Interesting article on stalls and avoiding stalling in the latest
"Australian Flying". Basically don't pull the stick back too far!
I guess we think we know that but the article makes it quite clear
what happens. Seems stick position awareness might be the key to in
training to avoid unintended stalling.
A couple of thoughts:
Maybe there should be a display of stick position in the pilot's
field of view?
Maybe a strong compression spring could be arranged so that at the
stick position for minimum sink pulling the stick further back
requires noticeable extra effort. The position will depend on the C
of G position but this could be dialled in after doing that calculation.
Yes, the glider can be stalled by a vertical gust but as the glider
responds to the gust the angle of attack rapidly decreases. This
takes only a fraction of a second.
Angle of attack based stall warning systems in gliders haven't been
all that successful because of the warnings which occur in gusts
while thermalling.
