Test - PL A

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

its velocity is 6 m/s. it will fly 6 km far from the altitude of 1 km. it will fly 1 km far from the altitude of 6 km.

2. 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 equally oriented but smaller then gravity force and that is why the paraglider in steady air always descends. It is oppositely oriented but smaller then gravity force and that is why the paraglider in steady air always descends.

3. 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.

4. 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.

5. Glide ratio is influenced only by:

total weight. the velocity of flow. the angle of attack (i.e. lift and drag coefficients).

6. The lift on the aerofoil is created by:

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. the force of flowing air from front of the aerofoil (when the angel of attack is positive). 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.

7. The aerodynamic drag is a sum of:

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

8. Surface load:

indicates the number of kilograms of the total weight per m2 of bearing area. indicates the number of kilograms of the pilot weight per m2 of bearing area. indicates the number of m2 of bearing area per one kilogram of the total weight.

9. The boundary between troposphere and stratosphere is called:

tropopause ionosphere atmosphere

10. Mass storms occur:

anytime. mostly during the night. mostly in the afternoon and evening in the hours of the highest ground temperatures.

11. A cold front progresses faster than a warm front, the warm sector at the ground level gradually narrows and the warm air in this region is forced up into the higher layers. This process is called:

cyclone extinction. cyclone filling. oclusion.

12. With increasing altitude the wind speed usually:

increases. decreases. increases in the summer and decreases in the winter.

13. Unsaturated adiabatic curve is showing the change in temperature with height of value:

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

17. Ridge soaring is practiced so that:

we fly alongside a slope at its windward side turning 180° into the wind at the turn points. 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.

18. The take off control includes:

the check of glider and harness wear and tear, stitching, carabiners, helmet and instruments. the check of canopy, carabiners, weather and space in the direction of flight and landing. the check of harness, lines, canopy, weather and space.

19. B-stall is performed by:

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

20. What does the term „spin” mean?

Symmetric paragider stall. Asymmetrical (one side) paraglider stall. A spiral.

21. When entering a downdraft:

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

22. Magnetic north is a direction given by:

measurements on a map. the compass needle free of any interferences. the theoretical line intersecting the earth center and the surface of the earth in points called magnetic north and magnetic south.

23. 045 degrees is direction:

north west. north east. south west.

24. Geographic coordinates indicate:

certain place name. certain geographical location. time zone position.

25. The most suitable maps for aeronautical navigation are:

those with precise angles. maps with 1 : 500 000 scale. the maps which truly reflect the topographic situation and angles.

26. Time of sunrise and sunset varies:

with annual periods. influenced by the magnetic field of the Earth. depending on the intensity of sunlight.

27. Geographical North and South:

do not change location. are influenced by the Earth’s magnetism. change location depending on annual periods.

28. For emergency landing a pilot would rather choose:

dense forest. a lonely tree. a forest road.

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 turn the glider against the wind. to jump out of the harness about 3 to 5 m above the water surface.

30. 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.

31. A glider with an asymmetric collapse tends to:

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

32. If I stall the glider:

I release the steering continuously. I use the reserve parachute; if there is not enough hight, I hold the steering down firmly. I use the reserve parachute; if there is not enough hight, I release the steering quickly.

33. For emergency landing You would prefer:

buildings. water. trees.

34. The upper limit of class E airspace is:

FL 95 (2900 m) FL 125 (3800 m) FL 85 (2600 m)

35. A light aircraft can be steered by:

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.

36. An aircraft in flight or moving on the ground must give way to the aircraft:

which is landing or in the final approach to the landing. which received permission for landing approach. which has no connection with the air traffic control cervices.

39. Pilots must have the documents required for flying a light aircraft:

with them at every flight. with them at flights outside the airport. with them at cross country flights.

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

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. The course must be kept but speed can be changed.

41. A paraglider is the most damaged by:

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

42. Risers are:

43. If it is obvious that the action of rescue helicopter is necessary, in the Czech Republic it is preferably needed to call number:

1210 112 155

44. 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.

45. The most effective anti shock precautions in laic first aid (after securing vital functions) are:

fracture fixing, wound and abrasions treatment. thermal comfort, lots of sweet liquids, position on side. convenient position, thermal comfort, calming.

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

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

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

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

48. 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 the anti-shock position with his feet up, cover him and call an ambulance. We lay him in shade into semi sitting position and check him occasionally during flying. If his condition gets worse, we call help. 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.

49. If the unconscious afflicted is not breathing:

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