MIL-DTL-9490 Revision D Notice 1 - Validation:1992

This specification establishes general performance, design, develop, and
quality assurance requirements for the flight control systems of manned piloted aircraft. Flight Control Systems (FCS) includes all components used to transmit flight control commands from the pilot or other sources to appropriate force and moment producers. Flight control commands may result in control of aircraft flight path, attitude, airspeed, aerodynamic configuration, ride, and structural modes. Among components included are the pilot¿s controls, dedicated displays and
logic switching, transducers, system dynamic and air data sensors, signal computation, test devices, transmission devices, actuators, and signal transmission lines dedicated to flight control- Excluded are aerodynamic surfaces, engines, helicopter rotors, fire control devices, crew displays and electronics not dedicated to flight control. The interfaces of flight control systems with related subsystems are defined.
