Answer

A

Question 6

Unless the aircraft is equipped and certified accordingly...

Accepted Answer

Flight into known or forecast icing conditions is prohibited. Should the aircraft enter an area of icing conditions inadvertently, it should be left without delay

Answer

Flight into forecast icing conditions is prohibited. Should the aircraft enter an area of icing conditions inadvertently, the flight may be continued as long as visual meteorological conditions are maintained

Answer

Flight into known or forecast icing conditions is only allowed as long as it is ensured that the aircraft can still be operated without performance degradation

Answer

Flight into areas of precipitation is prohibited

Answer

1.500 ft AGL

Answer

1.500 ft AGL

Answer

1.500 ft MSL

Question 8

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

Accepted Answer

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

Answer

Distance of a mass from the center of gravity

Answer

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

Answer

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

Question 9

The empty weight and the corresponding center 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
