ACT System Design for Reliability, Maintainability and Redundancy Management

The specifications of design requirements for Active Control Technology (ACT) flight control systems are addressed based on current state-of-the-art trends with emphasis placed on the impact of specific requirements on system mechanization. Of particular interest is the sensitivity of the ACT system design to redundancy managment, reliability and maintainability requirements, and to the related subsystem interface concepts. Experience on both military and commercial aircraft programs is cited to provide insight to establishment of practical design requirements for ACT systems.
