Test - PL A

1. How the speed system works?

It decreases the angle of attack by releasing the rear risers. 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.

2. 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 4 kg/m3 0.4 kg/m3

3. Lift is:

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

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

decreases. stays the same. increases.

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. 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.

7. The lift coefficient is influenced the most by:

the air foil thickness. the air foil curving. the speed of flow.

8. The wing aspect ratio:

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

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

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

10. The high pressure - anticyclone - is the area of:

high atmospheric pressure rising in particular direction. high atmospheric pressure with the highest value on its border. high atmospheric pressure with the highest value in its middle.

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

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

12. The boundary between two air masses, with the weather in one air mass significantly differing from the weather in the other air mass is called:

Air masses boundary. Weather boundary. Front.

13. The air density of the atmosphere with altitude:

doesn't change. increases. decreases.

14. Unsaturated adiabatic curve is showing the change in temperature with height of value:

0,65 °C / 100 m of hight. 0,60 °C / 100 m of hight. 1,00 °C / 100 m of hight.

15. Among free-convective low-level clouds is:

As - altostratus Cu - cumulus St - stratus

16. What does the term „spin” mean?

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

17. Spiral is performed by:

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

18. How many items is there in the pre start check?

Seven. Three. Five.

19. B-stall is performed by:

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

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. 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.

23. Time of sunrise and sunset varies:

depending on the intensity of sunlight. with annual periods. influenced by the magnetic field of the Earth.

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

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

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

There is no difference. 1 hour. 2 hours.

26. The flight velocity displayed by GPS is:

indicated air speed. true air speed. ground speed.

27. Geographical meridian is:

a half of meridian circle. a circle around the globe. a segment of a circle whose plane is perpendicular to the earth's axis.

28. If I stall the glider:

I use the reserve parachute; if there is not enough hight, I hold the steering down firmly. I release the steering continuously. I use the reserve parachute; if there is not enough hight, I release the steering quickly.

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

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

30. 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.

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

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

32. 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 turn the glider against the wind. to jump out of the harness about 3 to 5 m above the water surface.

33. When flying on speed system:

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

34. Airport operations are:

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

35. If two or more aircrafts heavier then air are approaching one airport with the intention to land and the avoidance rules do not apply, the priority of landing is as follows:

the aircraft flying higher gives way to the lower flying aircraft. the slower aircraft gives way to the faster aircraft. the aircraft flying on left gives way to the aircraft flying from right.

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

PL - 2 ZL - 1 ZL - 3

37. The prohibited airspace (LKP):

cannot be entered axcept with a special authorization of a competent authority. can be entered but cannot be left. can be entered only on the G class airspace level and at the indicated air speed lower then 460 km/h.

must not be passed through. must be passed through. can be passed through under specified conditions.

39. Two of the same category aircrafts are flying in one track against each other. Na vstřícné trati letí letadla stejné kategorie. Actions of avoidance are:

You will turn to the right, the other aircraft will turn to the left. Both aircrafts will change their curse to the left. Both aircrafts will change their curse to the right.

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

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

41. Initial examination includes:

vital functions check according to the chart A-B-C. 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.

42. A paraglider is the most damaged by:

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

43. Chest compression during resuscitation is performed:

in the middle of chest bone. next to left nipple. by the lower end of chest bone.

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

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

45. 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.

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

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

47. Clearing the airway of unconscious patient is done primarily using:

backward head tilt. forward head tilt. stabilised position.

48. 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. Anamnesis, Breathing,Chest injury check. 1. check the Airway, 2. check the Breathing and 3. restore the Circulation (using Compressions).

49. If the unconscious afflicted is not breathing:

First we try to free the airway. We promptly transport him to the professional medical service. We start the resuscitation immediately.

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