SAE ARP5764

The purpose of this document is to develop the general characteristics and requirements for feel-force control systems for active cockpit controllers, also known as Active Inceptors. The document presents technical material that describes the recommended key characteristics and design considerations for these types of systems. Where appropriate, the effects of platform specific requirements (e.g., single axis/dual axis, single seat/dual seat, civil/military, rotorcraft/fixed wing aircraft, etc.) are clearly identified. The material developed will serve as a reference guide for: a Aircraft prime contractors who want to understand active cockpit controller technology and develop their own set of requirements; b Suppliers that develop active cockpit controller equipment and; c Regulatory Authorities who will be involved in the certification of these types of systems. Active Inceptor Systems are a class of pilot cockpit controllers that include a programmable servo actuator controlled feelforce system, and are being developed and flight tested for both fixed and rotary wing aircraft, some of which are entering service. This Aerospace Recommended Practice fulfills the need for a document which defines the general characteristics and requirements for these feel-force control systems.
