Test - PL A

1. At the critical angle of attack:

the lift coefficient sharply increases. the lift coefficient reaches its maximum values, over further increasing of the angle of attack the lift coefficient decreases abruptly. the drag coefficient drops abruptly.

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

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

3. When a paraglider is in steady flight in an ideal environment (no wind) at a glide ratio 6, then it means that:

the lift of the paraglider is 6 times less then its drag. it is flying at the speed of 6 m/s and the lift of the paraglider is 6 times greater then its drag. the lift is 6 times greater then the drag.

4. What kind of change of flow speed and static pressure causes the widening of streamlines in a specified place?

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

5. Induced drag:

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 parasitic energy induced by air rfiction around an aircraft. arises as a result of interference between flows around different parts of an aircraft.

6. The separation of streamlines is when:

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

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

gravity force and lift plus drag. lift and drag. thrust and weight, drag and lift.

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

no inputs in steering letting the glider reinflate. 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.

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

23. Geographical meridian is:

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

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

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

25. Comparative navigation involves:

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

26. Geographic coordinates indicate:

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

27. Direction south is reported by:

180° 090° 360°

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

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

29. 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.

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

31. Your last choice for emergency landing would always be:

a parking. electric wires. water surface.

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

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. to fly with the wind as far as possible to a possible emergency landing field.

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

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

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

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

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

37. The paraglider canopy is damaged mostly by:

38. Flying a paraglider is allowed:

only during a day, which means between morning civil twilight and evening civil twilight or in a similar period of time which can be designated by a competent authority. from sunset to sunrise. in VFR conditions during a day; a day is considered as a time period between sunrise and sunset.

valid AIP or ICAO map. official CAA map. ADAC map.

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

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

43. 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. to stop heavy bleeding, clearing the airway and fight against heat loss. gentle transportation to the place of professional help.

44. Choose the true statement about improvised transport:

Unless it is necessary the patient should not be transported before the arrival of professional assistance. 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.

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

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

46. If it is obvious that the action of rescue helicopter is necessary, in the Czech Republic it is preferably needed to call number:

155 112 1210

47. „Surgical” rubber gloves:

should be used only in treatment of heavy bleeding or dirty wounds. should be used for taking care of any injury. are suitable for treatment of patients suspected of infectious disease.

48. A paraglider in a spin fell nearby. On our approach he lies on his back, unconscious, not breathing, bluish. No clearly visible injury is obvious. We'll call an ambulance and firstly:

lay the afflicted in the anti-shock position with head underlaid. lay the afflicted in the stabilized position. free the airway by backward head tilt.

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

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

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

they were always in the visual field of the helicopter pilot. 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.
