Test - PL A

1. When a paraglider is in steady flight in an ideal environment (no wind) at a glide ratio 6, then it means that:

the lift is 6 times greater then the drag. the lift of the paraglider is 6 times less then its drag. it is flying at the speed of 6 m/s and the lift of the paraglider is 6 times greater then its drag.

2. When air flow is laminar:

there is a relative mix of streamlines. there is a relative mix of streamlines but at the end of given aerofoil there are no significant eddies in the flow. there is no relative mix of streamlines.

3. In a steady gliding flight there is a balance between:

gravity force and lift plus drag. lift and drag. thrust and weight, drag and lift.

4. Bringing a paraglider close to the critical angle of attack is manifested by:

significant rise of forces in steering lines. sudden increase of descent rate. decrease of steering forces.

5. If the pilot weight increases, the wing glide ratio:

stays the same. increases. decreases.

6. At the critical angle of attack:

the lift coefficient reaches its maximum values, over further increasing of the angle of attack the lift coefficient decreases abruptly. the lift coefficient sharply increases. the drag coefficient drops abruptly.

7. Surface load:

indicates the number of kilograms of the total weight per m2 of bearing area. indicates the number of kilograms of the pilot weight per m2 of bearing area. indicates the number of m2 of bearing area per one kilogram of the total weight.

8. If the angle of attack increases, the forward speed:

stays the same. decreases. increases.

9. The greatest concentration of condensation nuclei is:

above oceans. near large urban areas (industrial areas). above mountains.

10. Convective activity in the mid-latitudes is the greatest:

in winter at midday. in summer at midday. at noon.

11. Which of the phenomena occurring on the II. kind cold front are particularly dangerous for low-flying aircraft?

Strong turbulence limited to the narrow space of vortex - the microburst, with axis approximately at the base of Cb - cumulonimbus cloud. Drop of cloud base, sometimes even to the ground. High pressure and temperature drop.

12. Mass storms occur:

anytime. mostly during the night. mostly in the afternoon and evening in the hours of the highest ground temperatures.

13. The low pressure system - Cyclone - is the area:

of low atmospheric pressure with the minimum value on its bordes. of low atmospheric pressure with the minimum value in its middle. where the atmospheric pressure is decreasing outwards.

14. The boundary between troposphere and stratosphere is called:

atmosphere ionosphere tropopause

15. In the definition of standard atmosphere the pressure and temperature values at mean sea level are:

1013,25 hPa, 0°C 1013,25 hPa, +15°C 1015 hPa, +10°C

16. The heading of aircraft and its direction of movement compare to ground is:

the same when flying in no wind or exactly against the wind or with the wind. always the same. the same when flying in no wind or with the wind exactly from left or right.

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

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

18. I increase the flight speed by:

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

19. When entering a downdraft:

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

20. When entering a thermal current:

the canopy always tends to collapse and therefore the pilot must brake. 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 glider usually tends to collapse and therefore the pilot should break a bit before turning.

21. By releasing the speed system the flight speed is:

increased. decreased. unaffected; only the angle of attack increases.

22. Comparative navigation involves:

comparing the calculated times with the reality. comparison of data of navigation devices (GPS) with a map. comparing terrain with a map and vice versa.

23. Sooner then in Prague, the sun rises in:

London. Moscow. Paris.

24. Geographic coordinates indicate:

certain place name. certain geographical location. time zone position.

25. 045 degrees is direction:

south west. north east. north west.

26. Which of the following conditions is the most important for comparative navigation?

Experience of the pilot and his estimation. Navigational preparation before flight, map, visibility of ground. A good map and navigation skills of the pilot.

27. When performing comparative orientation it is always more reliable:

to carefully view the terrain below the aircraft. to focus on one landmark. to locate and identify several landmarks.

28. A glider with an asymmetric collapse tends to:

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

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

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

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

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

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

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. He should keep flying against the wind and emergency-land in the terrain below him.

32. Your special equipment for safety maneuvers training should be:

a life jacket, a hook knife for cutting lines or risers. a life jacket, an orange helmet and light shoes. a life jacket and a flare.

33. Use the reserve parachute without hesitating:

under a Cumulonimbus cloud. after being blown behind a mountain ridge. in rapid uncontrolable rotation.

34. When two light aircrafts are flying on intersecting tracks in free space, the right of way is of the light aircraft flying:

from the right. from the left. against the sun.

35. If two aircrafts are flying on lines facing each other or approximately such, each of them should give way by changing its course to the:

right. side which is more suitable for avoiding a crash. left.

36. The aircraft, that is obliged by the rules to give way to another aircraft, must:

avoided so that the maintained horizontal distance between aircrafts was 300 m. avoid by flying above or under or cross the other aircraft flight line at a sufficient distance. avoided so that the maintained vertical distance between aircrafts was 150 m.

37. An aircraft in flight or moving on the ground must give way to the aircraft:

which has no connection with the air traffic control cervices. which received permission for landing approach. which is landing or in the final approach to the landing.

38. VFR flights in C, D and E classes airspace may be carried out at a distance from clouds:

outside the clouds and in visibility of ground. only the first at the cloud base pilot can fly in into the cloud. at least 1500 m horizontally and 300 m vertically.

39. Two of the same category aircrafts are flying in one track against each other. Na vstřícné trati letí letadla stejné kategorie. Actions of avoidance are:

Both aircrafts will change their curse to the right. You will turn to the right, the other aircraft will turn to the left. Both aircrafts will change their curse to the left.

40. A Czech Pilot license holder can obtain a Sport Pilot license after:

six months. five months. nine months.

41. Initial examination includes:

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

42. A paraglider is the most damaged by:

sun and wrong packing. winch tow flying, powered paragliding and operation on wet grass. UV rays, wet storage and abrasion.

43. 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 anti-shock position with head underlaid. lay the afflicted in the stabilized position.

44. Unless prevented by special circumstances, the best for the accident afflicted is:

a position on the side („stabilized” or „recovery” position). the "Anti-shock" position with legs and arms raised as high as possible„ a position that the afflicted person wants to take.

45. Signal to perform by a person on the ground to cancel the need of rescue helicopter landing is:

to stand with one arm up and second arm along the body (a paraphrase of the letter N). to stand and rhythmically move arms up and down wit palms turned upwards. to wave by any object of red color.

46. Choose the true statement about heat loss after an injury:

Maintaining body temperature is one of the most energy-intensive vital processes. Fight against heat loss therefore belongs - especially with severe injuries - amongst life-saving acts with high priority. Mild hypothermia is in terms of first aid advantageous because it inhibits the metabolic processes and thus slows the onset of shock. Severe and prolonged hypothermia is harmful, preventing heat loss is therefore of particular importance for injuries in the winter and in poorly accessible terrain. Preventing heat loss is especially important because possible hypothermia is unpleasant and stressful for the afflicted. But this is not the priority for first aid.

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

If we witness an accident, we call emergency service after a thorough examination, to make sure that the situation is really serious. 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. First, you need to restore vital functions as quickly as possible, and only then deal with calling for help.

48. If the unconscious afflicted is not breathing:

We promptly transport him to the professional medical service. We start the resuscitation immediately. First we try to free the airway.

49. Choose the true statement about a position of a serious injury afflicted:

If the afflicted person actively takes some position, we do not prevent it. If the afflicted is unconscious, he should always be placed in "anti-shock" position with legs and arms raised as high as possible to restore blood flow to the brain. If the afflicted is communicating he should always be placed into position on the side (the "stabilized" or "recovery" position).

50. Choose the true statement about the obligation to provide first aid:

If there is serious injury, everybody is obliged to provide first aid; this assistance must not endanger the life or health of the firstaider. The obligation to provide first aid is only moral and it is not legally enforceable. Everyone who witnesses an accident is obliged to provide first aid, regardless of the severity of injury and danger.
