2. In a normal steady flight:

there is overpressure on the upper and lower surface of the wing. there is negative pressure on the upper surface and overpressure on the lower surface of the wing. there is overpressure on the upper surface and negative pressure on the lower surface of the wing.

3. The wing aspect ratio:

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

4. The glide ratio relative to ground:

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

5. 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.

6. The aircraft falls when:

the pilot makes too sharp turn. the aircraft take off weight is higher then maximum allowed. it gets over the critical angle of attack.

7. The separation of streamlines is when:

the airflow becomes detached from the surface of the aerofoil. turbulent flow around the upper surface of the wing switches to laminar flow. the streamlines leave the aerofoil after copying its shape.

8. Bringing a paraglider close to the critical angle of attack is manifested by:

decrease of steering forces. sudden increase of descent rate. significant rise of forces in steering lines.

9. What vertical temperature stratification is typical for advection fog?

Isothermy. Inversion. Drop of temperature with altitude.

10. Lentil shaped elongated clouds:

occur mainly in the tropics; in our latitudes they appear rarely in the spring at the sudden change in temperature. especially in summer indicate coming of a dangerous occluded front. indicate strong wind at hight and wind gusts danger.

11. The change of physical state water - water vapor is called:

evaporation sublimation condensation

12. Dangerous storm phenomena are:

the density of the Cb cloud which consists of liquid and solid state of water. strong updrafts with maximums in the upper half of CB cloud, stong turbulence, strong downdrafts with maximums near the CB cloudbase, frosts, electric characteristics of the Cb cloud. strong updrafts and hight of the Cb could.

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

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

14. In our latitudes a vertically developed Cb cloud can reaches the height of:

4 km 1 km up to 15 km, or rarely even more.

15. How the air masses move in a warm front?

Warm air shifts above the cold air mass. Warm air shifts below the cold air mass. Cold air shifts above the warm air mass.

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. The heading of aircraft and its direction of movement compare to ground is:

the same when flying in no wind or exactly against the wind or with the wind. always the same. the same when flying in no wind or with the wind exactly from left or right.

18. 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. down at a sufficient distance from the mountain top. at the top of the mountain.

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

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

20. So called escaping maneuvers include:

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

21. When entering a thermal current:

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

22. 225 degrees is direction:

south east. north west. south west.

23. Comparative navigation involves:

comparing terrain with a map and vice versa. comparing the calculated times with the reality. comparison of data of navigation devices (GPS) with a map.

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

Paris. London. Moscow.

25. 10 cm in map with 1 : 200 000 scale refers of real distance:

200 km 20 km 50 km

26. The difference between UTC and Central European Summer Time (CEST) time is:

There is no difference. 2 hours. 1 hour.

27. The most suitable maps for aeronautical navigation are:

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

28. If during a flight the reserve parachute drops out accidentally and opens:

I prepare for the landing on the rescue, nothing else can be done anyway. I should try to collapse the glider canopy by pulling rear risers or steering to minimise its influence into reserve parachute flight and I should get prepared for landing. I should collapse the rescue parachute by pulling its lines.

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. For emergency landing a pilot would rather choose:

dense forest. a forest road. a lonely tree.

31. A glider with an asymmetric collapse tends to:

fall quickly and therefore it is necessary to prevent such situations at any cost. turn rapidly to the side with the collapse and then rotate or slowly return into straight flight. fly on, but pilots tend to do unwise piloting inputs.

32. Use the reserve parachute without hesitating:

after being blown behind a mountain ridge. in rapid uncontrolable rotation. under a Cumulonimbus cloud.

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

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

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. Restricted air space (LK R):

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

36. The AGL abbreviation by a height data in the airspace map means:

the hight according the local atmospheric pressure. the hight above the ground level. the hight above the see level.

37. Can I meet an airliner in Class E airspace?

Yes. No. Only in clouds.

38. Czech abbrevation SLZ means:

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

39. 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:

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

40. The lower limit of a control zone (CTR) is formed by:

the ground surface. the upper limit of the G class air space. a specified altitude.

41. 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.

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. The helmet of the afflicted:

must never be taken off. should be taken off only by gente tilting nad twisting. should be taken off by pulling in the long axis of the body with permanent fixation of the head and neck.

44. 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.

45. 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.

46. A layperson without special training is performing resuscitation:

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

47. 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.

48. A foreign object (e.g. little stone, sherd or so):

must be removed even if surrounding tissue is damaged and then the wound needs rinsing with disinfection. is to be removed from a wound if it is possible without excessive violence (e.g. rinsing with water, gently pulling etc.). is never to be removed - cover the wound with anything in it and soak the bandage with disinfection.

49. Choose the true statement about tactics when you are a witness of a severe injury:

If we witness an accident, we call emergency service after a thorough examination, to make sure that the situation is really serious. Before calling an emergency service it is appropriate to make at least indicative examination where the accident happened, what happened and how many affected there are. First, you need to restore vital functions as quickly as possible, and only then deal with calling for help.

50. If the arrival of a rescue helicopter is expected, rescuers on the ground should stand so that:

they were evenly distributed around the expected landing site and they could prevent potential arrival of other persons. they were in the best possible place for a landing; just before touchdown they move in front of the helicopter. they were always in the visual field of the helicopter pilot.
