Test - PL A

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

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

2. Induced drag:

arises as a result of parasitic energy induced by air rfiction around an aircraft. arises as a result of air flow from the lower wing surface, around the wingtip, towards the upper wing surface due to a pressure difference. arises as a result of interference between flows around different parts of an aircraft.

3. 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.

4. Glide ratio is influenced only by:

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

5. At minimum speed:

the paraglider or powered paraglider will fly the farthest. the paraglider or powered paraglider is close to stall. the paraglider or powered paraglider will fly the longest.

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

stays the same. increases. decreases.

7. The inner wing side angle of attack of a turning paraglider:

is changing because the wing banks in the same moment. is not changing. is changing due to a change of trailing edge position.

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

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

9. What are the other two conditions, besides forces causing air lift, necessary for the creation of a thunderstorm?

Unstable conditions and high air humidity. Unstable conditions and low air pressure. Stable conditions and high air pressure.

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

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

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

crystallization condensation solidification

12. If a paraglider or powered paraglider pilot sees a Cumulonimbus cloud while flying, he should:

land on a suitable landing field as soon as possible. fly under the cloud in a safe vertical distance from its cloud base. fly around the storm area in a safe distance.

13. With increasing altitude the wind speed usually:

increases. decreases. increases in the summer and decreases in the winter.

14. Characteristic typical for the troposphere is:

temperature drop with hight. isothermal stratification. rise of pressure with hight.

15. Cooling speed of rising air saturated with water vapor is less than of unsaturated air because:

condensation releases heat. water vapor absorbs heat radiated by air. water vapor is not cooled as fast as dry air.

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

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

17. The take off direction and place choice is subject to:

the wind at the take off considering the wind direction above the mountain ridge. the wind reported by the nearest meteorological station. the wind in the valley by the landing zone.

18. 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.

19. When entering a thermal current:

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

20. B-stall is performed by:

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

21. So called escaping maneuvers include:

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

22. Magnetic course is measured:

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

23. Terrain formations such as forests, meadows, lakes, castles, roads, railways etc. are called:

map projections. topographic situation. topographic area.

24. The location of geographical and magnetic poles is:

not identical. identical. The magnetic pole is always to the east from the geographical pole.

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

1 hour. 2 hours. There is no difference.

26. Contour lines are curves connecting points of the same:

declination. negative hight, so called dephtines. alitude.

27. Time of sunrise and sunset varies:

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

28. When sucked in a vertically developed cloud the best to do is:

to steer the glider straight into the lightest part of the cloud. to keep circling through the cloud as high as possible and so fly over it. to perform the most effective escape maneuver and try to keep flying against the wind.

29. 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.

30. For emergency landing You would prefer:

buildings. water. trees.

31. The best when blown behind a ridge is: Při přefouknutí přes kopec je nejbezpečnější

to fly with the wind as far as possible to a possible emergency landing field. to do big ears which will help to fly through turbulences by increasing surface load of the wing. to use a reserve parachute which is more stable in turbulences.

32. A glider with an asymmetric collapse tends to:

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

33. After an asymmetric collapse the correct procedure is:

pulling the steering on the not collapsed side quickly and fully to help the regeneration of the canopy. 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 no sudden piloting inputs; a certified paraglider will return into straight flight itself.

34. Restricted air space (LK R):

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

35. Czech abbrevation SLZ means:

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

36. 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:

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

37. Except for takeoff or landing or except by permission issued by the Authority a VFR flight must be conducted above the ground or water at a height of not less than:

150 m 300 m 150 m except for ridge soaring.

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

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

39. In G class airspace there is:

a request of permanent two way connection. a request of connection for flights above 150 m AGL. no request of connection.

40. A proof of liability insurance must be on board during all flights.

Not during an airport flight. Yes. No.

41. Risers are:

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

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

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

44. To prevent heat loss the most effective is:

To wrap dressed afflicted tightly in an "anti-shock" foil. To cover dressed afflicted gently with an "anti-shock" foil. To wrap undressed afflicted tightly in an "anti-shock" foil.

45. Improvised tourniquet is to be applied:

anywhere between the wound and heart. only at arm or thigh, between a wound and heart. always about 10 - 15 cm above the wound.

46. The best way of use of the „anti-shock” foil (thermal blanket) is:

It is laid under the afflicted. The afflicted is carefully covered with it. The afflicted is tightly wraped into it including head, only face is uncovered.

47. Choose the true statement about improvised transport:

The most important is that the afflicted stays in a slightly inclined position with head down during the whole transport. The priority of an improvised transport is speed. Unless it is necessary the patient should not be transported before the arrival of professional assistance.

48. Resuscitation (animation) is needed to be performed if the afflicted:

is unresponsive, not moving and not breathing, or only "gasping" breaths are seen. is unresponsive, not moving, regardless of the state of breathing (a layperson is not able to reliably judge the respiratory status). is unresponsive and there is no pulse on carotid artery (the breathing state is not important).

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

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