Test - PL A

1. Lift is:

the resultant aerodynamic force generated by flow around a profile. a force generated by flow around a profile perpendicular to the drag force. an area resistance given by the angle of attack.

2. A paraglider stall occures when:

the speed system is pushed too fast. the glider overcomes the pilot when taking off. the pilot breaks too much.

3. The wing aspect ratio:

is a relationship between chord length and air foil thickens. is a relationship between span and air foil thickness. is a relationship between span squared and wing surface.

4. The aircraft falls when:

the aircraft take off weight is higher then maximum allowed. it gets over the critical angle of attack. the pilot makes too sharp turn.

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

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

6. 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.

7. The lift on the aerofoil is created by:

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. 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.

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

overpressure. negative pressure. no pressure.

9. A prerequisite for the condensation of the saturated water vapor in the troposphere is the presence of condensation nuclei which are:

solid particles. solid and liquid particles. liquid particles.

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

evaporation condensation sublimation

11. Precipitation zone of a warm front is:

at the front line and it is short rainfall. before the front line and it is persistent rainfall. mostly right after the front line and it is showers.

12. Which type of precipitation comes off water only containing clouds at mid-latitudes?

Drizzle. Intensive rain. Light rain with big drops.

13. Local isolated thunderstorms are mostly:

mass storms. frontal air lift (warm front). frontal air lift (cold front).

14. At the passing active II. kind cold front we encounter typical dangerous phenomena:

strong turbulence, severe icing, active thunderstorm activity, heavy showers, strong winds. icing, persistent rainfall, impaired visibility. low clouds, thick stratiform clouds and strong persistent rainfall.

15. The decrease of temperature with altitude in a standard atmosphere definition - vertical temperature gradient - has a value of:

1,0° C / 100 m. 0,6° C / 100 m. 0,65° C / 100 m.

16. So called escaping maneuvers include:

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

17. When entering a thermal current:

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

18. 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.

19. An asymmetric collapse of about 1/2 of the leading edge should be solved by:

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. no inputs in steering letting the glider reinflate.

20. 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.

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

at the top of the mountain. 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.

22. The most suitable maps for aeronautical navigation are:

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

23. The location of geographical and magnetic poles is:

identical. The magnetic pole is always to the east from the geographical pole. not identical.

24. When comparing the map with the terrain the most important is:

accurate compass. accurate watch. to carefully view the terrain ahead of the aircraft, alongside the aircraft and consistently compare the map with the terrain.

25. The globe is:

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

26. Magnetic course is measured:

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

27. Course is measured in degrees from north:

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

28. Your special equipment for safety maneuvers training should be:

a life jacket, a hook knife for cutting lines or risers. a life jacket, an orange helmet and light shoes. a life jacket and a flare.

29. After an asymmetric collapse the correct procedure is:

no sudden piloting inputs; a certified paraglider will return into straight flight itself. pulling the steering on the not collapsed side quickly and fully to help the regeneration of the canopy. weight shift in the not collapsed side of the glider and brake the same side slightly to stop rotation.maximálně se vyklonit na nezaklopenou stranu a také ji přibrzdit tak, aby nedošlo k rotaci

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

a parking. electric wires. water surface.

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

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. 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.

32. Before a landing into still water it is necessary:

to turn the glider against the wind. to jump out of the harness about 3 to 5 m above the water surface. to undo the harness buckles so it was possible to leave it at the moment of contact with water.

33. The best when blown behind a ridge is: Při přefouknutí přes kopec je nejbezpečnější

to do big ears which will help to fly through turbulences by increasing surface load of the wing. to fly with the wind as far as possible to a possible emergency landing field. to use a reserve parachute which is more stable in turbulences.

34. Can I meet an airliner in Class E airspace?

No. Yes. Only in clouds.

35. The upper limit of LKP airspace is:

in various altitudes (see AIP or valid ICAO map). in 1500 m AMSL. in FL 125.

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

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

37. The information about CTR, TMA, LKR, LKP position is in:

official CAA map. valid AIP or ICAO map. ADAC map.

38. The paraglider canopy is damaged mostly by:

UV rays, mechanical abrasion and humidity. storage in dark and dry rooms. mice and other wild rodents.

39. The dangerous airspace (LKD) is is an area where flying is:

prohibited. dangerous. restricted.

40. After landing at the airport, the altimeter set to the airport QFE indicates:

0. the airport altitude AMSL. the airport altitude in standard atmosphere.

41. 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.

42. Risers are:

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

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

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

44. A paraglider in a spin fell nearby. On our approach he lies on his back, unconscious, not breathing, bluish. No clearly visible injury is obvious. We'll call an ambulance and firstly:

lay the afflicted in the stabilized position. free the airway by backward head tilt. lay the afflicted in the anti-shock position with head underlaid.

45. The most essential first aid actions that can be performed in the event of serious accident are:

gentle transportation to the place of professional help. fixing the bone fractures, treatment of wounds and abrasions. to stop heavy bleeding, clearing the airway and fight against heat loss.

46. Fractures of upper limbs are preferably fixed by:

using an improvised splint (branch, stick, etc.). tightening to the body in extended position. hanging in a triangular bandage.

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

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

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 injury afflicted should always be placed on his back with his head tilted back. The unconscious afflicted must not be moved to eliminate the risk of further spine and spinal cord damage.

49. Treatment of wounds and fractures fixation of the afflicted by the accident is in the first aid performed:

always as a priority on any wound or fracture. only after the afflicted is out of vital functions malfunction danger. always if there are gaping (deep) wounds and/or open fractures.
