Test - PL A

1. Lift arises when an aerofoil is in flow due to the creation of a pressure differential above and below the aerofoil. What is the pressure below and above the aerofoil and what is the ratio of their sizes at normal angles of attack?

There is overpressure below the aerofoil and negative pressure above the aerofoil in the ratio of 1/3 of overpressure and 2/3 of negative pressure. There is overpressure below the aerofoil and negative pressure above the aerofoil in the ratio of 1/3 of overpressure and 2/3 of negative pressure.

2. What will be the change of flow speed and static air pressure in a place where the streamline density increases?

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

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

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

4. The total weight of a pilot with all equipment is 100 kg and the area of the glider is 25 m2. The surface load of the paraglider is:

0.25 kg/m3 0.4 kg/m3 4 kg/m3

5. Glide ratio is influenced only by:

total weight. the angle of attack (i.e. lift and drag coefficients). the velocity of flow.

6. The aerodynamic drag is a sum of:

parasitic drag and supportive drag. form drag, friction drag, induced drag and interference drag. parasitic drag, form drag, interference drag and rolling drag.

7. How the speed system works?

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

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

increases. stays the same. decreases.

9. The form of precipitation falling out of vertically developed cloud type Cb - cumulonimbus is mostly:

rain and hail. drizzle. light rain.

strait into the middle of the low pressure in the whole area. clockwise. counter clockwise.

11. Humidity means:

the amount of water vapor in the air precipitation fall snowing

12. The low pressure system - Cyclone - is the area:

of low atmospheric pressure with the minimum value in its middle. of low atmospheric pressure with the minimum value on its bordes. where the atmospheric pressure is decreasing outwards.

15. The land breeze:

blows at night and is weaker than the see breeze. blows during a day and is stronger than the see breeze. blows during a day and is weaker than the see breeze.

16. What does the term „spin” mean?

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

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

at the top of the mountain. 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.

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

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

19. When entering a thermal current:

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. the glider usually tends to collapse and therefore the pilot should break a bit before turning.

20. So called escaping maneuvers include:

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

21. When entering a thermal current:

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

22. Which of the following conditions is the most important for comparative navigation?

Navigational preparation before flight, map, visibility of ground. Experience of the pilot and his estimation. A good map and navigation skills of the pilot.

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

27. The horizontal velocity is given:

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

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

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

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

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

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

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

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

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

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

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

33. If one side of canopy is stalled, the pilot should:

pull the second steering fully and then release both. hold down the already pulled steering and counter-steer the rotation by weight-shift. release the steering continuously.

34. Conducting a paragliding training is only allowed to:

a competition pilot, a PG instructor and a PG instructor in training. a PG instructor and a PG instructor in training. a sport pilot and a PG instructor.

35. LAA regulation, which governs the rules of flying a paraglider in the Czech Republic is called:

ZL - 3 PL - 2 ZL - 1

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

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. the ability to see forward from the cockpit of the aircraft in flight determined by meteorological conditions and expressed in units of distance.

39. The aircraft, that is obliged by the rules to give way to another aircraft, must:

avoided so that the maintained vertical distance between aircrafts was 150 m. avoided so that the maintained horizontal distance between aircrafts was 300 m. avoid by flying above or under or cross the other aircraft flight line at a sufficient distance.

40. 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.

41. Initial examination includes:

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. fast check of the afflicted „from head to toe” with emphasis on injury signs.

42. A paraglider is the most damaged by:

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

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

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

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

45. A layperson without special training is performing resuscitation:

by chest compressions only. by chest compressions and artificial respiration in ratio 30:2. by chest compressions and artificial respiration in ratio 15:2.

46. If it is obvious that the action of rescue helicopter is necessary, in the Czech Republic it is preferably needed to call number:

112 1210 155

47. 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 the anti-shock position with his feet up, cover him and call an ambulance. 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 shade into semi sitting position and check him occasionally during flying. If his condition gets worse, we call help.

48. If one layer of pressure bandage is not enough to stop bleeding from a wound on leg:

We apply another 1 or 2 layers or, if still not enough, use a tourniquet. We urge the arrival of emergency services and re-emphasize the urgency of the case. We take off the old bandage and apply a new one and tighten it better.

49. Signal to perform by a person on the ground to cancel the need of rescue helicopter landing is:

to stand with one arm up and second arm along the body (a paraphrase of the letter N). to stand and rhythmically move arms up and down wit palms turned upwards. to wave by any object of red color.

50. Resuscitation without artificial respiration is performed:

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