Test - PL A

1. When air flow is laminar:

there is a relative mix of streamlines. there is no 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.

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

increases. decreases. does not change.

3. 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.

4. Where on the aerofoil the flow separation starts?

In the boundary layer at the suction side of the aerofoil from the trailing edge end. In the boundary layer at the suction side of the aerofoil from the leading edge end. In the wake on the suction side of the aerofoil from the leading edge end.

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

overpressure. negative pressure. no pressure.

6. Induced drag:

arises as a result of interference between flows around different parts of an aircraft. arises as a result of parasitic energy induced by air rfiction around 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.

7. Which of the following pilot inputs increases the angle of attack?

Pulling the steering. Pushing the speed system. Releasing the steering.

8. When the surface load changes the glide ratio:

changes because the relation between lift and drag does not change. changes because effective bearing area is the same. does not change because the relation between lift coefficient and drag coefficient does not change.

9. The air mass is called unstable if there are:

stratified clouds in it. inversions in it. convective vertical motions in it.

10. The decrease of temperature with altitude in a standard atmosphere definition - vertical temperature gradient - has a value of:

1,0° C / 100 m. 0,6° C / 100 m. 0,65° C / 100 m.

11. Low level cloud can be:

St – stratus Ac – altocumulus Ci – cirrus

12. Local isolated thunderstorms are mostly:

frontal air lift (warm front). mass storms. frontal air lift (cold front).

13. The change of physical state ice - water vapor is called:

sublimation evaporation condensation

14. Stationary front is the one that:

is moving only clockwise. is not moving or moves very slowly. is moving in leaps.

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. By releasing the speed system the flight speed is:

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

17. 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 at its windward side turning 180° into the wind at the turn points. we fly alongside a slope just above its lee side turning 180° into the wind at the turn points which means against the slope.

18. When entering a downdraft:

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

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

no inputs in steering letting the glider reinflate. 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.

26. Contour lines are curves connecting points of the same:

alitude. declination. negative hight, so called dephtines.

27. 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.

28. The reserve parachute is used so that:

Pull the rezerve parachute handle; when the needles are torn out, the reserve parachute opening system is activated. By pulling the handle the reserve parachute is activated; the handle can be lost. Pull the reserve parachute from the harness and throw it into a free space letting go the handle too.

29. If a pilot is being dragged by strong wind along the ground, he should:

wait until the glider stops itself. pull the A risers or lines. pull the steering lines or rear lines/risers.

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

to turn the glider against the wind. 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.

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

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

32. 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.

33. After an asymmetric collapse the correct procedure is:

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 no sudden piloting inputs; a certified paraglider will return into straight flight itself. pulling the steering on the not collapsed side quickly and fully to help the regeneration of the canopy.

34. In G class airspace there is:

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

35. LAA regulation, which governs the rules of flying a paraglider in the Czech Republic is called:

ZL - 3 ZL - 1 PL - 2

36. A Czech paraglider technical certificate is issued:

always by a designated Paragliding Operations Inspector of LAA CR. by a producer’s technical inspector for category „P” and by LAA CR for category „Z”. always by a Paragliding Technical Inspector of LAA CR.

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

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. avoided so that the maintained horizontal distance between aircrafts was 300 m.

38. 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. Paragliding operations inspector of LAA CR, Czech Police, Czech CAA inspector, a person authorized by an airport or property owner. Paragliding operations inspector and Paragliding technical inspector of LAA CR, a person authorized by the Ministry of Transport or the CAA of the CR, Czech Police.

39. The lower limit of a control zone (CTR) is formed by:

the ground surface. a specified altitude. the upper limit of the G class air space.

40. To recalculate a figure in meters into figure in feet we use the simplified formula:

(m x 3) : 10 (m x 3) + 10% (m : 10) x 3

41. Risers are:

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

42. A paraglider is the most damaged by:

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

43. „Surgical” rubber gloves:

are suitable for treatment of patients suspected of infectious disease. should be used only in treatment of heavy bleeding or dirty wounds. should be used for taking care of any injury.

44. 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 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. 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.

45. In improvised conditions fracture fixing is:

needed in exceptional cases if manipulation with the patient before professional medical services arrival is necessary. necessary in case of open fracture. a priority first aid objective.

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. "Secondary examination" of an injury afflicted means:

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. the second (and next) control examination to determine if there is a deterioration in the status.

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

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

49. Resuscitation (animation) is needed to be performed if the afflicted:

is unresponsive and there is no pulse on carotid artery (the breathing state is not important). is unresponsive, not moving and not breathing, or only "gasping" breaths are seen. is unresponsive, not moving, regardless of the state of breathing (a layperson is not able to reliably judge the respiratory status).

50. Choose the true statement about a position of an unconscious afflicted:

The unconscious afflicted must not be moved to eliminate the risk of further spine and spinal cord damage. If the afflicted is reliably breathing in the current position, we leave him in this position. The unconscious injury afflicted should always be placed on his back with his head tilted back.
