Answer to Question #138869 in English for mari

Question

● Decide whether the following statements are correct (✔)OR incorrect (x). Try to correct the false ones:

1.The empennage usually includes the fin, rudder, horizontal stabiliser ( or tailpane) and elevator.
2. The rudder rotates the aircraft about its horizontal axis to produce yaw.
3. The aileron is a horizontal control surface, hinged to the mainplane, which enables the aircraft to pitch.
4. In order for the aircraft to increase speed, thrust must be equal to drag

Answer 1

T/F Questions

Question One

The statement is correct.

Question Two

The statement is correct

Question Three

The statement is incorrect because the elevators are the primary control surfaces for pitch. On the other hand, the aileron's control surface controls the movement about an aircraft's longitudinal axis. They, therefore, control the movement referred to as Roll.

Question Four

The statement is incorrect.

Thrust is the forward force that is produced to overcome drag forces. Drag force is the force that exerts braking action to slow the airplane. Thus, for an airplane to speed up, thrust force must be greater than the drag force.
