2. The separation of streamlines is when:

the streamlines leave the aerofoil after copying its shape. the airflow becomes detached from the surface of the aerofoil. turbulent flow around the upper surface of the wing switches to laminar flow.

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

7. 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.

8. The main cause of the stall is always:

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

negative hight, so called dephtines. declination. alitude.

28. 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.

29. The reserve parachute is used so that:

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. Pull the rezerve parachute handle; when the needles are torn out, the reserve parachute opening system is activated.

30. The best when blown behind a ridge is: Při přefouknutí přes kopec je nejbezpečnější

to use a reserve parachute which is more stable in turbulences. 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.

31. Use the reserve parachute without hesitating:

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

32. For emergency landing You would prefer:

buildings. trees. water.

33. 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.

34. TMA (Terminal Control Area)

41. 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.

42. Risers are:

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

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.). is never to be removed - cover the wound with anything in it and soak the bandage with disinfection. must be removed even if surrounding tissue is damaged and then the wound needs rinsing with disinfection.

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

1210 155 112

45. Choose the true statement about heat loss after an injury:

Mild hypothermia is in terms of first aid advantageous because it inhibits the metabolic processes and thus slows the onset of shock. Severe and prolonged hypothermia is harmful, preventing heat loss is therefore of particular importance for injuries in the winter and in poorly accessible terrain. Preventing heat loss is especially important because possible hypothermia is unpleasant and stressful for the afflicted. But this is not the priority for first aid. Maintaining body temperature is one of the most energy-intensive vital processes. Fight against heat loss therefore belongs - especially with severe injuries - amongst life-saving acts with high priority.

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

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. If there is serious injury, everybody is obliged to provide first aid; this assistance must not endanger the life or health of the firstaider.

47. To prevent heat loss the most effective is:

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

48. The helmet of the afflicted:

should be taken off by pulling in the long axis of the body with permanent fixation of the head and neck. should be taken off only by gente tilting nad twisting. must never be taken off.

49. If improvised transport of an insured PG pilot is necessary (for example in difficult terrain), as the best means of transport will serve:

his paragliding harness. into a stretcher tied straight branches. the canopy folded in a suitable rectangular shape.

50. A pilot should have his mobile phone:

placed so that it could be reached in any position of pilot’s body. switched off because the aviation regulations forbid the use of mobile phones in flight. placed in the pocket of the harness so that it could not cause any injury in case of an accident.
