Test - PL A

1. The paraglider glide ratio is defined as:

the ratio between the horizontal and vertical velocity component of the paraglider. the weight and lift ratio. the relation between the glider performance and vertical speed.

2. Lift is:

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

3. When an aircraft is flying with such an angle of attack that its gliding ratio is ', it means that:

it will fly 1 km in 10 s. it is flying under an angle 10° towards the ground. it will fly 10 km far from altitude 1 km in no wind.

4. 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.

5. 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 drag coefficient drops abruptly. the lift coefficient sharply increases.

6. Can we read the best glide ratio speed in front wind from the polar line?

Yes. Only for tail wind. No.

7. 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.

8. The lift acts:

always upwards from the aerofoil. always perpendicularly to the chord. always perpendicularly to the direction of flow attacking the aerofoil.

9. Coriolis force acting on the wind is:

inertia force causing bodies movement deflection, thus also the air flow. the centrifugal force. the friction force.

10. Among high level clouds are:

St – stratus, Sc – stratocumulus Cc – cirrocumulus, Cs – cirrostratus Cu – cumulus, Ac – altocumulus

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

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

12. Low level cloud can be:

St – stratus Ac – altocumulus Ci – cirrus

13. 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:

cyclone filling. cyclone extinction. oclusion.

14. Half of the weight of the earth's atmosphere is located in the bottom:

8 km 3 km 5 km

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

crystallization solidification condensation

16. So called escaping maneuvers include:

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

17. 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. at the top of the mountain. down at a sufficient distance from the mountain top.

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

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

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

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

20. The take off direction and place choice is subject to:

the wind in the valley by the landing zone. the wind at the take off considering the wind direction above the mountain ridge. the wind reported by the nearest meteorological station.

21. When entering a thermal current:

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

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

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

23. Geographic coordinates indicate:

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

24. 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 magnetic poles. the marine poles. the geological poles.

25. Magnetic north is a direction given by:

the compass needle free of any interferences. measurements on a map. the theoretical line intersecting the earth center and the surface of the earth in points called magnetic north and magnetic south.

26. The prime meridian is:

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

27. The horizontal velocity is given:

in feet. in knots. in km/h, MPH or knots (kts).

28. After a tall tree landing:

you should climb down as fast as possible to show that you are OK. you should wait until your friends come and then you climb down while they are ready to catch you if needed. you should do maximum via reachable means to get professional rescue help (a cellphone or radio call, waiting for friends, whistle ect.)

29. 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. no sudden piloting inputs; a certified paraglider will return into straight flight itself. 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. The best when blown behind a ridge is: Při přefouknutí přes kopec je nejbezpečnější

to use a reserve parachute which is more stable in turbulences. 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.

31. Use the reserve parachute without hesitating:

after being blown behind a mountain ridge. under a Cumulonimbus cloud. in rapid uncontrolable rotation.

32. A glider with an asymmetric collapse tends to:

fly on, but pilots tend to do unwise piloting inputs. turn rapidly to the side with the collapse and then rotate or slowly return into straight flight. fall quickly and therefore it is necessary to prevent such situations at any cost.

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

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

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

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

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

42. Risers are:

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

43. Choose the true statement about improvised transport:

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. The priority of an improvised transport is speed.

44. To prevent heat loss the most effective is:

To cover dressed afflicted gently with an "anti-shock" foil. To wrap dressed afflicted tightly in an "anti-shock" foil. To wrap undressed afflicted tightly in an "anti-shock" foil.

45. Resuscitation without artificial respiration is performed:

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 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 continuous chest compression at rate of about 100 times per minute.

46. The most effective anti shock precautions in laic first aid (after securing vital functions) are:

thermal comfort, lots of sweet liquids, position on side. fracture fixing, wound and abrasions treatment. convenient position, thermal comfort, calming.

47. The helmet of the afflicted:

should be taken off only by gente tilting nad twisting. 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.

48. "Secondary examination" of an injury afflicted means:

an examination by another independent person to verify the initial conclusions. the second (and next) control examination to determine if there is a deterioration in the status. an inspection of afflicted "head to toe" in order to uncover any injury changes on body.

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

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

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.
