Test - PL A

1. When increasing the angle of attack:

the lift coefficient increases and drag coefficient decreases. the lift coefficient and drag coefficient decrease. the lift coefficient and drag coefficient increase.

2. 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 one half of the canopy. changes in the distribution of aerodynamic forces on the canopy.

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

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

4. The angle of attack is:

the angle between the oncoming flow and the horizon line. the angle between the aerofoil’s chord and the oncoming flow. the angle between aerofoil’s chord and the horizon line.

5. Can we read the best glide ratio speed in front wind from the polar line?

Only for tail wind. Yes. No.

6. Where on the aerofoil the flow separation starts?

In the wake on the suction side of the aerofoil from the leading edge end. In the boundary layer at the suction side of the aerofoil from the leading edge end. In the boundary layer at the suction side of the aerofoil from the trailing edge end.

7. Lift is:

a force generated by flow around a profile perpendicular to the drag force. an area resistance given by the angle of attack. the resultant aerodynamic force generated by flow around a profile.

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

9. Hazardous phenomena associated with a I. kind cold front are usually:

strong gusty surface wind. Cb - cumulonimbus clouds at the head of the front hidden in low stratiform clouds, turbulence and icing. Only low level clouds of stratiform types.

10. We call it unstable stratification when in unsaturated air:

an unsaturated particle stops at a level at which external force has ceased to act. an unsaturated air particle as it exits from the equilibrium position continues to climb even when the external force ceases to act. an unsaturated particle, after removal of the external force, returns to its original position.

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

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

12. A passing cold front with active storm manifestations is reflected by:

a temperature decrease later followed by its increase, no change in athmospheric pressure, wind fading. no change in temperature, slight pressure decrease and slight wind speed decrease without gusts. temperature decrease, strong athmopheric pressure decrease followed by its increase, strong wind speed increase with gusts.

13. Stationary front is the one that:

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

14. The lowest layer of the atmosphere is called:

stratosphere. troposphere. mesosphere.

15. In the northern hemisphere by proceeding vertically from the ground, the wind direction is somewhat different from the direction measured at the ground and it turns:

left. It doesn’t turn. right.

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

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

17. 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.

18. The take off control includes:

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

19. 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.

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

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

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

22. When comparing the map with the terrain the most important is:

to carefully view the terrain ahead of the aircraft, alongside the aircraft and consistently compare the map with the terrain. accurate compass. accurate watch.

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

alitude. negative hight, so called dephtines. declination.

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

Moscow. London. Paris.

a half of meridian circle. a segment of a circle whose plane is perpendicular to the earth's axis. a circle around the globe.

26. Magnetic north is a direction given by:

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. the compass needle free of any interferences.

27. 10 cm in map with 1 : 200 000 scale refers of real distance:

50 km 200 km 20 km

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

He should step in the speed bar and make big ears. 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.

29. During flight a pilot should have his cellphone (if it is available):

in the back harness pocket so it could not break or harm the pilot in case of accident. in any place, because he cannot telephone during flight anyway. in a place, where he can reach it by any hand from the flying position.

30. If one side of canopy is stalled, the pilot should:

pull the second steering fully and then release both. hold down the already pulled steering and counter-steer the rotation by weight-shift. release the steering continuously.

31. During ground handling training the glider lifts the pilot above the ground in a wind gust unexpectedly. The correct procedure is:

to release the steering and fly, steer and land back to the ground. to pull and release the steering repeatedly and by such flapping go back to the ground. to pull the steering fully.

32. For emergency landing a pilot would rather choose:

a forest road. dense forest. a lonely tree.

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

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

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

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

35. TMA (Terminal Control Area)

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

36. If two or more aircrafts heavier then air are approaching one airport with the intention to land and the avoidance rules do not apply, the priority of landing is as follows:

the aircraft flying on left gives way to the aircraft flying from right. the slower aircraft gives way to the faster aircraft. the aircraft flying higher gives way to the lower flying aircraft.

37. A pilot must have a valid pilot's license on him:

at every flight. at a flight outside the airport. at every cross country flight.

38. Airdrome traffic zone (ATZ) is of such dimensions:

a circle with a diameter of 5.5 NM (10 km), vertically from the ground to an altitude of 4000 feet (1200 meters). a circle with a radius of 3 NM (5.5 km), vertically from the ground to an altitude of 4000 feet (1200 meters). a circle with a diameter of 3 NM (5.5 km), vertically from the ground to an altitude of 4000 feet (1200 meters).

39. Czech abbrevation SLZ means:

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

40. 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.

41. Risers are:

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

42. A paraglider is the most damaged by:

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

43. The first aid basics of wounds and abrasions treatment are:

Desinfecting the wound (in emergency using even concentrated alcohol), removing any foreign objects, covering. Removing any foreign objects by rinsing, disinfecting the wound area and covering bandage. Covering; in improvised conditions we never clean the wound and do not remove any foreign object from it.

44. Treatment of wounds and fractures fixation of the afflicted by the accident is in the first aid performed:

always if there are gaping (deep) wounds and/or open fractures. only after the afflicted is out of vital functions malfunction danger. always as a priority on any wound or fracture.

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

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

46. Choose the true statement about heat loss after an injury:

Maintaining body temperature is one of the most energy-intensive vital processes. Fight against heat loss therefore belongs - especially with severe injuries - amongst life-saving acts with high priority. Mild hypothermia is in terms of first aid advantageous because it inhibits the metabolic processes and thus slows the onset of shock. Severe and prolonged hypothermia is harmful, preventing heat loss is therefore of particular importance for injuries in the winter and in poorly accessible terrain. Preventing heat loss is especially important because possible hypothermia is unpleasant and stressful for the afflicted. But this is not the priority for first aid.

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

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

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

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. If we witness an accident, we call emergency service after a thorough examination, to make sure that the situation is really serious.

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

an inspection of afflicted "head to toe" in order to uncover any injury changes on body. the second (and next) control examination to determine if there is a deterioration in the status. an examination by another independent person to verify the initial conclusions.

50. Choose the true statement about a position of a serious injury afflicted:

If the afflicted person actively takes some position, we do not prevent it. If the afflicted is communicating he should always be placed into position on the side (the "stabilized" or "recovery" position). If the afflicted is unconscious, he should always be placed in "anti-shock" position with legs and arms raised as high as possible to restore blood flow to the brain.
