is lower in higher altitudes then in lower altitudes. is higher in higher altitudes then in lower altitudes. is the same in all altitudes.

13. The speed of a thermal current depends on:

uneven heating of cyclonic thermal convective clouds. instability rate and air warming from the ground surface. time of day and season.

14. Condensed isobars on the synoptic map indicate:

greater pressure difference and therefore stronger wind. high temperature difference. pressure level of the area.

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

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

16. Spiral is performed by:

weight shift in the intended turning side, pulling the steering on that side and pulling down the front riser on the other side. a smooth transition from a turn into sharper and sharper turn via gradually increased brake input and body weight shift in the same side in which turning. pulling at first both the brakes and then loosening one brake all the way up while the other pulling completely down - the paraglider descends circling in a dynamic and fast rotation.

17. Ridge soaring is practiced so that:

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. we soar the wind wave just above the mountain ridge turning 180° at the turn points no matter what direction.

18. When entering a thermal current:

the glider usually tends to collapse and therefore the pilot should break a bit before turning. the canopy always tends to collapse and therefore the pilot must brake. the glider informs the pilot by its movements about the strength of the lift and usually also about which direction is better to turn.

19. The take off control includes:

the check of canopy, carabiners, weather and space in the direction of flight and landing. the check of harness, lines, canopy, weather and space. the check of glider and harness wear and tear, stitching, carabiners, helmet and instruments.

the maps which truly reflect the topographic situation and angles. those with precise angles. maps with 1 : 500 000 scale.

27. Geographical North and South:

are influenced by the Earth’s magnetism. do not change location. change location depending on annual periods.

28. 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.

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. After a tall tree landing:

you should do maximum via reachable means to get professional rescue help (a cellphone or radio call, waiting for friends, whistle ect.) you should climb down as fast as possible to show that you are OK. you should wait until your friends come and then you climb down while they are ready to catch you if needed.

31. After an asymmetric collapse the correct procedure is:

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. 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

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. 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.

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

water surface. electric wires. a parking.

34. Flying above a gathering of people at such a height that would not allow a safe landing in case of danger without endangering pilots or people on the ground is:

allowed. possible only at an air show with a valid authorization issued. forbidden.

35. The pilot (aircraft commander) is in competence to:

to decide definitively on the execution of a flight. to obey an operator's decision on the execution of a flight. The pilot has no right to decide on the execution of a flight.

36. Except for takeoff or landing or except by permission issued by the Authority a VFR flight must be conducted above the ground or water at a height of not less than:

300 m 150 m except for ridge soaring. 150 m

37. Pilots must have the documents required for flying a light aircraft:

with them at flights outside the airport. with them at cross country flights. with them at every flight.

38. TMA (Terminal Control Area)

can be flown under. can be flown under only with a two way radio communication with AFIS. cannot be flown under or over.

39. Responsibility of the pilot (commander) of the aircraft:

The aircraft commander is responsible for execution of the flight under the rules of flying, let he alone controls the plane or not, except in cases when circumstances force a deviation from these rules in the interest of safety. The aircraft commander is not responsible for the execution of the flight when he received takeoff clearance from air traffic control services. The aircraft commander has not the right to take a final decision on the execution of the flight.

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

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

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. Risers are:

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

43. Chest compression during resuscitation is performed:

next to left nipple. by the lower end of chest bone. in the middle of chest bone.

44. The most essential first aid actions that can be performed in the event of serious accident are:

gentle transportation to the place of professional help. to stop heavy bleeding, clearing the airway and fight against heat loss. fixing the bone fractures, treatment of wounds and abrasions.

45. The first aid basics of wounds and abrasions treatment are:

Removing any foreign objects by rinsing, disinfecting the wound area and covering bandage. Covering; in improvised conditions we never clean the wound and do not remove any foreign object from it. Desinfecting the wound (in emergency using even concentrated alcohol), removing any foreign objects, covering.

46. In practice, we can recognize the malfunction of blood stream (cardiac arrest) by the fact that:

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

47. If the unconscious afflicted is not breathing:

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

48. In improvised conditions fracture fixing is:

necessary in case of open fracture. a priority first aid objective. needed in exceptional cases if manipulation with the patient before professional medical services arrival is necessary.

49. A paraglider in a spin fell nearby. On our approach he lies on his back, unconscious, not breathing, bluish. No clearly visible injury is obvious. We'll call an ambulance and firstly:

lay the afflicted in the anti-shock position with head underlaid. lay the afflicted in the stabilized position. free the airway by backward head tilt.

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

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. 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. 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.
