Test - PL A

1. The lift acts:

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

2. The optimal gliding ratio can be flown:

with just one angle of attack. with critical angle of attack. with two different angles of attack.

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. When air flow is laminar:

there is no relative mix of streamlines. there is a 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.

5. The angle of attack is:

the angle between the aerofoil’s chord and the oncoming flow. the angle between the oncoming flow and the horizon line. the angle between aerofoil’s chord and the horizon line.

6. In a steady gliding flight there is a balance between:

gravity force and lift plus drag. lift and drag. thrust and weight, drag and lift.

7. If the pilot weight increases, the wing glide ratio:

decreases. stays the same. increases.

8. How the speed system works?

It increases the angle of attack by pulling the front risers. It decreases the angle of attack by releasing the rear risers. It decreases the angle of attack by pulling the front risers. Sometimes it deforms the aerofoil shape.

9. We call it unstable stratification when in unsaturated air:

an unsaturated air particle as it exits from the equilibrium position continues to climb even when the external force ceases to act. an unsaturated particle stops at a level at which external force has ceased to act. an unsaturated particle, after removal of the external force, returns to its original position.

10. The most common wind direction in the valley caused by thermal effects is:

during the day towards the hill. during the night towards the hill. during the day down the hill.

11. The air mass is called unstable if there are:

convective vertical motions in it. inversions in it. stratified clouds in it.

12. How is relative humidity of air affected by changes in the quantity of water vapor contained in it?

It is affected only by temperature. It increases with increasing amounts of water vapor. It is not affected by water vapour amount changes.

13. The air density of the atmosphere with altitude:

doesn't change. increases. decreases.

14. What prevents the air flow from areas of high pressure directly into the area of low air pressure?

The Coriolis force. Friction on the earth's surface. The force caused by the pressure gradient.

15. What do we mean by the term "clear thermic"?

An ascending thermal current not topped by a cumulus cloud. Strong gusty wind in a coud free environment. Turbulence associated with a windshear.

16. What does the term „spin” mean?

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

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

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

18. 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. 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.

19. 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.

20. What are the possible wind direction indicators in a strange place where there is no wind sock?

Circling of birds of prey, direction of cloud shades movement and waves on water surfaces. Positions of gliders on the ground which landed earlier. Grass waves, smoke, tree shaking, moving dust or other light objects in the air.

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

22. Time is reported:

in degrees. in hours, minutes and seconds, so that a minute begins with 1. sec and ends with 60. sec. in hours, minutes and seconds, so that a minute begins with 31. sec of a past minute and ends with 30. sec of actual minute.

23. The flight velocity displayed by GPS is:

indicated air speed. true air speed. ground speed.

24. The most suitable maps for aeronautical navigation are:

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

25. The prime meridian is:

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

26. 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.

27. 045 degrees is direction:

south west. north east. north west.

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

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

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

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

30. 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.

31. 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

32. When flying on speed system:

The paraglider will increase its speed and will be more prone to symmetrical or asymmetrical collapses. The paraglider is prone to symmetrical or asymmetrical collapses. The paraglider will increase its speed and it will be more stabile thanks to better flow.

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

water surface. electric wires. a parking.

34. 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.

35. 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.

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

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

37. A Czech Pilot license holder can obtain a Sport Pilot license after:

nine months. six months. five months.

38. 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:

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

39. Czech abbrevation SLZ means:

Stálé Letové Zabezpečení = Permanent Flight Security Sportovní Létající Zařízení = Sport Flying Equipment Společná Letová Zóna = Common Flight Zone

40. To recalculate a figure in meters into figure in feet we use the simplified formula:

(m x 3) : 10 (m : 10) x 3 (m x 3) + 10%

41. 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.

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. Unless prevented by special circumstances, the best for the accident afflicted is:

a position on the side („stabilized” or „recovery” position). the "Anti-shock" position with legs and arms raised as high as possible„ a position that the afflicted person wants to take.

44. The A-B-C protocol in initial examination stands for:

1. open the Airway with a head tilt, 2. start the artificial respiration = Breathing, 3. start the chest Compressions. 1. check the Airway, 2. check the Breathing and 3. restore the Circulation (using Compressions). Anamnesis, Breathing,Chest injury check.

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

is unresponsive and there is no pulse on carotid artery (the breathing state is not important). 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.

46. During ridge soaring after a collapse about 10 meters above ground a pilot landed hard on his left side; He is obviously shaken, however gets up, then collapses, is pale, reports pain in his hip, shakes, he wants to sleep, a little confused, but strictly refuses an offered call for an ambulance. The procedure will be:

We lay him in shade into semi sitting position and check him occasionally during flying. If his condition gets worse, we call help. We are trying to calm him down, keep him in a position which is the most comfortable for him, cover him and call the emergency services. We lay him in the anti-shock position with his feet up, cover him and call an ambulance.

47. „Surgical” rubber gloves:

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

48. 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.

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

50. The telephone number of medical emergency service in the Czech Republic is:
