Test - PL A

1. Lift is:

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

2. The paraglider glide ratio is defined as:

the ratio between the horizontal and vertical velocity component of the paraglider. the weight and lift ratio. the relation between the glider performance and vertical speed.

3. A paraglider stall occures when:

the speed system is pushed too fast. the pilot breaks too much. the glider overcomes the pilot when taking off.

4. 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.

5. The centre of gravity of an aircraft:

is a point where the resultant aerodynamic force and force of gravity acts. is a point where the force of gravity acts. is a point where the resultant aerodynamic force acts.

6. Which of the following pilot inputs increases the angle of attack?

Releasing the steering. Pushing the speed system. Pulling the steering.

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

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

8. The lift on the aerofoil:

is created due to different speed of flow above nad below the aerofoil. is created due to angle of attack and change of air temperature above and below of the wing. is generated by the Coriolis force and by equalizing pressure above and below the aerofoil.

9. Which of the following types of cloud is considered low level cloud?

7000 m MSL 5500 m MSL 3000 m MSL

11. Cooling speed of rising air saturated with water vapor is less than of unsaturated air because:

water vapor absorbs heat radiated by air. condensation releases heat. water vapor is not cooled as fast as dry air.

12. Saturated adiabatic curve is showing the change in temperature with height of value:

0,65 °C / 100 m of hight. 1,00 °C / 100 m of hight. 0,60 °C / 100 m of hight.

13. 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.

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

Drop of temperature with altitude. Isothermy. Inversion.

15. The part of cyclone between the warm and cold fronts is called:

the ridge of higher pressure. the front line. the warm sector.

16. 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.

17. 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.

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

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

19. What does the term „spin” mean?

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

20. 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.

21. When entering a thermal current:

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

22. 10 cm in map with 1 : 200 000 scale refers of real distance:

200 km 20 km 50 km

23. 225 degrees is direction:

north west. south west. south east.

24. Time of sunrise and sunset varies:

influenced by the magnetic field of the Earth. with annual periods. depending on the intensity of sunlight.

25. Comparative navigation involves:

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

26. Direction south is reported by:

090° 360° 180°

27. 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.

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

He should fly with sidewind or windwards as the terrain allows as far as possible to an alternative landing field. 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.

29. Use the reserve parachute without hesitating:

in rapid uncontrolable rotation. after being blown behind a mountain ridge. under a Cumulonimbus cloud.

30. For emergency landing a pilot would rather choose:

a lonely tree. dense forest. a forest road.

31. 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.

32. The reserve parachute is used so that:

Pull the rezerve parachute handle; when the needles are torn out, the reserve parachute opening system is activated. Pull the reserve parachute from the harness and throw it into a free space letting go the handle too. By pulling the handle the reserve parachute is activated; the handle can be lost.

33. After an asymmetric collapse the correct procedure is:

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. pulling the steering on the not collapsed side quickly and fully to help the regeneration of the canopy.

34. Restricted air space (LK R):

must not be passed through. can be passed through under specified conditions. must be passed through.

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

36. To recalculate a figure in meters into figure in feet we use the simplified formula:

(m x 3) + 10% (m : 10) x 3 (m x 3) : 10

37. The upper limit of class E airspace is:

FL 85 (2600 m) FL 125 (3800 m) FL 95 (2900 m)

38. A proof of liability insurance must be on board during all flights.

Not during an airport flight. Yes. No.

39. An aircraft having priority must maintain its course and speed:

The course must be kept but speed can be changed. These conditions must not be changed. This rule does not relieve the aircraft commander of responsibility to carry out such measures that will the best prevent a collision.

40. Who is authorized to check a pilot's license or student document?

Paragliding operations inspector and Paragliding technical inspector of LAA CR, a person authorized by the Ministry of Transport or the CAA of the CR, Czech Police.

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

43. The telephone number of medical emergency service in the Czech Republic is:

155 158 150

44. „Surgical” rubber gloves:

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

45. Clearing the airway of unconscious patient is done primarily using:

forward head tilt. stabilised position. backward head tilt.

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

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

155 1210 112
