Accepted Answer

Product of a mass and a balance arm

Answer

Sum of a mass and a balance arm

Answer

Difference of a mass and a balance arm

Answer

Quotient of a mass and a balance arm

Question 2

After getting around a turning point, what should a glider pilot be prepared for?

Accepted Answer

For a changed cloud picture due to the apparently changed position of the sun

Answer

For weakening thermals due to the progressing time

Answer

For a changed horizontal picture due to lower cloud bases

Answer

For increased cloud dissipation due to the progressing time

Question 3

The centre of gravity (CG) defines...

Accepted Answer

The point through which the force of gravity is said to act on a mass

Answer

The point on the longitudinal axis or its extension from which the centres of gravity of all masses are referenced

Answer

The distance from the datum to the position of a mass

Answer

The product of mass and balance arm

Question 4

An aircraft must be loaded and operated in such a way that the centre of gravity (CG) stays within the approved limits during all phases of flight. This is done to ensure...

Accepted Answer

Both stability and controllability of the aircraft

Answer

That the aircraft does not exceed the maximum permissible airspeed during a descent

Answer

That the aircraft does not tip over on its tail while it is being loaded.

Answer

That the aircraft does not stall.

Question 5

Which factor shortens landing distance?

Accepted Answer

Strong head wind

Answer

Heavy rain

Answer

High pressure altitude

Answer

High density altitude

Question 6

What is the purpose of "interception lines" in visual navigation?

Accepted Answer

They are used as easily recognizable guidance upon a possible loss of orientation

Answer

They help to continue the flight when flight visibility drops below VFR minima

Answer

To mark the next available en-route airport during the flight

Answer

To visualize the range limitation from the departure aerodrome

Accepted Answer

Moist ground, water areas, marsh areas

Answer

Stone quarries and large sand areas

Answer

Highways, railroad tracks and channels

Answer

Areas with buildings, concrete and asphalt

Question 10

Baggage and cargo must be properly stowed and fastened, otherwise a shift of the cargo may cause...

Accepted Answer

Uncontrollable attitudes, structural damage, risk of injuries

Answer

Calculable instability if the C.G. is shifting by less than 10 %

Answer

Continuous attitudes which can be corrected by the pilot using the flight controls

Answer

Structural damage, angle of attack stability, velocity stability
