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.

28. When flying on speed system:

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

29. If one side of canopy is stalled, the pilot should:

release the steering continuously. hold down the already pulled steering and counter-steer the rotation by weight-shift. pull the second steering fully and then release both.

30. The reserve parachute is used so that:

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

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

turning only in the side where the steering line is OK. steering via weight shift and cautious pulling of the rear risers. steering by another suitable line and the other steering line or, if there is enough hight, use the reserve parachute.

32. Use the reserve parachute without hesitating:

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

He should keep flying against the wind and emergency-land in the terrain below him. 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.

the afflicted is unresponsive, does not breath or does only gasping breaths and does not move. we cannot feel the pulse at the carotid artery. we cannot feel the heart beating on the chest.

45. A pilot should have his mobile phone:

placed in the pocket of the harness so that it could not cause any injury in case of an accident. 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.

46. If the unconscious afflicted is not breathing:

First we try to free the airway. We start the resuscitation immediately. We promptly transport him to the professional medical service.

47. To prevent heat loss the most effective is:
