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:

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

2. What kind of change of flow speed and static pressure causes the widening of streamlines in a specified place?

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

3. The separation of streamlines is when:

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

4. 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.

5. In a normal steady flight:

there is negative pressure on the upper surface and overpressure on the lower surface of the wing. there is overpressure on the upper surface and negative pressure on the lower surface of the wing. there is overpressure on the upper and lower surface of the wing.

6. When the surface load changes the glide ratio:

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

7. Where on the aerofoil the flow separation starts?

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

8. Select the correct statement regarding the position of the unconscious affected with a severe trauma:

The basic rule is not to move the unconscious affected to eliminate the risk of further damage to the spine and spinal cord. An insured unconscious affected person should always be placed in position on her back with her head tilted back. If the affected is in the current position reliably breathing, I leave him in this position.

9. The high pressure - anticyclone - is the area of:

high atmospheric pressure with the highest value on its border. high atmospheric pressure with the highest value in its middle. high atmospheric pressure rising in particular direction.

10. Vertical robustness of the troposphere is the greatest:

over the poles. in the temperate zones. over the equatorial regions.

11. How is relative humidity of air affected by changes in the quantity of water vapor contained in it?

It increases with increasing amounts of water vapor. It is affected only by temperature. It is not affected by water vapour amount changes.

12. In the area of low pressure in the northern hemisphere the wind close to the ground is blowing:

strait into the middle of the low pressure in the whole area. clockwise. counter clockwise.

13. Precipitation coming off St-stratus layer of cloud is mostly:

drizzle. hail. violent torrential rain.

14. Thermal turbulence originates:

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

15. What type of precipitation can be expected on an active cold front?

Drizzle. Showers and thunderstorms. Light persistent rain.

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

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

17. Spiral is performed by:

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

18. The take off control includes:

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

19. 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.

20. 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.

21. When entering a downdraft:

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

22. 10 cm in map with 1 : 200 000 scale refers of real distance:

20 km 50 km 200 km

23. Geographical North and South:

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

24. The globe is:

ideal sphere. a rotating ellipsoid flattened at the poles. a net of coordinate lines.

25. Comparative navigation involves:

comparison of data of navigation devices (GPS) with a map. comparing terrain with a map and vice versa. comparing the calculated times with the reality.

26. The prime meridian is:

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

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

28. 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.

29. You miscounted the landing approach and need to shorten it. You are 30 m above the ground:

In such altitude is best to make a 360 turn. By flying in figure eight or S turns you loose hight before the final glide. 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.

30. A glider with an asymmetric collapse tends to:

fall quickly and therefore it is necessary to prevent such situations at any cost. 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.

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. If one side of canopy is stalled, the pilot should:

release the steering continuously. hold down the already pulled steering and counter-steer the rotation by weight-shift. pull the second steering fully and then release both.

33. In mid-air collision about 50 to 100 m above the terrain the correct procedure is:

using the reserve parachute. stalling the glider and so clear the contact with the other aircraft. to execute a descending maneuvre.

34. Flying above a gathering of people at such a height that would not allow a safe landing in case of danger without endangering pilots or people on the ground is:

forbidden. possible only at an air show with a valid authorization issued. allowed.

35. 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.

36. Except for takeoff or landing or except by permission issued by the Authority a VFR flight must be conducted above the ground or water at a height of not less than:

300 m 150 m 150 m except for ridge soaring.

37. When two light aircrafts are flying on intersecting tracks in free space, the right of way is of the light aircraft flying:

from the left. against the sun. from the right.

38. Verifying whether a paraglider technical certificate is valid is a duty of:

the operator. the head of air traffic. the aircraft commander (pilot).

39. 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.

40. The definition of visibility is:

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. the ability to see forward from the cockpit of the aircraft in flight determined by meteorological conditions and expressed in units of distance.

41. Initial examination includes:

vital functions check according to the chart A-B-C. 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.

42. A paraglider is the most damaged by:

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

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

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

44. During an unsuccessful landing a pilot flew through a window and cut his wrist so badly that the wound is heavily bleeding, blood squirts. 10 cm long piece of broken glass projects from the wound. The afflicted person is conscious, pale, complaining of pain in his right ankle which is evidently deformed. We'll call an ambulance and:

lay the afflicted down on his back with legs lifted, apply a tourniquet on his forearm tightening it gently. We do not pull out the piece of glass on principle. put the afflicted in a semi sitting position, pull out the sherd and apply compressing bandage. fix the leg, lay the afflicted in the anti shock position, lift the wounded hand up and if the bleeding doesn’t stop, apply a compressing bandage.

45. Choose the true statement about improvised transport:

The priority of an improvised transport is speed. Unless it is necessary the patient should not be transported before the arrival of professional assistance. The most important is that the afflicted stays in a slightly inclined position with head down during the whole transport.

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

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. they were evenly distributed around the expected landing site and they could prevent potential arrival of other persons.

47. 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.

48. „Surgical” rubber gloves:

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

49. During an improvised transport of an afflicted:

the limbs should be stretched along the long axis of body. the specific position is not a question but the fact that the afflicted is fixed and the position does not change suddenly. the head should be placed so that it could move in response to terrain unevenness.

50. In practice, we can recognize the malfunction of blood stream (cardiac arrest) by the fact that:

the afflicted is unresponsive, does not breath or does only gasping breaths and does not move. we cannot feel the pulse at the carotid artery. we cannot feel the heart beating on the chest.
