Chapter One - Airplane Aerodynamics

Question 0

One of the main functions of flaps during approach and landing is too?

Answer 0

Increase the angle of the descent without increasing the airspeed.

Question 1

What is one purpose of wing flaps?

Answer 1

Extending the flaps increases the wing camber and the angle of attack of the wing. This increases wing lift and induced drag, which allows the pilot to make steeper approaches to a landing without increasing airspeed.

Question 2

What is the purpose of the rudder on an airplane?

Answer 2

The rudder controls yaw.

Question 3

What is not a primary flight surface?
A. Flaps
B. Stabilator
C. Ailerons

Answer 3

A. Flaps are not a primary flight surface.

Question 4

The elevator controls movement around which axis?

Answer 4

The elevator controls pitch on the lateral axis.

Question 5

Which of the following is true concerning primary flight controls?
A. The effectiveness of each control surface increases with speed because there is more flow over them.
B. Only when all three primary flight controls move in sequence do the airflow in pressure distribution change over and around the airfoil.
C. Primary flight controls include ailerons, rudder, elevator, and trim systems.

Answer 5

A. Effectiveness increases with speed because of additional flow.

Question 6

Which device is a secondary flight control?
A. Spoilers
B. Ailerons
C. Stabilator

Answer 6

A. Spoilers.

Question 7

Trim systems are designed to do what?

Answer 7

They relieve the back pressure on the flight controls.

Question 8

What forces make an airplane turn?

Answer 8

The horizontal component of lift.
