Test - PL A

1. Turning of a paraglider is the result of:

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

2. The resultant aerodynamic force consists of:

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

3. The lift on the aerofoil is created by:

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. 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).

4. Lift is:

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

5. The angle of attack is:

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

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

7. Where on the aerofoil the flow separation starts?

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

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

Only for tail wind. No. Yes.

9. Humidity means:

precipitation fall snowing the amount of water vapor in the air

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

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

11. The boundary between troposphere and stratosphere is called:

tropopause ionosphere atmosphere

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

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

13. Vertical robustness of the troposphere is the greatest:

over the equatorial regions. in the temperate zones. over the poles.

14. What vertical temperature stratification is typical for advection fog?

Isothermy. Inversion. Drop of temperature with altitude.

15. Wind is given by:

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

16. When entering a thermal current:

the canopy tilts sidewards and can get asymmetric collapse. the canopy shoots forward and can collapse. the canopy lilts backwards and can shoot forward afterwards.

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. 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.

19. 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 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.

20. The take off control includes:

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. the check of harness, lines, canopy, weather and space.

21. What does the term „spin” mean?

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

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

negative hight, so called dephtines. alitude. declination.

27. Which of the following conditions is the most important for comparative navigation?

A good map and navigation skills of the pilot. Navigational preparation before flight, map, visibility of ground. Experience of the pilot and his estimation.

28. After an asymmetric collapse the correct procedure is:

pulling the steering on the not collapsed side quickly and fully to help the regeneration of the canopy. weight shift in the not collapsed side of the glider and brake the same side slightly to stop rotation.maximálně se vyklonit na nezaklopenou stranu a také ji přibrzdit tak, aby nedošlo k rotaci no sudden piloting inputs; a certified paraglider will return into straight flight itself.

29. 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.

30. When flying on speed system:

The paraglider is prone to symmetrical or asymmetrical collapses. The paraglider will increase its speed and it will be more stabile thanks to better flow. The paraglider will increase its speed and will be more prone to symmetrical or asymmetrical collapses.

31. 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.

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

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

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 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.

43. A foreign object (e.g. little stone, sherd or so):

is to be removed from a wound if it is possible without excessive violence (e.g. rinsing with water, gently pulling etc.). must be removed even if surrounding tissue is damaged and then the wound needs rinsing with disinfection. is never to be removed - cover the wound with anything in it and soak the bandage with disinfection.

44. "Gasping breaths" mean:

50. 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 shade into semi sitting position and check him occasionally during flying. If his condition gets worse, we call help. We lay him in the anti-shock position with his feet up, cover him and call an ambulance.
