Test - PL A

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

decreases. increases. does not change.

2. A paraglider stall occures when:

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

3. 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.

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

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

5. Bringing a paraglider close to the critical angle of attack is manifested by:

sudden increase of descent rate. significant rise of forces in steering lines. decrease of steering forces.

6. The wing aspect ratio:

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

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. 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. the force of flowing air from front of the aerofoil (when the angel of attack is positive).

8. When increasing the angle of attack:

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

9. 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.

10. Which types of clouds are typical for a warm front cloud system:

Cu – cumulus, Ac – altocumulus, Cb – cumulonimbus Sc – stratocumulus, Ac – altocumulus, Cc – cirocumulus Ns – nimbostratus, As – altostratus, Cs – cirostratus

11. The part of cyclone between the warm and cold fronts is called:

the front line. the ridge of higher pressure. the warm sector.

15. Clouds in troposphere form from:

Oxygen. Nitrogen. water vapor.

16. 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.

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. 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 reported by the nearest meteorological station. the wind in the valley by the landing zone.

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

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

20. I increase the flight speed by:

depressing the speed system. pulling the trimmers. pulling a bit of steering.

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

so that the canopy is at the level of mountain top and the pilot a bit lower. down at a sufficient distance from the mountain top. at the top of the mountain.

22. 9 cm in map with 1 : 500 000 scale refers of real distance:

45 km 60 km 50 km

23. Comparative navigation involves:

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

24. The most suitable maps for aeronautical navigation are:

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

25. 045 degrees is direction:

south west. north west. north east.

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

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

27. The difference between UTC and Central European (CET) time is:

1 hour. There is no difference. 2 hours.

28. During ground handling training the glider lifts the pilot above the ground in a wind gust unexpectedly. The correct procedure is:

to release the steering and fly, steer and land back to the ground. to pull the steering fully. to pull and release the steering repeatedly and by such flapping go back to the ground.

29. When landing in water surface a pilot should steer the glider:

with the wind from a side. against the wind. with the wind.

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

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

31. For emergency landing You would prefer:

trees. buildings. water.

32. After a tall tree landing:

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

33. After an asymmetric collapse the correct procedure is:

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 no sudden piloting inputs; a certified paraglider will return into straight flight itself.

34. If two aircrafts are flying on lines facing each other or approximately such, each of them should give way by changing its course to the:

side which is more suitable for avoiding a crash. left. right.

35. The lower limit of a control zone (CTR) is formed by:

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. A proof of liability insurance must be on board during all flights.

Not during an airport flight. No. Yes.

39. Airport operations are:

all traffic at the aerodrome area and all aircrafts flying in the vicinity of the airport. all vehicles and persons operations on the aerodrome area. all flying aircrafts and aircrafts on the aerodrome operational area.

40. The definition of visibility is:

the ability to see forward from the cockpit of the aircraft in flight determined by meteorological conditions and expressed in units of distance. 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 and recognize outstanding unlighted objects by day and lights at night from the cockpit of the aircraft in flight.

41. Risers are:

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

42. A paraglider is the most damaged by:

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

43. Fractures of upper limbs are preferably fixed by:

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

44. 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.

45. Fractures of lower limbs are preferably fixed by:

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

46. Choose the true statement about a position of an unconscious afflicted:

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. If the afflicted is reliably breathing in the current position, we leave him in this position.

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

Covering; in improvised conditions we never clean the wound and do not remove any foreign object from it. 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.

48. Choose the true statement about a position of a serious injury afflicted:

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. 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.

49. A pilot should have his mobile phone:

placed so that it could be reached in any position of pilot’s body. 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.

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

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