Flight Controls Quiz

What is one purpose of wing flaps?

• To enable the pilot to make steeper approaches to a landing without increasing the airspeed.

• To relieve the pilot of maintaining continuous pressure on the controls.

• To decrease wing area to vary the lift.

One of the main functions of flaps during approach and landing is to

• decrease the angle of descent without increasing the airspeed.

• permit a touchdown at a higher indicated airspeed.

• increase the angle of descent without increasing the airspeed.

What is the purpose of the rudder on an airplane?

• To control yaw.

• To control overbanking tendency.

• To control roll.

Which is not a primary flight control surface?

• Flaps.

• Stabilator.

• Ailerons.

The elevator controls movement around which axis?

• Longitudinal.

• Lateral.

• Vertical.

Which of the following is true concerning flaps?

• Flaps are attached to the leading edge of the wing and are used to increase wing lift.

• Flaps allow an increase in the angle of descent without increasing airspeed.

• Flaps are high drag devices deployed from the wings to reduce lift.

Which device is a secondary flight control?

• Spoilers.

• Ailerons.

• Stabilators.

Trim systems are designed to do what?

• They relieve the pilot of the need to maintain constant pressure on the flight controls.

• They are used during approach and landing to increase wing lift.

• They move in the opposite direction from one another to control roll.

Which statement is true concerning primary flight controls?

• The effectiveness of each control surface increases with speed because there is more airflow over them.

• Only when all three primary flight controls move in sequence do the airflow and pressure distribution change over and around the airfoil.

• Primary flight controls include ailerons, rudder, elevator, and trim systems.
