Test - PL A

1. The resultant aerodynamic force consists of:

lift and drag. lift and weight. lift coefficient and weight.

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

it will fly 6 km far from the altitude of 1 km. it will fly 1 km far from the altitude of 6 km. its velocity is 6 m/s.

3. When an aircraft is flying with such an angle of attack that its gliding ratio is ', it means that:

it will fly 10 km far from altitude 1 km in no wind. it is flying under an angle 10° towards the ground. it will fly 1 km in 10 s.

4. 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.

5. The lift on the aerofoil is created by:

the force of flowing air from front of the aerofoil (when the angel of attack is positive). 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. 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.

6. Spiral is a flight mode when:

the air flow doesn’t detach from the aerofoil. the flow gets separated from the aerofoil on the inner side of the turning wing. the flow gets separated from the aerofoil on the outer side of the turning wing.

7. 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.

8. 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.

9. Wind is given by:

the direction from which it blows and speed. speed. the direction towards what it blows and speed.

10. Which type of precipitation comes off water only containing clouds at mid-latitudes?

12. Anabatic flow is:

a gusty mountain breeze. the land breeze. the wind coming up the mountain slopes due to thermic.

13. The most common wind direction in the valley caused by thermal effects is:

during the night towards the hill. during the day towards the hill. during the day down the hill.

14. Increasing distance between isobars means that in the given area the air velocity will be:

the distance between isobars tells nothing about the air velocity. faster. slower.

15. Mass storms occur:

mostly in the afternoon and evening in the hours of the highest ground temperatures. anytime. mostly during the night.

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

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

17. What does the term „spin” mean?

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

18. 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.

19. I increase the flight speed by:

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

20. 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. 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.

21. Spiral is performed by:

pulling at first both the brakes and then loosening one brake all the way up while the other pulling completely down - the paraglider descends circling in a dynamic and fast rotation. weight shift in the intended turning side, pulling the steering on that side and pulling down the front riser on the other side. a smooth transition from a turn into sharper and sharper turn via gradually increased brake input and body weight shift in the same side in which turning.

22. 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.

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

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

24. Geographical meridian is:

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

25. Magnetic north is a direction given by:

measurements on a map. the compass needle free of any interferences. the theoretical line intersecting the earth center and the surface of the earth in points called magnetic north and magnetic south.

26. The most suitable maps for aeronautical navigation are:

the maps which truly reflect the topographic situation and angles. maps with 1 : 500 000 scale. those with precise angles.

27. The globe is:

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

28. In mid-air collision about 50 to 100 m above the terrain the correct procedure is:

stalling the glider and so clear the contact with the other aircraft. using the reserve parachute. to execute a descending maneuvre.

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

to perform the most effective escape maneuver and try to keep flying against the wind. 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.

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

a parking. electric wires. water surface.

31. When flying on speed system:

The paraglider is prone to symmetrical or asymmetrical collapses. 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.

32. 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.

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

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

34. Except for takeoff or landing, or except by permit issued by the Aviation Authority, a VFR flight must be conducted over the congested areas or gathering of people in the open air at a height that may not be less than:

150 m above the highest obstacle within a radius of 600 m from the aircraft. 300 m above the highest obstacle within a radius of 600 m from the aircraft. 300 m above the highest obstacle within a radius of 300 m from the aircraft.

43. Choose the true statement about the obligation to provide first aid:

If there is serious injury, everybody is obliged to provide first aid; this assistance must not endanger the life or health of the firstaider. The obligation to provide first aid is only moral and it is not legally enforceable. Everyone who witnesses an accident is obliged to provide first aid, regardless of the severity of injury and danger.

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

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

45. "Gasping breaths" mean:

noticeably noisy breaths in fast pace; these breaths are typical for developing shock-like state. noticeably fast but quiet and shallow breathing, typical for a patient with an airway obstruction. individual breaths in noticeably long intervals by the unconscious afflicted; these breaths are typical for cardiac arrest.
