Test - PL A

1. Turning of a paraglider is the result of:

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

2. The lift on the aerofoil is created by:

densification of streamlines below the aerofoil, the lower surface of the aerofoil thus generates a negative pressure; above the aerofoil the streamlines expand and thereby an overpressure occurs above the aerofoil. the force of flowing air from front of the aerofoil (when the angel of attack is positive). densification of streamlines above the aerofoil, the top surface of the aerofoil thus generates a negative pressure; below the aerofoil the streamlines expand and thereby an overpressure occurs beneath the aerofoil.

3. The wing aspect ratio:

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

4. The lift coefficient is influenced the most by:

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

5. Larger part of lift is generated:

below the aerofoil, around 2/3. above 2/3 of the aerofoil, around 55%. above the aerofoil, around 2/3.

6. Induced drag:

arises as a result of interference between flows around different parts of an aircraft. 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.

7. When the surface load changes the glide ratio:

changes because effective bearing area is the same. changes because the relation between lift and drag does not change. does not change because the relation between lift coefficient and drag coefficient does not change.

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

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

9. Condensed isobars on the synoptic map indicate:

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

10. Dangerous storm phenomena are:

strong updrafts and hight of the Cb could. 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.

in winter at midday. in summer at midday. at noon.

12. At the passing active II. kind cold front we encounter typical dangerous phenomena:

strong turbulence, severe icing, active thunderstorm activity, heavy showers, strong winds. low clouds, thick stratiform clouds and strong persistent rainfall. icing, persistent rainfall, impaired visibility.

13. Which of these cloud species belong among clouds of crystal composition?

Ns - nimbostratus, As - altostratus Cc - cirocumulus, Cs - cirostratus Cb - cumulonimbus, Ac - altocumulus

14. On the northern hemisphere, the height of the troposphere, depending on latitude:

decreases from south to north. increases from south to north. is the same during the whole year.

15. The 10 m/s wind speed is:

33,3 km/h. 30 km/h. 36 km/h.

16. 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 just above its lee side turning 180° into the wind at the turn points which means against the slope. we fly alongside a slope at its windward side turning 180° into the wind at the turn points.

17. 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.

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

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

19. What does the term „spin” mean?

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

20. 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.

21. I increase the flight speed by:

depressing the speed system. pulling a bit of steering. pulling the trimmers.

22. Geographic coordinates indicate:

certain geographical location. certain place name. time zone position.

23. The prime meridian is:

meridian, also called the base meridian, passing through Greenwich Observatory in England. the meridian, at which the latitude and longitude equal 0. a meridian not passing through observatory in Greenwich, but only a small circle.

24. 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.

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

Paris. Moscow. London.

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

There is no difference. 2 hours. 1 hour.

27. Magnetic course is measured:

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

28. In strong wind a pilot flew in a place where his ground speed against the wind is zero:

He should keep flying against the wind and emergency-land in the terrain below him. He should fly with sidewind or windwards as the terrain allows as far as possible to an alternative landing field. He should step in the speed bar and make big ears.

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

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

30. When flying on speed system:

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. The paraglider is prone to symmetrical or asymmetrical collapses.

31. For emergency landing You would prefer:

water. trees. buildings.

32. A glider with an asymmetric collapse tends to:

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

33. 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 use a reserve parachute which is more stable in turbulences. to do big ears which will help to fly through turbulences by increasing surface load of the wing.

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

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

35. Airdrome traffic zone - ATZ is:

a segregated airspace with a permanent information service. a segregated airspace, which serves to protect airport operations. a segregated airspace with air traffic control service.

36. What is it CTR?

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

37. The aircraft, that is obliged by the rules to give way to another aircraft, must:

avoided so that the maintained vertical distance between aircrafts was 150 m. avoid by flying above or under or cross the other aircraft flight line at a sufficient distance. avoided so that the maintained horizontal distance between aircrafts was 300 m.

38. The prohibited airspace (LKP):

outside the clouds with permanent ground visibility. at a distance to the clouds more than 5 km horizontally and 300 m vertically. at a distance to the clouds more than 1,5 km horizontally and 150 m vertically.

41. 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.

42. Risers are:

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

43. A layperson without special training is performing resuscitation:

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

44. Fractures of upper limbs are preferably fixed by:

using an improvised splint (branch, stick, etc.). hanging in a triangular bandage. tightening to the body in extended position.

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

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

46. During an unsuccessful landing a pilot flew through a window and cut his wrist so badly that the wound is heavily bleeding, blood squirts. 10 cm long piece of broken glass projects from the wound. The afflicted person is conscious, pale, complaining of pain in his right ankle which is evidently deformed. We'll call an ambulance and:

fix the leg, lay the afflicted in the anti shock position, lift the wounded hand up and if the bleeding doesn’t stop, apply a compressing bandage. lay the afflicted down on his back with legs lifted, apply a tourniquet on his forearm tightening it gently. We do not pull out the piece of glass on principle. put the afflicted in a semi sitting position, pull out the sherd and apply compressing bandage.

47. The most essential first aid actions that can be performed in the event of serious accident are:

fixing the bone fractures, treatment of wounds and abrasions. gentle transportation to the place of professional help. to stop heavy bleeding, clearing the airway and fight against heat loss.

48. During ridge soaring after a collapse about 10 meters above ground a pilot landed hard on his left side; He is obviously shaken, however gets up, then collapses, is pale, reports pain in his hip, shakes, he wants to sleep, a little confused, but strictly refuses an offered call for an ambulance. The procedure will be:

We are trying to calm him down, keep him in a position which is the most comfortable for him, cover him and call the emergency services. We lay him in the anti-shock position with his feet up, cover him and call an ambulance. We lay him in shade into semi sitting position and check him occasionally during flying. If his condition gets worse, we call help.

49. 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 with one arm up and second arm along the body (a paraphrase of the letter N). to stand and rhythmically move arms up and down wit palms turned upwards.

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

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