Test - PL A

1. The dynamic stability of a paraglider means:

that it is easy to steer, especially in aerobatics. that if unbalanced it returns into steady flight. that if unbalanced it is not completely returning into steady flight.

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. What size and direction is the resultant aerodynamic force in a steady gliding flight?

It is the same size and of the opposite direction as the gravityy force. It is oppositely oriented but smaller then gravity force and that is why the paraglider in steady air always descends. It is equally oriented but smaller then gravity force and that is why the paraglider in steady air always descends.

4. At the critical angle of attack:

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

5. The aircraft falls when:

it gets over the critical angle of attack. the pilot makes too sharp turn. the aircraft take off weight is higher then maximum allowed.

6. If the pilot weight increases the paraglider or powered paraglider speed:

does not change. decreases. increases.

7. Induced drag:

arises as a result of interference between flows around different parts of an aircraft. arises as a result of air flow from the lower wing surface, around the wingtip, towards the upper wing surface due to a pressure difference. arises as a result of parasitic energy induced by air rfiction around an aircraft.

8. The aerodynamic drag is a sum of:

form drag, friction drag, induced drag and interference drag. parasitic drag and supportive drag. parasitic drag, form drag, interference drag and rolling drag.

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

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

16. When entering a thermal current:

18. I increase the flight speed by:

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

19. Ridge soaring is practiced so that:

we soar the wind wave just above the mountain ridge turning 180° at the turn points no matter what direction. we fly alongside a slope just above its lee side turning 180° into the wind at the turn points which means against the slope. we fly alongside a slope at its windward side turning 180° into the wind at the turn points.

20. Spiral is performed by:

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. weight shift in the intended turning side, pulling the steering on that side and pulling down the front riser on the other side. 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.

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

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

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

to perform the most effective escape maneuver and try to keep flying against the wind. 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.

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

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

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

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

32. When landing in water surface a pilot should steer the glider:

against the wind. with the wind from a side. with the wind.

33. 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. In such altitude is best to make a 360 turn. By flying in figure eight or S turns you loose hight before the final glide.

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

43. A pilot should have his mobile phone:

placed so that it could be reached in any position of pilot’s body. placed in the pocket of the harness so that it could not cause any injury in case of an accident. switched off because the aviation regulations forbid the use of mobile phones in flight.

44. To prevent heat loss the most effective is:

To cover dressed afflicted gently with an "anti-shock" foil. To wrap dressed afflicted tightly in an "anti-shock" foil. To wrap undressed afflicted tightly in an "anti-shock" foil.

47. During an unsuccessful landing a pilot flew through a window and cut his wrist so badly that the wound is heavily bleeding, blood squirts. 10 cm long piece of broken glass projects from the wound. The afflicted person is conscious, pale, complaining of pain in his right ankle which is evidently deformed. We'll call an ambulance and:

fix the leg, lay the afflicted in the anti shock position, lift the wounded hand up and if the bleeding doesn’t stop, apply a compressing bandage. put the afflicted in a semi sitting position, pull out the sherd and apply compressing bandage. lay the afflicted down on his back with legs lifted, apply a tourniquet on his forearm tightening it gently.

49. 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.

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

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