What do secondary control systems in aircraft primarily do?

Secondary control systems in aircraft are primarily designed to improve performance. These systems complement the primary flight controls by providing additional capabilities that enhance the overall efficiency and effectiveness of the aircraft during various flight operations. They can include systems such as flaps, slats, ailerons, and other aerodynamic devices that help optimize lift and drag characteristics at different speeds and phases of flight.

While secondary control systems certainly contribute to safety features and can indirectly affect pitch control and airspeed measurements, their main function is to augment the aircraft's performance. By allowing pilots to fine-tune the aircraft's response to control inputs, adjust lift during takeoff and landing, and maintain control in various flight conditions, these systems play a critical role in enhancing the aircraft's operability and efficiency.
