This is a voluntary pop quiz.



You're circling in a 30 degree left bank at 3000 AGL.



You hear a thunk and the glider enters a spin. Your practiced spin

recovery technique does not work in the usual amount of time. You look

in

the direction of the thunk and see that the left spoiler is full open,

you

confirm that the spoiler control handle is in the fully closed position.

A

quick look confirms that the right spoiler is full closed.



What do you do next? Why did the left spoiler pop open. What just

happened?



To derive the full benefit of this exercise, you might respond to this

thread with your answer before looking at any of the other replies.



My hypothetical solution and explanation follows as the next comment.



Deploy the other spoiler/airbrake. It is unlikely that the ailerons/rudder

will have the authority to counteract the rolling/yawing moment produced by

a single deployment. Normal spin recovery to approach attitude/speed. With

both spoilers deployed you are still flying a glider, I concede that it is

a glider with a crap gliding angle but if you have ever flown a primary you

will be right at home. You can fly a normal circuit (pattern) with the

normal rules for a glide angle that you now have. It may be wise to ensure

that you do not go any further downwind than the boundary of your selected

landing area, depending on length available, but again the normal rules

apply.

Heck I've flown Hang Gliders for 38 years so you simply fly it as a trainer -
