Test - PL A

1. What will be the change of flow speed and static air pressure in a place where the streamline density increases?

The speed will increase, the static pressure will decrease. The speed will decrease, the static pressure will decrease. The speed will increase, the static pressure will increase.

2. Lift arises when an aerofoil is in flow due to the creation of a pressure differential above and below the aerofoil. What is the pressure below and above the aerofoil and what is the ratio of their sizes at normal angles of attack?

There is overpressure below the aerofoil and negative pressure above the aerofoil in the ratio of 1/3 of overpressure and 2/3 of negative pressure. There is overpressure below the aerofoil and negative pressure above the aerofoil in the ratio of 1/3 of overpressure and 2/3 of negative pressure.

3. The paraglider glide ratio is defined as:

the ratio between the horizontal and vertical velocity component of the paraglider. the weight and lift ratio. the relation between the glider performance and vertical speed.

4. A paraglider stall occures when:

the speed system is pushed too fast. the glider overcomes the pilot when taking off. the pilot breaks too much.

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

stays the same. increases. decreases.

6. Glide ratio is influenced only by:

total weight. the velocity of flow. the angle of attack (i.e. lift and drag coefficients).

the wing arrow and air foil thickness. aspect ratio and favorable wing tip shape. the air foil thickness and special

9. When climbing through the transition altitude the altimeter setting is changed. If the local QNH is 1023 hPa, what will happen to the altimeter data?

It will decrease. It will increase. It will not be affected.

10. The main cause of atmospheric convection is:

the day and night temperature difference. sufficient air heating on the earth's surface during unstable stratification. uneven heating of the earth's surface of different colors.

11. Increasing distance between isobars means that in the given area the air velocity will be:

slower. faster. the distance between isobars tells nothing about the air velocity.

12. What weather conditions are expected in temperate latitudes over land in summer in the middle of a stationary area of high pressure?

Ns clouds. Weak winds, haze. Thunderstorms, clear air and strong winds.

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

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

14. The basic cause of mechanical turbulence is:

wind and configuration of terrain. the air mass humidity and temperature. the air mass stratification.

18. How many items is there in the pre start check?

Five. Seven. Three.

19. An asymmetric collapse of about 1/2 of the leading edge should be solved by:

weight shift into the non collapsed side and light break of the same side to keep the glider in straight flight. weight shift into the collapsed side and light break of the non collapsed side to keep the glider in straight flight. no inputs in steering letting the glider reinflate.

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

Positions of gliders on the ground which landed earlier. Grass waves, smoke, tree shaking, moving dust or other light objects in the air. Circling of birds of prey, direction of cloud shades movement and waves on water surfaces.

25. Magnetic north is a direction given by:

the theoretical line intersecting the earth center and the surface of the earth in points called magnetic north and magnetic south. the compass needle free of any interferences. measurements on a map.

26. The globe is:

a rotating ellipsoid flattened at the poles. ideal sphere. a net of coordinate lines.

28. Use the reserve parachute without hesitating:

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

29. When flying on speed system:

The paraglider will increase its speed and it will be more stabile thanks to better flow. The paraglider is prone to symmetrical or asymmetrical collapses. The paraglider will increase its speed and will be more prone to symmetrical or asymmetrical collapses.

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

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. In such altitude is best to make a 360 turn.

31. During flight a pilot should have his cellphone (if it is available):

in any place, because he cannot telephone during flight anyway. in the back harness pocket so it could not break or harm the pilot in case of accident. in a place, where he can reach it by any hand from the flying position.

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

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

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

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. to turn the glider against the wind.

34. Restricted air space (LK R):

must be passed through. can be passed through under specified conditions. must not be passed through.

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

Yes. Only in clouds. No.

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

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

43. "Secondary examination" of an injury afflicted means:

the second (and next) control examination to determine if there is a deterioration in the status. an inspection of afflicted "head to toe" in order to uncover any injury changes on body. an examination by another independent person to verify the initial conclusions.

44. 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.

45. If it is obvious that the action of rescue helicopter is necessary, in the Czech Republic it is preferably needed to call number:

1210 112 155

46. Fractures of lower limbs are preferably fixed by:

tightening to the other limb (only if that is not broken too). using an improvised splint (branch, stick, etc.). hanging in a triangular bandage.

47. For the quality of resuscitation, the most crucial is:

the highest possible frequency of compressions. the deepest compressions. timely starting and continuity of compressions.

48. If the unconscious afflicted is not breathing:

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

49. Resuscitation without artificial respiration is performed:

by continuous chest compression at rate of about 100 times per minute. by chest compression at rate of about 100 times per minute; instead of artificial breath there is a break after every 30 compressions for 5 seconds. by chest compression at rate of about 60 times per minute so that resultant minute rate would be the same as there was also the artificial respiration.

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

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