Test - PL A

1. The polar line is a chart expressing:

the vertical speed and horizontal speed ratio. the horizontal speed and angle of attack ratio. the speed and drag ratio.

2. A paraglider stall occures when:

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

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

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

4. At the critical angle of attack:

the lift coefficient reaches its maximum values, over further increasing of the angle of attack the lift coefficient decreases abruptly. the lift coefficient sharply increases. the drag coefficient drops abruptly.

5. 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.

6. If the angle of attack increases, the forward speed:

stays the same. increases. decreases.

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

8. Turning of a paraglider is the result of:

changes in the distribution of aerodynamic forces on the canopy. changes in the distribution of aerodynamic forces on one half of the canopy. changes of the size of projected area of the canopy.

9. A certain volume of moist but unsaturated air rises. Which of the following changes?

Mixing ratio. Relative humidity. Absolute humidity.

10. What temperature stratification is favorable for the occurence of vertical motions in the troposphere?

indifferent instable stable

11. Which of the layers of Earth's atmosphere is characterized by vertical movements?

Troposphere. Stratosphere. Tropopause.

12. 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:

oclusion. cyclone filling. cyclone extinction.

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

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

14. In practice we converse wind speed in m/s into kt by formula:

1 m/s ~ 1 kt 1 m/s ~ 3 kt 1 m/s ~ 2 kt

15. Which of the following cloud types are a sign of unstable air mass?

Cu, Cb St, Cs Sc, Ns

16. When entering a thermal current:

the glider usually tends to collapse and therefore the pilot should break a bit before turning. the canopy always tends to collapse and therefore the pilot must brake. the glider informs the pilot by its movements about the strength of the lift and usually also about which direction is better to turn.

17. When entering a downdraft:

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

18. B-stall is performed by:

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

19. Spiral is performed by:

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

20. 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.

21. Ridge soaring is practiced so that:

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 at its windward side turning 180° into the wind at the turn points. we fly alongside a slope just above its lee side turning 180° into the wind at the turn points which means against the slope.

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

50 km 200 km 20 km

23. Geographic coordinates indicate:

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

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

topographic area. map projections. topographic situation.

25. Direction south is reported by:

360° 090° 180°

26. 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.

27. The globe is:

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

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

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

29. After a tall tree landing:

you should wait until your friends come and then you climb down while they are ready to catch you if needed. 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.)

30. 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.

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

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

32. During flight a pilot should have his cellphone (if it is available):

in the back harness pocket so it could not break or harm the pilot in case of accident. in any place, because he cannot telephone during flight anyway. in a place, where he can reach it by any hand from the flying position.

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

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

34. A light aircraft can be steered by:

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. a pilot who holds a valid assessment on medical fitness or a student pilot under the conditions laid down in the training curriculum.

35. The pilot of the aircraft not equipped with a radio intending to arrive or leave an uncontrolled airport should:

coordinate in advance their arrival or departure with the airfield owner. observe, for the departure or arrival, the avoidance rules. coordinate in advance their arrival or departure with the AFIS unit or the aerodrome operator.

36. 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.

37. The pilot (aircraft commander) is in competence to:

The pilot has no right to decide on the execution of a flight. to obey an operator's decision on the execution of a flight. to decide definitively on the execution of a flight.

38. In G class airspace there is:

a request of connection for flights above 150 m AGL. no request of connection. a request of permanent two way connection.

39. Who is authorized to check a pilot's license or student document?

Paragliding operations inspector of LAA CR, person authorized of Ministry of Transport, Czech Police or local municipal authority personnel. Paragliding operations inspector of LAA CR, Czech Police, Czech CAA inspector, a person authorized by an airport or property owner. Paragliding operations inspector and Paragliding technical inspector of LAA CR, a person authorized by the Ministry of Transport or the CAA of the CR, Czech Police.

40. 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.

41. Initial examination includes:

finding the circumstances of the incident, the patient's problems and possible diseases which he is suffering. fast check of the afflicted „from head to toe” with emphasis on injury signs. vital functions check according to the chart A-B-C.

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

44. During an improvised transport of an unconscious afflicted:

special attention should be payed to caution and head fixation. the process should be as fast as possible. caution is not important because the unconscious afflicted doesn’t feel pain anyway.

45. After applying tourniquet the wound is still bleeding:

Loosen the tourniquet and lift the afflicted limb up. The tourniquet needs tightening. We need to use another compress bandage.

46. Choose the true statement about the obligation to provide first aid:

The obligation to provide first aid is only moral and it is not legally enforceable. Everyone who witnesses an accident is obliged to provide first aid, regardless of the severity of injury and danger. If there is serious injury, everybody is obliged to provide first aid; this assistance must not endanger the life or health of the firstaider.

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

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

48. The helmet of the afflicted:

must never be taken off. should be taken off by pulling in the long axis of the body with permanent fixation of the head and neck. should be taken off only by gente tilting nad twisting.

49. The first aid basics of wounds and abrasions treatment are:

Removing any foreign objects by rinsing, disinfecting the wound area and covering bandage. Desinfecting the wound (in emergency using even concentrated alcohol), removing any foreign objects, covering. Covering; in improvised conditions we never clean the wound and do not remove any foreign object from it.

50. 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.
