The control system of the National Aerospace Laboratory Quiet-STOL Research Aircraft has a mechanical control system and a triplex digital Stability and Control Augmentation System (SCAS). The mechanical system is responsible for the safety control system, while the digital SCAS system was to be evaluated through experiments. Functional mock-up tests were carried out to check safety and performance of the total control system using actual system component hardware and simulating aerodynamic and mechanical environmental conditions. The mechanical system dynamics test and the total plan for the functional mock-up test are described as the fundamental process to ensure minimum safety requirements of the system component matching. The static and dynamic characteristics of the mechanical control system showed good agreement with the specifications of Japanese Airworthiness Standards (equivalent to FAR25) and MIL.
