2. In the moment of flying in a sinking currant the angle of attack:

decreases. does not change. increases.

3. Glide ratio is influenced only by:

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

4. 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.

5. The glide ratio relative to ground:

is changing when flying in wind. is changing with weight changes. is not changing when flying in wind because the bearing area is still the same.

6. There are aerodynamic forces generated on a body in flow. They are called:

lift and overpressure. the resultant aerodynamic force which is sum of lift and drag. lift, mass and drag.

7. The induced drag can be reduced by:

aspect ratio and favorable wing tip shape. the wing arrow and air foil thickness. the air foil thickness and special

8. The lift on the aerofoil:

is created due to angle of attack and change of air temperature above and below of the wing. is generated by the Coriolis force and by equalizing pressure above and below the aerofoil. is created due to different speed of flow above nad below the aerofoil.

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

light rain. rain and hail. drizzle.

12. Which of the listed fog types is usually dissolved by increasing surface wind speed?

Frontal fog. Radiation fog. Advection fog.

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

Drop of cloud base, sometimes even to the ground. 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.

14. Among the typical local winds belongs the wind called "Föhn":

It blows from the mountains to the valley. It blows from the valley to the mountains. It blows especially in vast dry plains in the autumn.

15. 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.

16. An asymmetric collapse of about 1/2 of the leading edge should be solved by:

weight shift into the collapsed side and light break of the non collapsed side to keep the glider in straight flight. weight shift into the non collapsed side and light break of the same side to keep the glider in straight flight. no inputs in steering letting the glider reinflate.

17. Spiral is performed by:

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. 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.

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

Five. Three. Seven.

19. 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.

20. When entering a thermal current:

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

21. 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.

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. Contour lines are curves connecting points of the same:

negative hight, so called dephtines. alitude. declination.

24. 9 cm in map with 1 : 500 000 scale refers of real distance:

London. Paris. Moscow.

26. Direction south is reported by:

180° 360° 090°

27. The flight velocity displayed by GPS is:

true air speed. ground speed. indicated air speed.

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

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. By flying in figure eight or S turns you loose hight before the final glide.

29. A glider with an asymmetric collapse tends to:

fall quickly and therefore it is necessary to prevent such situations at any cost. 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.

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

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

31. 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.

32. After an asymmetric collapse the correct procedure is:

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. no sudden piloting inputs; a certified paraglider will return into straight flight itself.

33. If I stall the glider:

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

34. VFR flights in C, D and E classes airspace may be carried out at a distance from clouds:

at least 1500 m horizontally and 300 m vertically. only the first at the cloud base pilot can fly in into the cloud. outside the clouds and in visibility of ground.

35. What is it CTR?

Terminal controlled area. An air space where VFR flights are forbidden. Control zone of an airport.

36. To indicate the height after passing through the transition altitude the setting goes from QNH values:

to the altimeter setting at the value of 1013.2 hPa and vertical positions of the aircraft are expressed in flight levels. to the altimeter setting at QFE of the target airport and vertical positions of the aircraft are expressed in hight over the target airport. to the altimeter setting at QFE and vertical positions of the aircraft are expressed as hight above the ground.

37. TMA (Terminal Control Area)

can be flown under only with a two way radio communication with AFIS. cannot be flown under or over. can be flown under.

38. Verifying whether a paraglider technical certificate is valid is a duty of:

the operator. the aircraft commander (pilot). the head of air traffic.

39. Flying above a gathering of people at such a height that would not allow a safe landing in case of danger without endangering pilots or people on the ground is:

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

40. The minimum allowed flight visibility in class E airspace is:

5 km 8 km 1,5 km

41. Risers are:

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

42. 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.

43. The signal to the rescue helicopter from persons on the ground is done:

by standing with arms up in Y shape. by standing with arms stretched sideways in A shape. by waving any object of bright color.

44. Fractures of lower limbs are preferably fixed by:

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

45. In practice, we can recognize the malfunction of blood stream (cardiac arrest) by the fact that:

we cannot feel the heart beating on the chest. we cannot feel the pulse at the carotid artery. the afflicted is unresponsive, does not breath or does only gasping breaths and does not move.

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

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

47. 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.

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

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

49. 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.
