What flight control surface is primarily used to control roll about the longitudinal axis?
Answer: Ailerons
Ailerons on the trailing edges of the wings move opposite to each other to bank the aircraft and control roll.
The rudder controls movement of the aircraft about which axis?
Answer: Vertical axis
The rudder controls yaw, which is rotation about the vertical axis.
Which of the four forces of flight acts opposite to thrust?
Answer: Drag
Drag is the aerodynamic resistance that opposes thrust as the aircraft moves through the air.
An aircraft's angle of attack is the angle between the chord line and the:
Answer: Relative wind
Angle of attack is measured between the wing's chord line and the relative wind.
What happens to lift when an aircraft exceeds its critical angle of attack?
Answer: The wing stalls and lift decreases
Beyond the critical angle of attack, airflow separates from the wing and the wing stalls, causing a loss of lift.
On a standard fixed-wing aircraft, the elevator is used to control:
Answer: Pitch
The elevator on the horizontal stabilizer controls pitch, moving the nose up or down about the lateral axis.
Bernoulli's principle helps explain lift by relating increased airflow speed over the wing to:
Answer: Lower pressure
Faster airflow over the curved upper surface produces lower pressure, contributing to lift.
