What is the primary role of the ailerons on an aircraft?

• A. Control pitch
• B. Control roll
• C. Control yaw
• D. Increase drag

Answer: (B)

The primary role of the ailerons on an aircraft is to control roll. Ailerons are located on the trailing edge of each wing and they move in opposite directions. When one aileron is deflected upward, the other is deflected downward. This creates a difference in lift between the two wings, which causes the aircraft to rotate around its longitudinal axis. This motion is essential for banked turns and maintaining level flight when encountering turbulence. By enabling the pilot to control the roll of the aircraft, ailerons play a crucial role in maneuverability and stability during flight. Understanding the function of ailerons is fundamental for comprehending how pilots control an aircraft's orientation in the air.
