in the temperate zones. over the poles. over the equatorial regions.

15. With increasing height, atmospheric pressure:

increases and in the hight of 5.5 km is double of its value at the see level. decreases and in the hight of 5.5 km is a half of its value at the see level. does not change.

16. I increase the flight speed by:

pulling the trimmers. depressing the speed system. pulling a bit of steering.

17. When entering a downdraft:

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

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

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

19. Spiral is performed by:

weight shift in the intended turning side, pulling the steering on that side and pulling down the front riser on the other side. pulling at first both the brakes and then loosening one brake all the way up while the other pulling completely down - the paraglider descends circling in a dynamic and fast rotation. a smooth transition from a turn into sharper and sharper turn via gradually increased brake input and body weight shift in the same side in which turning.

20. B-stall is performed by:

by pulling the second row risers. by gradual pulling the rear row risers. by gradual pulling the first row risers.

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

27. 9 cm in map with 1 : 500 000 scale refers of real distance:

50 km 45 km 60 km

28. In mid-air collision about 50 to 100 m above the terrain the correct procedure is:

to execute a descending maneuvre. using the reserve parachute. stalling the glider and so clear the contact with the other aircraft.

29. When sucked in a vertically developed cloud the best to do is:

to steer the glider straight into the lightest part of the cloud. to keep circling through the cloud as high as possible and so fly over it. to perform the most effective escape maneuver and try to keep flying against the wind.

30. Your last choice for emergency landing would always be:

a parking. electric wires. water surface.

31. You miscounted the landing approach and need to shorten it. You are 30 m above the ground:

In such altitude is best to make a 360 turn. By pulling tips of the wing via the right lines you can reduce the effective surface of the wing and glide under a better angle to the ground. By flying in figure eight or S turns you loose hight before the final glide.

32. If I stall the glider:

I use the reserve parachute; if there is not enough hight, I release the steering quickly. I use the reserve parachute; if there is not enough hight, I hold the steering down firmly. I release the steering continuously.

33. 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.

34. In G class airspace there is:

a request of permanent two way connection. a request of connection for flights above 150 m AGL. no request of connection.

35. The AGL abbreviation by a height data in the airspace map means:

the hight above the see level. the hight according the local atmospheric pressure. the hight above the ground level.

36. The paraglider canopy is damaged mostly by:

mice and other wild rodents. storage in dark and dry rooms. UV rays, mechanical abrasion and humidity.

40. Can I meet an airliner in Class E airspace?

No. Only in clouds. Yes.

41. Initial examination includes:

fast check of the afflicted „from head to toe” with emphasis on injury signs. vital functions check according to the chart A-B-C. finding the circumstances of the incident, the patient's problems and possible diseases which he is suffering.

42. Risers are:

up-going thermal currents. the webbings which connect a glider's suspension lines to a pilot's harness. pilots who get up early.

43. A layperson without special training is performing resuscitation:

by chest compressions and artificial respiration in ratio 30:2. by chest compressions only. by chest compressions and artificial respiration in ratio 15:2.

44. Choose the true statement about using the thermal („space”) blanket:

The foil is a very good thermal isolation but does not protect against moisture - it can leak in strong rain. The side doesn’t matter, the important is to wrap it tightly all around the patient. This blanket can be also used as a tourniquet or improvised bandage.

45. An afflicted suddenly collapsed during the ascent of the hill, he is lying down not moving, takes a deep breath about once in twenty seconds. Another witness of the incident tries to feel pulse on his neck and reports weak and rapid pulse. It is necessary to call for help immediately and:

Turn the afflicted into a stabilized position because there is a risk of vomit aspiration. Initiate artificial respiration because this breathing frequency is too low. Indirect heart massage is not needed because there are heartbeats and massage might damage lungs. Initiate resuscitation. So called "gasping breaths" are typical of sudden cardiac arrest. Pulse palpation by layman is unreliable and is not used for large number of errors - the first aider can feel his own heartbeat.

46. Choose the true statement about tactics when you are a witness of a severe injury:

First, you need to restore vital functions as quickly as possible, and only then deal with calling for help. Before calling an emergency service it is appropriate to make at least indicative examination where the accident happened, what happened and how many affected there are. If we witness an accident, we call emergency service after a thorough examination, to make sure that the situation is really serious.

47. A paraglider in a spin fell nearby. On our approach he lies on his back, unconscious, not breathing, bluish. No clearly visible injury is obvious. We'll call an ambulance and firstly:

free the airway by backward head tilt. lay the afflicted in the stabilized position. lay the afflicted in the anti-shock position with head underlaid.

48. In practice, we can recognize the malfunction of blood stream (cardiac arrest) by the fact that:

we cannot feel the pulse at the carotid artery. we cannot feel the heart beating on the chest. the afflicted is unresponsive, does not breath or does only gasping breaths and does not move.

49. "Gasping breaths" mean:

noticeably noisy breaths in fast pace; these breaths are typical for developing shock-like state. individual breaths in noticeably long intervals by the unconscious afflicted; these breaths are typical for cardiac arrest. noticeably fast but quiet and shallow breathing, typical for a patient with an airway obstruction.

50. The helmet of the afflicted:

must never be taken off. should be taken off by pulling in the long axis of the body with permanent fixation of the head and neck. should be taken off only by gente tilting nad twisting.
