Question 1

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 2

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

Answer

D

Answer

B

Answer

Answer

30 km

Answer

45 NM

Answer

Question 5

The total weight of an aeroplane is acting vertically through the...

Accepted Answer

Centre of gravity

Answer

Stagnation point

Answer

Centre of pressure

Answer

Neutral point

Question 6

The upper limit of LO R 16 equals... See annex (PFP-056)

Accepted Answer

1 500 ft MSL

Answer

1.500 ft GND

Answer

1 500 m MSL

Answer

FL150

Question 7

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 8

During a cross-country flight, you approach a downwind turning point. The point should be taken...

Accepted Answer

As high as possible

Answer

As low as possible

Answer

As steep as possible

Answer

With as little bank as possible

Question 9

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 10

The term "centre of gravity" is defined as...

Accepted Answer

The point at which the total mass of the aeroplane is considered to act

Answer

The heaviest point on an aeroplane

Answer

Half the distance between the neutral point and the datum line

Answer

Another designation for the neutral point
