Flight controls

The primary flight controls are:

• ailerons, elevator, rudder, spoilers

• ailerons, elevator, rudder, trimmers

• trim tabs, elevator, rudder, spoilers

• ailerons, fuselage, rudder, spoilers

(a)   are primary flight controls that control the movement of the aircraft about the lateral axis (pitch)

(a)   are moveable airfoil surfaces that provide control in flight in all directions.

(a)   are primary flight controls that provide lateral roll control of the aircraft.

(a)   is the flight control surface that controls aircraft movement about the vertical or normal axis.

(a)   reduce the lift of the wing when they operate together (lift dumping) or operate on one wing only, usually together with the ailerons to bank.

What are trim controls?

• trim tabs, servo tabs, balance tabs, and spring tabs

• trim tabs, servo tabs, balance tabs, and trimmers

• trim tabs, servo tabs, balance tabs, and wing

• trim tabs, servo tabs, balance tabs, and elevator

Depending on their function at the time, the spoilers can have different names:

• roll spoilers, speed brakes, ailerons

• roll spoilers,ground brakes, flight spoilers

• roll spoilers, speed brakes, ground spoilers

• roll spoilers, speed brakes, trim tabs

What's the purpose of trim tabs?

• to controls aircraft movement about the vertical or normal axis

• to reduce the lift of the wing when they operate together (lift dumping) or work as roll spoilers when they operate on one wing only

• to control the movement of the aircraft about the lateral axis (pitch)

• to enable the pilot to trim out any unbalanced condition which may exist during flight, without exerting any pressure on the primary controls.

What are the secondary flight controls?

• trim controls, high lift devices, spoilers

• trim controls, high lift devices, ailerons

• trim controls, high lift devices, speed brakes and lift dump

• rudder, high lift devices, speed brakes and lift dump
