16. When entering a thermal current:

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

17. The heading of aircraft and its direction of movement compare to ground is:

the same when flying in no wind or exactly against the wind or with the wind. the same when flying in no wind or with the wind exactly from left or right. always the same.

21. 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.

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.

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

a parking. electric wires. water surface.

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

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

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

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

33. During ground handling training the glider lifts the pilot above the ground in a wind gust unexpectedly. The correct procedure is:

to pull the steering fully. to pull and release the steering repeatedly and by such flapping go back to the ground. to release the steering and fly, steer and land back to the ground.

34. A pilot must always have:

a proof of identity, a pilot's license or a student document, the airworthiness certificate, a proof of insurance for damage caused the aircraft operation, medical certificate of flying eligibility. a pilot's license or a student document, the airworthiness certificate, a proof of insurance for damage caused the aircraft operation, medical certificate of flying eligibility. a proof of identity, a pilot's license or a student document, the technical certificate of the aircraft, a proof of insurance for damage caused by the aircraft operation.

35. Airport operations are:

all flying aircrafts and aircrafts on the aerodrome operational area. all traffic at the aerodrome area and all aircrafts flying in the vicinity of the airport. all vehicles and persons operations on the aerodrome area.

36. The aircraft, that is obliged by the rules to give way to another aircraft, must:

avoided so that the maintained vertical distance between aircrafts was 150 m. avoid by flying above or under or cross the other aircraft flight line at a sufficient distance. avoided so that the maintained horizontal distance between aircrafts was 300 m.

37. The paraglider canopy is damaged mostly by:

storage in dark and dry rooms. UV rays, mechanical abrasion and humidity. mice and other wild rodents.

a circle with a radius of 3 NM (5.5 km), vertically from the ground to an altitude of 4000 feet (1200 meters). a circle with a diameter of 3 NM (5.5 km), vertically from the ground to an altitude of 4000 feet (1200 meters). a circle with a diameter of 5.5 NM (10 km), vertically from the ground to an altitude of 4000 feet (1200 meters).

40. Restricted air space (LK R):

must be passed through. must not be passed through. can be passed through under specified conditions.

41. Initial examination includes:

vital functions check according to the chart A-B-C. finding the circumstances of the incident, the patient's problems and possible diseases which he is suffering. fast check of the afflicted „from head to toe” with emphasis on injury signs.

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. During an unsuccessful landing a pilot flew through a window and cut his wrist so badly that the wound is heavily bleeding, blood squirts. 10 cm long piece of broken glass projects from the wound. The afflicted person is conscious, pale, complaining of pain in his right ankle which is evidently deformed. We'll call an ambulance and:

put the afflicted in a semi sitting position, pull out the sherd and apply compressing bandage. lay the afflicted down on his back with legs lifted, apply a tourniquet on his forearm tightening it gently. We do not pull out the piece of glass on principle. fix the leg, lay the afflicted in the anti shock position, lift the wounded hand up and if the bleeding doesn’t stop, apply a compressing bandage.

44. 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.

45. Choose the true statement about tactics when you are a witness of a severe injury:

First, you need to restore vital functions as quickly as possible, and only then deal with calling for help. If we witness an accident, we call emergency service after a thorough examination, to make sure that the situation is really serious. Before calling an emergency service it is appropriate to make at least indicative examination where the accident happened, what happened and how many affected there are.

46. To prevent heat loss the most effective is:

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

47. After applying tourniquet the wound is still bleeding:

We need to use another compress bandage. Loosen the tourniquet and lift the afflicted limb up. The tourniquet needs tightening.

48. In improvised conditions fracture fixing is:

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

49. A pilot should have his mobile phone:

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

50. Resuscitation can be (among others) terminated:

if it has reliably been found that the afflicted is older than 70 years. after 20 min of performing it without any obvious effect. when consciousness is restored - the patient begins to respond.
