SU-1 Airplanes and Aerodynamics PP Exam

Front

What is one purpose of wing flaps?

Back

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

Front

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

Back

increase the angle of descent without increasing the airspeed.

Front

What is the purpose of the rudder on an airplane?

Back

To control yaw.

Front

Which is not a primary flight control surface? Options: Flaps, Stabilator, Ailerons

Back

Flaps

Front

The elevator controls movement around which axis? Longitudinal, Lateral, Vertical

Back

Lateral

Front

Which statement is true concerning primary flight controls? Options: 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.

Back

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

Front

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 wing to reduce lift.

Back

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

Front

Which device is a secondary flight control? Options: Spoilers, Ailerons, Stabilators

Back

Spoilers

Front

Trim systems are designed to do what?

Back

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

Front

The four forces acting on an airplane in flight are: lift, weight, thrust, and drag.

Back

lift, weight, thrust, and drag.
