Aircraft Flight Controls

The three axes of an airplane are the longitudinal, lateral, and vertical axes. Which of the following correctly matches each axis with its means of control?

• Longitudinal - Ailerons, Lateral - Elevator, Vertical - Rudder

• Longitudinal - Elevator, Lateral - Rudder, Vertical - Ailerons

• Longitudinal - Rudder, Lateral - Ailerons, Vertical - Elevator

• Longitudinal - Ailerons, Lateral - Rudder, Vertical - Elevator

Flaps and slats are both high-lift devices on an aircraft wing. Which of the following best describes the main difference between them?

• Flaps are located on the trailing edge and increase lift and drag, while slats are on the leading edge and delay stall.

• Flaps are on the leading edge and reduce drag, while slats are on the trailing edge and increase lift.

• Both flaps and slats are only used during cruise flight.

• Flaps and slats both decrease lift during landing.

Spoilers and air brakes are used to:

• Increase lift during flight

• Reduce drag and increase speed

• Reduce lift and increase drag to slow down the aircraft

• Control the direction of the aircraft

What is the primary source of lift in a conventional airplane?

• The wing is the primary source of lift in a conventional airplane.

• The engine is the primary source of lift in a conventional airplane.

• The tail is the primary source of lift in a conventional airplane.

• The landing gear is the primary source of lift in a conventional airplane.

Which part of the airplane is attached to the wing and helps control roll?

• Ailerons are attached to the wing and help control roll.

• Rudder is attached to the tail and helps control yaw.

• Elevator is attached to the tail and helps control pitch.

• Flaps are attached to the wing and help increase lift during takeoff and landing.

List the components of the tail (empennage) of a conventional airplane.

• The tail (empennage) consists of: Horizontal stabilizer with its attached elevators, and vertical stabilizer (vertical fin) with its attached rudder.

• The tail (empennage) consists of: Ailerons and flaps only.

• The tail (empennage) consists of: Propeller and landing gear.

• The tail (empennage) consists of: Cockpit and fuselage.

Which axis of an airplane is controlled by the aileron?

• The longitudinal (roll) axis is controlled by the aileron.

• The vertical (yaw) axis is controlled by the aileron.

• The lateral (pitch) axis is controlled by the aileron.

• The diagonal axis is controlled by the aileron.

The longitudinal (roll) axis runs from the tip of the nose to the tip of the tail of the plane.

• True

• False

What is the motion about the lateral (pitch) axis called?

• Yaw

• Pitch

• Roll

• Drag

Pitching movement in an airplane is caused by the _________?

• elevator

• rudder

• aileron

• flaps
