Test - PL A

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

2. At minimum speed:

the paraglider or powered paraglider is close to stall. the paraglider or powered paraglider will fly the longest. the paraglider or powered paraglider will fly the farthest.

3. When increasing the angle of attack:

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

4. 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.

5. Larger part of lift is generated:

above 2/3 of the aerofoil, around 55%. below the aerofoil, around 2/3. above the aerofoil, around 2/3.

6. 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.

7. 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.

8. In the moment of flying in a sinking currant the angle of attack:

decreases. does not change. increases.

9. What will be the surface wind characteristics in the area where on the surface meteorological map there are isobars close together?

Weak wind blowing along the isobars. Strong wind blowing approximately along the isobars. Strong wind blowing perpedicularly to the isobars.

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

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

11. Which of the phenomena occurring on the II. kind cold front are particularly dangerous for low-flying aircraft?

High pressure and temperature drop. Strong turbulence limited to the narrow space of vortex - the microburst, with axis approximately at the base of Cb - cumulonimbus cloud. Drop of cloud base, sometimes even to the ground.

12. The change of physical state ice - water vapor is called:

evaporation sublimation condensation

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

16. When entering a downdraft:

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

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 heading of aircraft and its direction of movement compare to ground is:

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

19. What does the term „spin” mean?

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

20. 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. Positions of gliders on the ground which landed earlier. Circling of birds of prey, direction of cloud shades movement and waves on water surfaces.

21. 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 collapsed side and light break of the non collapsed side to keep the glider in straight flight. weight shift into the non collapsed side and light break of the same side to keep the glider in straight flight.

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

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

23. The most suitable maps for aeronautical navigation are:

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

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

25. Magnetic course is measured:

from geographical north of local meridian. from bearing indicator. from prime meridian.

26. Course is measured in degrees from north:

clockwise to the east and counterclockwise to the west. clockwise. counterclockwise.

27. Geographical North and South:

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

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

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. turning only in the side where the steering line is OK.

29. In strong wind a pilot flew in a place where his ground speed against the wind is zero:

He should keep flying against the wind and emergency-land in the terrain below him. He should fly with sidewind or windwards as the terrain allows as far as possible to an alternative landing field. He should step in the speed bar and make big ears.

30. For emergency landing You would prefer:

trees. water. buildings.

31. 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.

32. If a pilot is being dragged by strong wind along the ground, he should:

pull the steering lines or rear lines/risers. wait until the glider stops itself. pull the A risers or lines.

33. The reserve parachute is used so that:

By pulling the handle the reserve parachute is activated; the handle can be lost. Pull the rezerve parachute handle; when the needles are torn out, the reserve parachute opening system is activated. Pull the reserve parachute from the harness and throw it into a free space letting go the handle too.

34. Restricted air space (LK R):

must be passed through. must not be passed through. can be passed through under specified conditions.

35. Flying a paraglider is allowed:

only during a day, which means between morning civil twilight and evening civil twilight or in a similar period of time which can be designated by a competent authority. in VFR conditions during a day; a day is considered as a time period between sunrise and sunset. from sunset to sunrise.

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 except for ridge soaring. 150 m

37. From a sport aircraft (SLZ) it is forbidden:

to spray. to drop things between sunrise and sunset. to drop anything or spray, except under certain conditions.

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

The course must be kept but speed can be changed. These conditions must not be changed. This rule does not relieve the aircraft commander of responsibility to carry out such measures that will the best prevent a collision.

39. 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:

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

40. Airport operations are:

all vehicles and persons operations on the aerodrome area. 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.

41. A paraglider is the most damaged by:

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

put the afflicted in a semi sitting position, pull out the sherd and apply compressing bandage. 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. 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.

44. An afflicted suddenly collapsed during the ascent of the hill, he is lying down not moving, takes a deep breath about once in twenty seconds. Another witness of the incident tries to feel pulse on his neck and reports weak and rapid pulse. It is necessary to call for help immediately and:

Turn the afflicted into a stabilized position because there is a risk of vomit aspiration. Initiate resuscitation. So called "gasping breaths" are typical of sudden cardiac arrest. Pulse palpation by layman is unreliable and is not used for large number of errors - the first aider can feel his own heartbeat. Initiate artificial respiration because this breathing frequency is too low. Indirect heart massage is not needed because there are heartbeats and massage might damage lungs.

45. „Surgical” rubber gloves:

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

46. If improvised transport of an insured PG pilot is necessary (for example in difficult terrain), as the best means of transport will serve:

his paragliding harness. the canopy folded in a suitable rectangular shape. into a stretcher tied straight branches.

47. A pilot should have his mobile phone:

switched off because the aviation regulations forbid the use of mobile phones in flight. placed in the pocket of the harness so that it could not cause any injury in case of an accident. placed so that it could be reached in any position of pilot’s body.

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

112 155 1210

49. 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 stand with one arm up and second arm along the body (a paraphrase of the letter N). to wave by any object of red color.

50. Resuscitation (animation) is needed to be performed if the afflicted:

is unresponsive, not moving, regardless of the state of breathing (a layperson is not able to reliably judge the respiratory status). is unresponsive, not moving and not breathing, or only "gasping" breaths are seen. is unresponsive and there is no pulse on carotid artery (the breathing state is not important).
