Test - PL A

1. When the surface load changes the glide ratio:

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

2. The lift coefficient is influenced the most by:

the air foil curving. the air foil thickness. the speed of flow.

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

No. Only for tail wind. Yes.

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

overpressure. no pressure. negative pressure.

5. There are aerodynamic forces generated on a body in flow. They are called:

the resultant aerodynamic force which is sum of lift and drag. lift and overpressure. lift, mass and drag.

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. 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).

7. Surface load:

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

8. Induced drag:

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

9. Stationary front is the one that:

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

15. The beginning of thunder storm is characterized by:

frequent lightning. persistent ascending currents. rain on the earth's surface.

the same when flying in no wind or exactly against the wind or with the wind. always the same. the same when flying in no wind or with the wind exactly from left or right.

17. When entering a thermal current:

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

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

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. at the top of the mountain.

19. So called escaping maneuvers include:

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

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

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

21. What does the term „spin” mean?

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

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

declination. negative hight, so called dephtines. alitude.

23. Time of sunrise and sunset varies:

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

24. Terrain formations such as forests, meadows, lakes, castles, roads, railways etc. are called:

map projections. topographic area. topographic situation.

25. The earth axix is a line intersecting the center of the earth perpendicularly to the equator. The points where this line intersects the earth surface are called poles and they are:

the geological poles. the marine poles. the magnetic poles.

26. An aircraft on bearing 265 in a wind 085 is flying:

against the wind. perpendicularly to the wind from left. with the wind.

27. 10 cm in map with 1 : 200 000 scale refers of real distance:

50 km 200 km 20 km

28. Your last choice for emergency landing would always be:

electric wires. a parking. water surface.

29. If I stall the glider:

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

30. 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.

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

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

32. After a tall tree landing:

you should climb down as fast as possible to show that you are OK. 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.

33. For emergency landing You would prefer:

water. buildings. trees.

34. 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.

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

These conditions must not be changed. 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.

36. What is it CTR?

Control zone of an airport. An air space where VFR flights are forbidden. Terminal controlled area.

Yes. Only in clouds. No.

40. VFR flights in C, D and E classes airspace may be carried out at a distance from clouds:

outside the clouds and in visibility of ground. only the first at the cloud base pilot can fly in into the cloud. at least 1500 m horizontally and 300 m vertically.

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:

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

43. Fractures of lower limbs are preferably fixed by:

tightening to the other limb (only if that is not broken too). hanging in a triangular bandage. using an improvised splint (branch, stick, etc.).

44. Chest compression during resuscitation is performed:

by the lower end of chest bone. in the middle of chest bone. next to left nipple.

45. Resuscitation without artificial respiration is performed:

by chest compression at rate of about 100 times per minute; instead of artificial breath there is a break after every 30 compressions for 5 seconds. by chest compression at rate of about 60 times per minute so that resultant minute rate would be the same as there was also the artificial respiration. by continuous chest compression at rate of about 100 times per minute.

46. If one layer of pressure bandage is not enough to stop bleeding from a wound on leg:

We apply another 1 or 2 layers or, if still not enough, use a tourniquet. We take off the old bandage and apply a new one and tighten it better. We urge the arrival of emergency services and re-emphasize the urgency of the case.

47. Choose the true statement about using the thermal („space”) blanket:

The foil is a very good thermal isolation but does not protect against moisture - it can leak in strong rain. The side doesn’t matter, the important is to wrap it tightly all around the patient. This blanket can be also used as a tourniquet or improvised bandage.

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

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

49. 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 person actively takes some position, we do not prevent it. 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.
