15. The air mass is called unstable if there are:

stratified clouds in it. convective vertical motions in it. inversions in it.

16. When entering a thermal current:

the glider informs the pilot by its movements about the strength of the lift and usually also about which direction is better to turn. the canopy always tends to collapse and therefore the pilot must brake. the glider usually tends to collapse and therefore the pilot should break a bit before turning.

17. So called escaping maneuvers include:

spiral, spin and B-stall. spiral, full-stall and B-stall. spiral, big ears and B-stall.

18. When entering a thermal current:

the canopy shoots forward and can collapse. the canopy tilts sidewards and can get asymmetric collapse. the canopy lilts backwards and can shoot forward afterwards.

the canopy shoots forward and there is a danger of frontal collapse. the canopy tilts sidewards and can get asymmetric collapse. the canopy tilts backwards and can shoot forward afterwards.

20. In stronger wind it is better to take off:

down at a sufficient distance from the mountain top. so that the canopy is at the level of mountain top and the pilot a bit lower. at the top of the mountain.

21. What are the possible wind direction indicators in a strange place where there is no wind sock?

27. Contour lines are curves connecting points of the same:

declination. negative hight, so called dephtines. alitude.

28. A glider with an asymmetric collapse tends to:

fall quickly and therefore it is necessary to prevent such situations at any cost. fly on, but pilots tend to do unwise piloting inputs. turn rapidly to the side with the collapse and then rotate or slowly return into straight flight.

29. For emergency landing a pilot would rather choose:

a lonely tree. dense forest. a forest road.

30. During ground handling training the glider lifts the pilot above the ground in a wind gust unexpectedly. The correct procedure is:

to pull the steering fully. to release the steering and fly, steer and land back to the ground. to pull and release the steering repeatedly and by such flapping go back to the ground.

31. After an asymmetric collapse the correct procedure is:

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 pulling the steering on the not collapsed side quickly and fully to help the regeneration of the canopy. no sudden piloting inputs; a certified paraglider will return into straight flight itself.

32. Before a landing into still water it is necessary:

to turn the glider against the wind. to jump out of the harness about 3 to 5 m above the water surface. to undo the harness buckles so it was possible to leave it at the moment of contact with water.

33. In strong wind a pilot flew in a place where his ground speed against the wind is zero:

He should keep flying against the wind and emergency-land in the terrain below him. He should fly with sidewind or windwards as the terrain allows as far as possible to an alternative landing field. He should step in the speed bar and make big ears.

45. During ridge soaring after a collapse about 10 meters above ground a pilot landed hard on his left side; He is obviously shaken, however gets up, then collapses, is pale, reports pain in his hip, shakes, he wants to sleep, a little confused, but strictly refuses an offered call for an ambulance. The procedure will be:

We are trying to calm him down, keep him in a position which is the most comfortable for him, cover him and call the emergency services. We lay him in shade into semi sitting position and check him occasionally during flying. If his condition gets worse, we call help. We lay him in the anti-shock position with his feet up, cover him and call an ambulance.
