Where are the ailerons located on an aircraft, and what is their primary function?

The ailerons are located on the trailing edge of the wings of an aircraft, and their primary function is to control the aircraft's roll, which is a type of horizontal motion. When a pilot moves the control stick or yoke left or right, the ailerons move in opposite directions: one aileron rises while the other lowers. This differential movement creates a difference in lift between the two wings, allowing the aircraft to roll to the left or right.

Understanding the placement and functionality of ailerons is essential for grasping the basic aerodynamics of flight. They play a critical role in maneuverability, enabling the aircraft to bank into turns and maintain stability during flight.
