Test - PL A

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

2. When increasing the angle of attack:

the lift coefficient and drag coefficient decrease. the lift coefficient and drag coefficient increase. the lift coefficient increases and drag coefficient decreases.

3. At minimum speed:

4. The chord is:

the curve that is halfway between the upper and lower surfaces of the aerofoil. the straight line dividing the aerofoil in the middle of its thickness into two equal parts. the imaginary straight line joining the leading and trailing edges of the aerofoil.

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

6. The lift on the aerofoil is created by:

densification of streamlines above the aerofoil, the top surface of the aerofoil thus generates a negative pressure; below the aerofoil the streamlines expand and thereby an overpressure occurs beneath the aerofoil. the force of flowing air from front of the aerofoil (when the angel of attack is positive). densification of streamlines below the aerofoil, the lower surface of the aerofoil thus generates a negative pressure; above the aerofoil the streamlines expand and thereby an overpressure occurs above the aerofoil.

7. The angle of attack is:

the angle between the aerofoil’s chord and the oncoming flow. the angle between the oncoming flow and the horizon line. the angle between aerofoil’s chord and the horizon line.

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

decreases. stays the same. increases.

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

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

13. 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. High pressure and temperature drop. Drop of cloud base, sometimes even to the ground.

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

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

15. Clouds in troposphere form from:

Oxygen. water vapor. Nitrogen.

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

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. Positions of gliders on the ground which landed earlier.

17. When entering a thermal current:

the canopy shoots forward and can collapse. the canopy lilts backwards and can shoot forward afterwards. the canopy tilts sidewards and can get asymmetric collapse.

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

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

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

20. 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.

21. 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.

22. The location of geographical and magnetic poles is:

28. Use the reserve parachute without hesitating:

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

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. The best when blown behind a ridge is: Při přefouknutí přes kopec je nejbezpečnější

to fly with the wind as far as possible to a possible emergency landing field. to do big ears which will help to fly through turbulences by increasing surface load of the wing. to use a reserve parachute which is more stable in turbulences.

31. 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.

32. If during a flight the reserve parachute drops out accidentally and opens:

I should collapse the rescue parachute by pulling its lines. I should try to collapse the glider canopy by pulling rear risers or steering to minimise its influence into reserve parachute flight and I should get prepared for landing. I prepare for the landing on the rescue, nothing else can be done anyway.

33. During ground handling training the glider lifts the pilot above the ground in a wind gust unexpectedly. The correct procedure is:

to release the steering and fly, steer and land back to the ground. to pull and release the steering repeatedly and by such flapping go back to the ground. to pull the steering fully.

34. Airport operations are:

all flying aircrafts and aircrafts on the aerodrome operational area. all traffic at the aerodrome area and all aircrafts flying in the vicinity of the airport. all vehicles and persons operations on the aerodrome area.

35. A pilot must always have:

a pilot's license or a student document, the airworthiness certificate, a proof of insurance for damage caused the aircraft operation, medical certificate of flying eligibility. a proof of identity, a pilot's license or a student document, the airworthiness certificate, a proof of insurance for damage caused the aircraft operation, medical certificate of flying eligibility. a proof of identity, a pilot's license or a student document, the technical certificate of the aircraft, a proof of insurance for damage caused by the aircraft operation.

a pilot who holds a valid assessment on medical fitness or a student pilot under the conditions laid down in the training curriculum. a pilot who holds a valid pilot license with the appropriate qualifications or a student pilot under the conditions laid down in the training curriculum. a pilot who holds a valid pilot license with the appropriate qualifications or a person authorized by the light aircraft operator in the presence of the pilot, or a student pilot under the conditions laid down in the training curriculum.

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

Not during an airport flight. Yes. No.

40. In G class airspace there is:

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

41. A paraglider is the most damaged by:

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

42. 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.

43. "Gasping breaths" mean:

individual breaths in noticeably long intervals by the unconscious afflicted; these breaths are typical for cardiac arrest. noticeably fast but quiet and shallow breathing, typical for a patient with an airway obstruction. noticeably noisy breaths in fast pace; these breaths are typical for developing shock-like state.

44. The helmet of the afflicted:

must never be taken off. should be taken off only by gente tilting nad twisting. should be taken off by pulling in the long axis of the body with permanent fixation of the head and neck.

45. 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.

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

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. 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.

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

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

48. When stopping bleeding by tourniquet, the principle is:

„If using tourniquet, then properly.“ „The tourniquet must not hurt.“ „The tourniquet must hurt.“

49. 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 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. 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.

50. To prevent heat loss the most effective is:

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