Test - PL A

1. 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 drag coefficient drops abruptly. the lift coefficient sharply increases.

2. The dynamic stability of a paraglider means:

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

3. What kind of change of flow speed and static pressure causes the widening of streamlines in a specified place?

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

4. Can we read the best glide ratio speed in front wind from the polar line?

No. Only for tail wind. Yes.

5. 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.

6. Induced drag:

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. arises as a result of interference between flows around different parts of an aircraft.

7. On the bottom side of the wing in flight there is:

overpressure. no pressure. negative pressure.

8. A paraglider stall occures when:

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

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

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

10. Dangerous storm phenomena are:

strong updrafts and hight of the Cb could. the density of the Cb cloud which consists of liquid and solid state of water. strong updrafts with maximums in the upper half of CB cloud, stong turbulence, strong downdrafts with maximums near the CB cloudbase, frosts, electric characteristics of the Cb cloud.

12. The boundary between troposphere and stratosphere is called:

tropopause atmosphere ionosphere

13. In the northern hemisphere by proceeding vertically from the ground, the wind direction is somewhat different from the direction measured at the ground and it turns:

right. It doesn’t turn. left.

14. Vertical robustness of the troposphere is the greatest:

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

16. So called escaping maneuvers include:

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

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

at the top of the mountain. 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.

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

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

19. B-stall is performed by:

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

20. 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.

21. 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.

22. The flight velocity displayed by GPS is:

true air speed. indicated air speed. ground speed.

23. 045 degrees is direction:

north west. north east. south west.

24. The location of geographical and magnetic poles is:

27. Geographical meridian is:

a half of meridian circle. a segment of a circle whose plane is perpendicular to the earth's axis. a circle around the globe.

28. 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.

29. After an asymmetric collapse the correct procedure is:

no sudden piloting inputs; a certified paraglider will return into straight flight itself. 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.

30. If one side of canopy is stalled, the pilot should:

hold down the already pulled steering and counter-steer the rotation by weight-shift. pull the second steering fully and then release both. release the steering continuously.

31. After a tall tree landing:

you should do maximum via reachable means to get professional rescue help (a cellphone or radio call, waiting for friends, whistle ect.) you should wait until your friends come and then you climb down while they are ready to catch you if needed. you should climb down as fast as possible to show that you are OK.

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

in a place, where he can reach it by any hand from the flying position. 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.

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

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

34. An aircraft having priority must maintain its course and speed:

The course must be kept but speed can be changed. This rule does not relieve the aircraft commander of responsibility to carry out such measures that will the best prevent a collision. These conditions must not be changed.

35. The pilot (aircraft commander) is in competence to:

The pilot has no right to decide on the execution of a flight. to decide definitively on the execution of a flight. to obey an operator's decision on the execution of a flight.

36. Responsibility of the pilot (commander) of the aircraft:

The aircraft commander is responsible for execution of the flight under the rules of flying, let he alone controls the plane or not, except in cases when circumstances force a deviation from these rules in the interest of safety. The aircraft commander has not the right to take a final decision on the execution of the flight. The aircraft commander is not responsible for the execution of the flight when he received takeoff clearance from air traffic control services.

37. After landing at the airport, the altimeter set to the airport QFE indicates:

0. the airport altitude AMSL. the airport altitude in standard atmosphere.

38. A proof of liability insurance must be on board during all flights.

Yes. Not during an airport flight. No.

39. Who is authorized to check a pilot's license or student document?

Paragliding operations inspector of LAA CR, person authorized of Ministry of Transport, Czech Police or local municipal authority personnel.

40. Except for takeoff or landing or except by permission issued by the Authority a VFR flight must be conducted above the ground or water at a height of not less than:

150 m 300 m 150 m except for ridge soaring.

41. A paraglider is the most damaged by:

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

42. 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.

43. During an improvised transport of an unconscious afflicted:

caution is not important because the unconscious afflicted doesn’t feel pain anyway. the process should be as fast as possible. special attention should be payed to caution and head fixation.

44. 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:

put the afflicted in a semi sitting position, pull out the sherd and apply compressing bandage. 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. lay the afflicted down on his back with legs lifted, apply a tourniquet on his forearm tightening it gently. We do not pull out the piece of glass on principle.

45. Fractures of upper limbs are preferably fixed by:

hanging in a triangular bandage. tightening to the body in extended position. using an improvised splint (branch, stick, etc.).

46. A foreign object (e.g. little stone, sherd or so):

must be removed even if surrounding tissue is damaged and then the wound needs rinsing with disinfection. is to be removed from a wound if it is possible without excessive violence (e.g. rinsing with water, gently pulling etc.). is never to be removed - cover the wound with anything in it and soak the bandage with disinfection.

47. The best way of use of the „anti-shock” foil (thermal blanket) is:

The afflicted is carefully covered with it. The afflicted is tightly wraped into it including head, only face is uncovered. It is laid under the afflicted.

48. If the unconscious afflicted is not breathing:

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

49. The telephone number of medical emergency service in the Czech Republic is:

155 158 150

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

If the afflicted is communicating he should always be placed into position on the side (the "stabilized" or "recovery" position). 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 person actively takes some position, we do not prevent it.
