AFOQT Aviation Information Concepts 2

Question 1

What flight control surface is primarily used to control roll about the longitudinal axis?

Accepted Answer

Ailerons

Answer

Ailerons on the trailing edges of the wings move opposite to each other to bank the aircraft and control roll.

Question 2

The rudder controls movement of the aircraft about which axis?

Accepted Answer

Vertical axis

Answer

The rudder controls yaw, which is rotation about the vertical axis.

Question 3

Which of the four forces of flight acts opposite to thrust?

Accepted Answer

Drag

Answer

Drag is the aerodynamic resistance that opposes thrust as the aircraft moves through the air.

Question 4

An aircraft's angle of attack is the angle between the chord line and the:

Accepted Answer

Relative wind

Answer

Angle of attack is measured between the wing's chord line and the relative wind.

Question 5

What happens to lift when an aircraft exceeds its critical angle of attack?

Accepted Answer

The wing stalls and lift decreases

Answer

Beyond the critical angle of attack, airflow separates from the wing and the wing stalls, causing a loss of lift.
