1. The paraglider glide ratio is defined as:

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

2. The polar line is a chart expressing:

the speed and drag ratio. the vertical speed and horizontal speed ratio. the horizontal speed and angle of attack ratio.

3. 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.

4. Surface load:

indicates the number of kilograms of the total weight per m2 of bearing area. indicates the number of m2 of bearing area per one kilogram of the total weight. indicates the number of kilograms of the pilot weight per m2 of bearing area.

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

the drag and the gravity force. the weight of the aircraft and lift. the gravity force and resultant aerodynamic force.

6. On the bottom side of the wing in flight there is:

overpressure. no pressure. negative pressure.

7. The lift coefficient is influenced the most by:

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

8. Turning of a paraglider is the result of:

changes in the distribution of aerodynamic forces on the canopy. changes of the size of projected area of the canopy. changes in the distribution of aerodynamic forces on one half of the canopy.

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

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

10. In which of the following changes of state is latent heat released?

Gas into liquid. Solid substance into gas. Liquid into gas.

11. Condensed isobars on the synoptic map indicate:

pressure level of the area. high temperature difference. greater pressure difference and therefore stronger wind.

12. What temperature stratification is favorable for the occurence of vertical motions in the troposphere?

stable instable indifferent

13. Which of the phenomena occurring on the II. kind cold front are particularly dangerous for low-flying aircraft?

High pressure and temperature drop. Strong turbulence limited to the narrow space of vortex - the microburst, with axis approximately at the base of Cb - cumulonimbus cloud. Drop of cloud base, sometimes even to the ground.

14. Vertical robustness of the troposphere is the greatest:

in the temperate zones. over the poles. over the equatorial regions.

15. Stationary front is the one that:

is moving in leaps. is not moving or moves very slowly. is moving only clockwise.

16. The take off control includes:

the check of harness, lines, canopy, weather and space. the check of glider and harness wear and tear, stitching, carabiners, helmet and instruments. the check of canopy, carabiners, weather and space in the direction of flight and landing.

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

Three. Five. Seven.

18. When entering a thermal current:

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. the canopy always tends to collapse and therefore the pilot must brake.

19. So called escaping maneuvers include:

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

20. When entering a downdraft:

the canopy tilts backwards and can shoot forward afterwards. the canopy shoots forward and there is a danger of frontal collapse. the canopy tilts sidewards and can get asymmetric collapse.

21. 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. the same when flying in no wind or exactly against the wind or with the wind. always the same.

22. When performing comparative orientation it is always more reliable:

to carefully view the terrain below the aircraft. to focus on one landmark. to locate and identify several landmarks.

23. Sooner then in Prague, the sun rises in:

Moscow. Paris. London.

24. The horizontal velocity is given:

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

25. Magnetic course is measured:

from prime meridian. from geographical north of local meridian. from bearing indicator.

26. 225 degrees is direction:

south east. south west. north west.

27. Magnetic north is a direction given by:

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

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

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

29. After an asymmetric collapse the correct procedure is:

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 pulling the steering on the not collapsed side quickly and fully to help the regeneration of the canopy.

30. After a tall tree landing:

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

31. If the steering line brakes, the correct procedure is:

turning only in the side where the steering line is OK. steering via weight shift and cautious pulling of the rear risers. steering by another suitable line and the other steering line or, if there is enough hight, use the reserve parachute.

32. You miscounted the landing approach and need to shorten it. You are 30 m above the ground:

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. 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.

33. Your special equipment for safety maneuvers training should be:

a life jacket, an orange helmet and light shoes. a life jacket and a flare. a life jacket, a hook knife for cutting lines or risers.

36 months for persons between 30 and 60 years of age. 12 months for persons above 60 years of age. 24 months for persons between 35 and 60 years of age.

37. Pilots must have the documents required for flying a light aircraft:

with them at flights outside the airport. with them at every flight. with them at cross country flights.

42. A paraglider is the most damaged by:

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

43. „Surgical” rubber gloves:

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

44. After applying tourniquet the wound is still bleeding:

We need to use another compress bandage. The tourniquet needs tightening. Loosen the tourniquet and lift the afflicted limb up.

45. Fractures of lower limbs are preferably fixed by:

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

46. In improvised conditions fracture fixing is:

needed in exceptional cases if manipulation with the patient before professional medical services arrival is necessary. a priority first aid objective. necessary in case of open fracture.

47. 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:

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

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

158 155 150

49. Choose the true statement about using the thermal („space”) blanket:

The foil is a very good thermal isolation but does not protect against moisture - it can leak in strong rain. The side doesn’t matter, the important is to wrap it tightly all around the patient. This blanket can be also used as a tourniquet or improvised bandage.

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

an inspection of afflicted "head to toe" in order to uncover any injury changes on body. 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.
