6. How the speed system works?

It decreases the angle of attack by pulling the front risers. Sometimes it deforms the aerofoil shape. It decreases the angle of attack by releasing the rear risers. It increases the angle of attack by pulling the front risers.

7. Lift arises when an aerofoil is in flow due to the creation of a pressure differential above and below the aerofoil. What is the pressure below and above the aerofoil and what is the ratio of their sizes at normal angles of attack?

There is overpressure below the aerofoil and negative pressure above the aerofoil in the ratio of 1/3 of overpressure and 2/3 of negative pressure. There is overpressure below the aerofoil and negative pressure above the aerofoil in the ratio of 1/3 of overpressure and 2/3 of negative pressure.

24. Time of sunrise and sunset varies:

with annual periods. depending on the intensity of sunlight. influenced by the magnetic field of the Earth.

25. The prime meridian is:

the meridian, at which the latitude and longitude equal 0. meridian, also called the base meridian, passing through Greenwich Observatory in England. a meridian not passing through observatory in Greenwich, but only a small circle.

26. 225 degrees is direction:

south west. north west. south east.

27. Which of the following conditions is the most important for comparative navigation?

Experience of the pilot and his estimation. Navigational preparation before flight, map, visibility of ground. A good map and navigation skills of the pilot.

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

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

29. When flying on speed system:

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. The paraglider is prone to symmetrical or asymmetrical collapses.

32. During flight a pilot should have his cellphone (if it is available):

in a place, where he can reach it by any hand from the flying position. in the back harness pocket so it could not break or harm the pilot in case of accident. in any place, because he cannot telephone during flight anyway.

33. The best when blown behind a ridge is: Při přefouknutí přes kopec je nejbezpečnější

We do not pull out the piece of glass on principle. put the afflicted in a semi sitting position, pull out the sherd and apply compressing bandage. 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.
