifesaver for someone with experience, but for others it can scare them right out of the air. I provide below a few examples of the kind of conversation a canopy can have with its pilot during a typical thermal flight.
Canopy up and over, launch complete. Proceeding one-niner kilometers per hour, heading two-seven-zero degrees... left brake-OK, left-OK, ok ok ok ok. Right turn initiation complete, trimming, bank angle nominal. Ok ok. lift encountered, reading four-zero-zero feet per minute. Ok ok ok. Core is to the left, turn initiation to left complete, bank angle flat. Ok ok. lift niner-zero-zero feet per minute. left bump--OK, left-bump---OK. Ok ok, exiting thermal, right side decompression, correction complete. Right side decomp-- RIGHTMOST THIRTEEN CELLS READ NEGATIVE FUNCTION, correction, correction, correction complete, course change minus-five degrees. Ok ok ok. Altitude sufficient for crossing to next peak with eight-point-zero glide average. Transition initiated, two-point-zero kilometers to next turn point.
Landing spot approaching, trim speed, boots two feet AGL. Brakes applied for speed-to-altitude transition, maintaining altitude at two feet AGL, airspeed now near stall, touchdown complete at three kilometers per hour. Well done captain.
I think you've had enough exercise for one day chum, time to land. Careful, we're comin' in hot, comin', watch the.. TOO MUCH BRAKE BUTTHEAD, we're goin' up again! Ain't nobody told you about energy retention? Fine, now we're gonna overshoot. Don't put me in the bush, don't put me in.. Oh, that's just GREAT, you MORON, I'm in the bushes!
Time to land? Thank you madam, a prudent choice. If you would prefer I can call ahead and have cocktails waiting?... Very well madam. Slowly, slowly done! A perfect landing, madam. Have you lost weight?
