16) The angle of attack for a propeller blade is the angle between blade chord line and: Report

Aeroplane heading.

Principal direction of propeller blade.

Local air speed vector.

17) What happens during an engine failure with two similar aeroplanes with wing mounted engines, one of them with jet engines, the other one with co-rotating propellers: Report

The same yaw tendency for both aeroplanes regardless of left or right engine failure.

The same roll tendency for both aeroplanes.

More roll tendency for the propeller aeroplane.

18) Which of the following statements about dihedral is correct? Report

The "effective dihedral" of an aeroplane component means the contribution of that component to the static lateral stability.

Effective dihedral is the angle between the 1/4-chord line and the lateral axis of the aeroplane.

Dihedral contributes to dynamic but not to static lateral stability.

19) One of the requirements for dynamic stability is: Report

a small C.G. range.

effective elevator.

positive static stability.

20) With increasing altitude and constant IAS the static lateral stability (1) and the dynamic lateral/directional stability (2) of an aeroplane with swept-back wing will: Report

(1) decrease (2) decrease.

(1) decrease (2) increase.

(1) increase (2) decrease.
