In gliding, especially with state of the art gliders (L/D in the 40 to
60 range), failure of your landing drag devices (dive brakes, 90 degree
flaps, even tail chutes) can be a real emergency - you can float in
ground effect for miles without slowing down, unable to land! And with
wingspans of 50 to 80+ feet, slipping at ground effect altitude is a
dangerous proposition! In the pattern, I would much rather have my
gear fail to extend than my spoilers fail!
