1. When the surface load changes the glide ratio:

changes because the relation between lift and drag does not change. does not change because the relation between lift coefficient and drag coefficient does not change. changes because effective bearing area is the same.

28. If one side of canopy is stalled, the pilot should:

release the steering continuously. hold down the already pulled steering and counter-steer the rotation by weight-shift. pull the second steering fully and then release both.

29. After an asymmetric collapse the correct procedure is:

no sudden piloting inputs; a certified paraglider will return into straight flight itself. pulling the steering on the not collapsed side quickly and fully to help the regeneration of the canopy. weight shift in the not collapsed side of the glider and brake the same side slightly to stop rotation.maximálně se vyklonit na nezaklopenou stranu a také ji přibrzdit tak, aby nedošlo k rotaci
