Question 1

The term "moment" with regard to a mass and balance calculation is referred to as...

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

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 3

What distance can be covered during a glide in a glider plane with glide ratio 1/30 from a height of 1500 m? (Neglect wind and thermal effects)

Accepted Answer

45 km

Answer

30 km

Answer

45 NM

Answer

81 NM

Question 4

Which factor shortens landing distance?

Accepted Answer

Strong head wind

Answer

Heavy rain

Answer

High pressure altitude

Answer

High density altitude

Question 5

Exceeding the maximum allowed aircraft mass is...

Accepted Answer

Not permissible and essentially dangerous

Answer

Compensated by the pilot's control inputs

Answer

Only relevant if the excess is more than 10 %

Answer

Exceptionally permissible to avoid delays

Question 6

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

Question 7

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 8

The required data for a mass and balance calculation including masses and balance arms can be found in the...

Accepted Answer

Mass and balance section of the pilot's operating handbook of this particular aircraft

Answer

Certificate of airworthiness

Answer

Performance section of the pilot's operating handbook of this particular aircraft

Answer

Documentation of the annual inspection

Question 9

The term "balance arm" in the context of a mass and balance calculation defines the...

Accepted Answer

Distance from the datum to the centre of gravity of a mass

Answer

Distance of a mass from the centre of gravity

Answer

Point on the longitudinal axis of an aeroplane or its extension from which the centres of gravity of all masses are referenced

Answer

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

Question 10

The centre of gravity has to be located...

Accepted Answer

Between the front and the rear C.G. limit

Answer

Behind the rear C.G. limit

Answer

In front of the front C.G. limit

Answer

Right of the lateral C.G. limit
