You have to adjust every circuit in a glider. It would be good for power pilots to do some gliding
Agree in spades.
As I recall the USAF used to (perhaps still does?) send its sprog pilots up in gliders to teach things like secondary control effects.
Confess to being somewhat worried about basic flying skills when I read some of this stuff. What the hell are people doing with head down, looking at instruments perhaps even fiddling with GPS when they are trying to land?
