Test - PL A

1. 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 and overpressure. lift, mass and drag.

2. 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.

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. 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 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.

5. The lift coefficient is influenced the most by:

the air foil curving. the air foil thickness. the speed of flow.

6. The lift acts:

always perpendicularly to the chord. always perpendicularly to the direction of flow attacking the aerofoil. always upwards from the aerofoil.

7. Surface load:

indicates the number of m2 of bearing area per one kilogram of the total weight. indicates the number of kilograms of the pilot weight per m2 of bearing area. indicates the number of kilograms of the total weight per m2 of bearing area.

8. The angle of attack is:

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

9. Among the clouds with a great vertical development is:

Cb – cumulonimbus Ac – altocumulus Cc – cirocumulus

10. What will be the surface wind characteristics in the area where on the surface meteorological map there are isobars close together?

Strong wind blowing perpedicularly to the isobars. Weak wind blowing along the isobars. Strong wind blowing approximately along the isobars.

11. Turbulence is defined as:

forces acting on the aircraft in different directions and giving this aircraft various supplementary accelerations. forces acting on the aircraft in vertical directions. forces increasing the aircraft’s velocity.

12. The character of precipitation falling out of Cb - cumulonimbus type clouds is:

drizzle. persistent rainfall. strong showers.

13. Low level cloud can be:

Ci – cirrus Ac – altocumulus St – stratus

14. The air mass is called unstable if there are:

stratified clouds in it. convective vertical motions in it. inversions in it.

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

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

16. B-stall is performed by:

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

17. Ridge soaring is practiced so that:

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

18. When entering a downdraft:

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

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

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

20. I increase the flight speed by:

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

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

Three. Five. Seven.

22. Magnetic course is measured:

from bearing indicator. from prime meridian. from geographical north of local meridian.

23. Magnetic north is a direction given by:

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

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

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

25. The prime meridian is:

a meridian not passing through observatory in Greenwich, but only a small circle. meridian, also called the base meridian, passing through Greenwich Observatory in England. the meridian, at which the latitude and longitude equal 0.

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

alitude. negative hight, so called dephtines. declination.

27. Course is measured in degrees from north:

clockwise to the east and counterclockwise to the west. counterclockwise. clockwise.

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

turning only in the side where the steering line is OK. 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.

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

a parking. electric wires. water surface.

30. 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.

31. For emergency landing You would prefer:

water. trees. buildings.

32. When landing in water surface a pilot should steer the glider:

with the wind. against the wind. with the wind from a side.

33. If I stall the glider:

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

34. The lower limit of a control zone (CTR) is formed by:

the upper limit of the G class air space. a specified altitude. the ground surface.

35. Can I meet an airliner in Class E airspace?

Only in clouds. No. Yes.

36. The AGL abbreviation by a height data in the airspace map means:

the hight according the local atmospheric pressure. the hight above the see level. the hight above the ground level.

37. Verifying whether a paraglider technical certificate is valid is a duty of:

the aircraft commander (pilot). the operator. the head of air traffic.

38. The dangerous airspace (LKD) is is an area where flying is:

prohibited. restricted. dangerous.

39. 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.

40. The upper limit of class E airspace is:

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

41. Initial examination includes:

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.

42. A paraglider is the most damaged by:

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

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

stabilised position. forward head tilt. backward head tilt.

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

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. The unconscious afflicted must not be moved to eliminate the risk of further spine and spinal cord damage.

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

158 155 150

46. Unless prevented by special circumstances, the best for the accident afflicted is:

the "Anti-shock" position with legs and arms raised as high as possible„ a position on the side („stabilized” or „recovery” position). a position that the afflicted person wants to take.

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. Fractures of lower limbs are preferably fixed by:

hanging in a triangular bandage. tightening to the other limb (only if that is not broken too). using an improvised splint (branch, stick, etc.).

49. 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.

50. Choose the true statement about using the thermal („space”) blanket:

The foil is a very good thermal isolation but does not protect against moisture - it can leak in strong rain. The side doesn’t matter, the important is to wrap it tightly all around the patient. This blanket can be also used as a tourniquet or improvised bandage.
