Test - PL A

1. Turning of a paraglider is the result of:

changes in the distribution of aerodynamic forces on one half of the canopy. changes of the size of projected area of the canopy. changes in the distribution of aerodynamic forces on the canopy.

2. The separation of streamlines is when:

turbulent flow around the upper surface of the wing switches to laminar flow. the streamlines leave the aerofoil after copying its shape. the airflow becomes detached from the surface of the aerofoil.

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

increases. stays the same. decreases.

4. The aerodynamic drag is a sum of:

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

5. 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.

6. The centre of gravity of an aircraft:

is a point where the resultant aerodynamic force acts. is a point where the resultant aerodynamic force and force of gravity acts. is a point where the force of gravity acts.

7. When a paraglider is in steady flight in an ideal environment (no wind) at a glide ratio 6, then it means that:

it is flying at the speed of 6 m/s and the lift of the paraglider is 6 times greater then its drag. the lift of the paraglider is 6 times less then its drag. the lift is 6 times greater then the drag.

8. The main cause of the stall is always:

the start of transition of laminar flow into turbulent flow on the surface of the glider. exceeding the critical angle of attack. decreasing the flight speed under the minimum forward ground speed in a steady flight.

9. An aircraft is flying at a very warm day across the Alps. The weather is good and there is an anticyclone in the area. The aircraft is flying by a mountain at the hight of its summit. What value is the altimeter showing compared to the summit altitude?

The same height as the summit altitude. A higher height than the summit altitude. A lower height than the summit altitude.

10. Which of the following types of cloud is considered low level cloud?

Ns St As

11. Coriolis force acting on the wind is:

inertia force causing bodies movement deflection, thus also the air flow. the centrifugal force. the friction force.

12. Thermal turbulence originates:

in a hilly terrain. in air heated by the ground in unstable air conditions. in uneven heating of the Earth surface.

13. The character of precipitation falling out of Cb - cumulonimbus type clouds is:

persistent rainfall. strong showers. drizzle.

14. Frontal fog forms usually on:

stationary fronts. II. type cold fronts. worm fronts.

15. What are the characteristic signs of the weather on the leeward side of the mountains during Fohn?

Few clouds, unusual increase of temperature, low humidity, often strong winds. Overcast, precipitation, good visibility. Variable cloudiness and occasional rain, moderate or no wind.

16. Spiral is performed by:

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. 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.

17. The take off direction and place choice is subject to:

the wind reported by the nearest meteorological station. the wind at the take off considering the wind direction above the mountain ridge. the wind in the valley by the landing zone.

18. 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.

19. 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.

20. When entering a thermal current:

the glider informs the pilot by its movements about the strength of the lift and usually also about which direction is better to turn. the canopy always tends to collapse and therefore the pilot must brake. the glider usually tends to collapse and therefore the pilot should break a bit before turning.

21. 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.

London. Moscow. Paris.

25. 10 cm in map with 1 : 200 000 scale refers of real distance:

20 km 50 km 200 km

26. The prime meridian is:

meridian, also called the base meridian, passing through Greenwich Observatory in England. the meridian, at which the latitude and longitude equal 0. a meridian not passing through observatory in Greenwich, but only a small circle.

27. Geographical meridian is:

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

28. 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.

29. 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 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.

30. A glider with an asymmetric collapse tends to:

fall quickly and therefore it is necessary to prevent such situations at any cost. fly on, but pilots tend to do unwise piloting inputs. turn rapidly to the side with the collapse and then rotate or slowly return into straight flight.

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. If the steering line brakes, the correct procedure is:

steering via weight shift and cautious pulling of the rear risers. turning only in the side where the steering line is OK. steering by another suitable line and the other steering line or, if there is enough hight, use the reserve parachute.

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

34. The aircraft must not fly at such a distance from other aircraft that would:

be less then 150m. create a collision hazard. restrict the other aircraft.

35. Airport operations are:

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

36. To indicate the height after passing through the transition altitude the setting goes from QNH values:

to the altimeter setting at QFE of the target airport and vertical positions of the aircraft are expressed in hight over the target airport. to the altimeter setting at QFE and vertical positions of the aircraft are expressed as hight above the ground. to the altimeter setting at the value of 1013.2 hPa and vertical positions of the aircraft are expressed in flight levels.

37. The minimum age of student for beginning of theoretical and practical paragliding training in the Czech Republic is:

14 years with the consent of his legal guardians. 15 years with the consent of his legal guardians. 16 years with the consent of his legal guardians.

38. The definition of visibility is:

the ability to see forward from the cockpit of the aircraft in flight determined by meteorological conditions and expressed in units of distance. the ability to see and recognize outstanding unlighted objects by day and lights at night from the cockpit of the aircraft in flight. the ability to see and recognize outstanding unlighted objects by day and lights at night determined by atmospheric conditions and expressed in units of distance.

39. The pilot of the aircraft not equipped with a radio intending to arrive or leave an uncontrolled airport should:

coordinate in advance their arrival or departure with the AFIS unit or the aerodrome operator. observe, for the departure or arrival, the avoidance rules. coordinate in advance their arrival or departure with the airfield owner.

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

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

41. Initial examination includes:

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. fast check of the afflicted „from head to toe” with emphasis on injury signs.

42. Risers are:

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

43. After applying tourniquet the wound is still bleeding:

We need to use another compress bandage. Loosen the tourniquet and lift the afflicted limb up. The tourniquet needs tightening.

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

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

45. If the arrival of a rescue helicopter is expected, rescuers on the ground should stand so that:

they were evenly distributed around the expected landing site and they could prevent potential arrival of other persons. they were always in the visual field of the helicopter pilot. they were in the best possible place for a landing; just before touchdown they move in front of the helicopter.

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

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. 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. 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.

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

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

49. 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.).

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

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