Cessna 172 Systems Practice Test 2025 – 400 Free Practice Questions to Pass the Exam

The ailerons on a Cessna 172 primarily function to control the roll of the aircraft during flight. Located on the outer trailing edges of both wings, they work opposite each other, with one aileron deflecting upward while the other deflects downward. This differential movement creates a difference in lift between the wings, causing the aircraft to roll to the left or right around its longitudinal axis.

This roll control is essential for maneuvering the aircraft during flight, allowing the pilot to execute turns and maintain balance in various flight conditions. Understanding the ailerons' role in controlling roll is crucial for safe and effective flight operations. The other functions mentioned, such as controlling pitch or yaw and managing landing gear, are accomplished by other flight control surfaces or systems within the aircraft, highlighting the specialized nature of the ailerons in roll control.
