Question

Which of the following is not a secondary control?

(a) Slats

(b) Ailerons

(c) Spoilers

(d) Air brakes

The question was posed to me in class test.

I need to ask this question from Flight Control-1 topic in section Flight Dynamics and Control of Aircraft Maintenance

Answer 1

The correct option is (b) Ailerons

To explain I would say: The ailerons are part of the primary cockpit flight controls. The roll and pitch of the aircraft can be adjusted using the ailerons. Slats, spoilers and air brakes are part of the secondary flight controls.
