What are the two primary types of flight controls on the F/A-18 E/F?

The two primary types of flight controls on the F/A-18 E/F are classified as primary and secondary flight controls. Primary flight controls, which include the ailerons, elevators, and rudder, are essential for the basic maneuvers of the aircraft, allowing pilots to manage pitch, roll, and yaw during flight. These controls are crucial for maintaining stability and executing standard flying operations.

On the other hand, secondary flight controls, which consist of devices like flaps, slats, and speed brakes, assist in enhancing the performance of the aircraft but are not critical for basic maneuverability. They help in improving lift and drag characteristics, thereby facilitating better performance during takeoff, landing, and certain flight conditions.

This categorization into primary and secondary highlights the structure of flight control systems in the F/A-18 E/F, emphasizing how different elements work together to ensure safe and effective aircraft operation.
