Accepted Answer

Balance arm

Answer

Lever

Answer

Torque

Answer

Span width

Question 2

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 3

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

Question 5

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 6

While planning a cross country gliding flight, what ground structure should be avoided en route?

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 7

The angle of descent is defined as...

Accepted Answer

The angle between a horizontal plane and the actual flight path, expressed in degrees [°]

Answer

The ratio between the change in height and the horizontal distance travelled within the same time, expressed in percent [%]

Answer

The angle between a horizontal plane and the actual flight path, expressed in percent [%]

Answer

The ratio between the change in height and the horizontal distance travelled within the same time, expressed in degrees [°]

Question 8

The empty weight and the corresponding centre of gravity (CG) of an aircraft are initially determined...

Accepted Answer

By weighing

Answer

By calculation

Answer

For one aircraft of a type only, since all aircraft of the same type have the same mass and CG position

Answer

Through data provided by the aircraft manufacturer.

Question 9

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

Question 10

Which factor shortens landing distance?

Accepted Answer

Strong head wind

Answer

Heavy rain

Answer

High pressure altitude

Answer

High density altitude
