Test - PL A

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

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

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

3. In a normal steady flight:

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

4. The chord is:

the curve that is halfway between the upper and lower surfaces of the aerofoil. the imaginary straight line joining the leading and trailing edges of the aerofoil. the straight line dividing the aerofoil in the middle of its thickness into two equal parts.

5. The aerodynamic drag is a sum of:

parasitic drag and supportive drag. parasitic drag, form drag, interference drag and rolling drag. form drag, friction drag, induced drag and interference drag.

6. Turbulent flow is:

the flow of air particles in different directions. the flow of air particles in the same direction. when the air particles are not moving.

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

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

8. Larger part of lift is generated:

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

9. An aircraft is flying at a very warm day across the Alps. The weather is good and there is an anticyclone in the area. The aircraft is flying by a mountain at the hight of its summit. What value is the altimeter showing compared to the summit altitude?

A lower height than the summit altitude. The same height as the summit altitude. A higher height than the summit altitude.

10. The boundary between two air masses, with the weather in one air mass significantly differing from the weather in the other air mass is called:

Air masses boundary. Front. Weather boundary.

11. The basic cause of mechanical turbulence is:

the air mass humidity and temperature. the air mass stratification. wind and configuration of terrain.

15. Air density:

increases with decreasing air temperature. decreases with decreasing air temperature. increases with increasing air temperature.

16. Ridge soaring is practiced so that:

we fly alongside a slope at its windward side turning 180° into the wind at the turn points. 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.

17. 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 canopy always tends to collapse and therefore the pilot must brake. the glider usually tends to collapse and therefore the pilot should break a bit before turning.

18. When entering a downdraft:

the canopy tilts backwards and can shoot forward afterwards. the canopy shoots forward and there is a danger of frontal collapse. the canopy tilts sidewards and can get asymmetric collapse.

19. B-stall is performed by:

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

20. I increase the flight speed by:

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

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

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. weight shift into the non collapsed side and light break of the same side to keep the glider in straight flight.

22. The globe is:

ideal sphere. a rotating ellipsoid flattened at the poles. a net of coordinate lines.

23. An aircraft on bearing 265 in a wind 085 is flying:

perpendicularly to the wind from left. with the wind. against the wind.

24. When performing comparative orientation it is always more reliable:

to locate and identify several landmarks. to carefully view the terrain below the aircraft. to focus on one landmark.

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

Paris. Moscow. London.

26. Geographic coordinates indicate:

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

27. 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 watch. accurate compass.

28. For emergency landing You would prefer:

water. trees. buildings.

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

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

30. If I stall the glider:

I use the reserve parachute; if there is not enough hight, I release the steering quickly. I release the steering continuously. I use the reserve parachute; if there is not enough hight, I hold the steering down firmly.

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

electric wires. water surface. a parking.

32. For emergency landing a pilot would rather choose:

dense forest. a lonely tree. a forest road.

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

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. I prepare for the landing on the rescue, nothing else can be done anyway.

34. The definition of visibility is:

the ability to see and recognize outstanding unlighted objects by day and lights at night from the cockpit of the aircraft in flight. the ability to see forward from the cockpit of the aircraft in flight determined by meteorological conditions and expressed in units of distance. the ability to see and recognize outstanding unlighted objects by day and lights at night determined by atmospheric conditions and expressed in units of distance.

35. To indicate the height after passing through the transition altitude the setting goes from QNH values:

to the altimeter setting at the value of 1013.2 hPa and vertical positions of the aircraft are expressed in flight levels. to the altimeter setting at QFE of the target airport and vertical positions of the aircraft are expressed in hight over the target airport. to the altimeter setting at QFE and vertical positions of the aircraft are expressed as hight above the ground.

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. To prevent heat loss the most effective is:

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

44. The helmet of the afflicted:

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. must never be taken off.

45. Choose the true statement about a position of an unconscious afflicted:

The unconscious afflicted must not be moved to eliminate the risk of further spine and spinal cord damage. The unconscious injury afflicted should always be placed on his back with his head tilted back. If the afflicted is reliably breathing in the current position, we leave him in this position.

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

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

47. 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.

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

49. After applying tourniquet the wound is still bleeding:

The tourniquet needs tightening. Loosen the tourniquet and lift the afflicted limb up. We need to use another compress bandage.

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

Removing any foreign objects by rinsing, disinfecting the wound area and covering bandage. Desinfecting the wound (in emergency using even concentrated alcohol), removing any foreign objects, covering.
