Question 1

In what flight phase are the outboard ailerons (if present) not operated ?

Accepted Answer

During cruise flight.

Answer

During a landing with strong and gusty crosswind to avoid overcontrolling the aeroplane.

Answer

In the approach phase, before landing.

Answer

During take-off, until lift-off.

Answer

Landing gear extended

Answer

Landing gear retracted

Answer

Flaps (and/or slats) extended or speed below a certain value

Accepted Answer

Square of the speed

Answer

Speed

Answer

Angle of attack

Answer

Square of the angle of attack

Question 10

Which statement is correct for a side slip condition at constant speed and side slip angle, where the geometric dihedral of an aeroplane is increased ?

Accepted Answer

Answer

The required lateral control force does not change.

Answer

The required lateral control force decreases.

Answer

The stick force per g decreases.
