28. Use the reserve parachute without hesitating:

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

29. If a pilot is being dragged by strong wind along the ground, he should:

wait until the glider stops itself. pull the A risers or lines. pull the steering lines or rear lines/risers.

30. When flying on speed system:

The paraglider will increase its speed and it will be more stabile thanks to better flow. 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.

31. Your special equipment for safety maneuvers training should be:

a life jacket and a flare. a life jacket, a hook knife for cutting lines or risers. a life jacket, an orange helmet and light shoes.

32. 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 pulling the steering on the not collapsed side quickly and fully to help the regeneration of the canopy. no sudden piloting inputs; a certified paraglider will return into straight flight itself.

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

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

34. Flying a paraglider is allowed:

from sunset to sunrise. in VFR conditions during a day; a day is considered as a time period between sunrise and sunset. only during a day, which means between morning civil twilight and evening civil twilight or in a similar period of time which can be designated by a competent authority.

46. "Secondary examination" of an injury afflicted means:

an inspection of afflicted "head to toe" in order to uncover any injury changes on body. the second (and next) control examination to determine if there is a deterioration in the status. an examination by another independent person to verify the initial conclusions.

47. If one layer of pressure bandage is not enough to stop bleeding from a wound on leg:

We apply another 1 or 2 layers or, if still not enough, use a tourniquet. We urge the arrival of emergency services and re-emphasize the urgency of the case. We take off the old bandage and apply a new one and tighten it better.

48. 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.

is never to be removed - cover the wound with anything in it and soak the bandage with disinfection. 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.
