Test - PL A

1. At the critical angle of attack:

the lift coefficient reaches its maximum values, over further increasing of the angle of attack the lift coefficient decreases abruptly. the lift coefficient sharply increases. the drag coefficient drops abruptly.

2. In a steady gliding flight there is a balance between:

lift and drag. thrust and weight, drag and lift. gravity force and lift plus drag.

3. The dynamic stability of a paraglider means:

that if unbalanced it is not completely returning into steady flight. that if unbalanced it returns into steady flight. that it is easy to steer, especially in aerobatics.

4. Glide ratio is influenced only by:

the angle of attack (i.e. lift and drag coefficients). total weight. the velocity of flow.

5. If the angle of attack increases, the forward speed:

stays the same. decreases. increases.

6. The lift on the aerofoil:

is generated by the Coriolis force and by equalizing pressure above and below the aerofoil. is created due to different speed of flow above nad below the aerofoil. is created due to angle of attack and change of air temperature above and below of the wing.

7. When the surface load changes the glide ratio:

does not change because the relation between lift coefficient and drag coefficient does not change. changes because the relation between lift and drag does not change. changes because effective bearing area is the same.

8. There are aerodynamic forces generated on a body in flow. They are called:

lift, mass and drag. the resultant aerodynamic force which is sum of lift and drag. lift and overpressure.

29. 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 do big ears which will help to fly through turbulences by increasing surface load of the wing. to fly with the wind as far as possible to a possible emergency landing field.

30. For emergency landing You would prefer:

water. trees. buildings.

31. When sucked in a vertically developed cloud the best to do is:

to steer the glider straight into the lightest part of the cloud. to keep circling through the cloud as high as possible and so fly over it. to perform the most effective escape maneuver and try to keep flying against the wind.

32. Before a landing into still water it is necessary:

to undo the harness buckles so it was possible to leave it at the moment of contact with water. to jump out of the harness about 3 to 5 m above the water surface. to turn the glider against the wind.

33. 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.

34. Upper limit of G class airspace is in:

300 m AMSL 300 m AGL 300 m STD

35. When two light aircrafts are flying on intersecting tracks in free space, the right of way is of the light aircraft flying:

against the sun. from the right. from the left.

36. Two of the same category aircrafts are flying in one track against each other. Na vstřícné trati letí letadla stejné kategorie. Actions of avoidance are:

Both aircrafts will change their curse to the right. You will turn to the right, the other aircraft will turn to the left. Both aircrafts will change their curse to the left.

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

The aircraft commander has not the right to take a final decision on the execution of the flight. 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 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.

42. 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.

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

If we witness an accident, we call emergency service after a thorough examination, to make sure that the situation is really serious. First, you need to restore vital functions as quickly as possible, and only then deal with calling for help. 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.

timely starting and continuity of compressions. the highest possible frequency of compressions. the deepest compressions.

46. Choose the true statement about a position of a serious injury afflicted:

If the afflicted is communicating he should always be placed into position on the side (the "stabilized" or "recovery" position). If the afflicted person actively takes some position, we do not prevent it. If the afflicted is unconscious, he should always be placed in "anti-shock" position with legs and arms raised as high as possible to restore blood flow to the brain.
