What is the primary group of flight control surfaces composed of?

The primary group of flight control surfaces consists of ailerons, elevators, and rudder. These surfaces are essential for managing the aircraft's attitude and direction during flight.

Ailerons are located on the outer portions of the wings and control roll, allowing the aircraft to turn left or right. Elevators are found on the horizontal stabilizer and manage pitch, which is the angle of the nose in relation to the horizon. The rudder, positioned on the vertical stabilizer, controls yaw, allowing the aircraft to move left or right around its vertical axis.

Together, these control surfaces form the core of an aircraft's control system, providing the pilot with the ability to maneuver effectively and maintain stability during flight. This set is fundamental for basic flight dynamics, distinguishing it from secondary or auxiliary control surfaces, which serve other specialized functions like enhancing lift or drag.
