Abstract:
This paper briefly describes the digital Integrated Flight Control System IFCS developed for the Jaguar Fly-By-Wire FBW demonstrator programme, identifying the specification requirements, resultant architecture, implementation and the incorporated self test capability. The redundancy management aspects of the IFCS are described together with the techniques for providing the pilot with relevant information to determine the IFCS redundancy status. Particular emphasis is given to the software definition and preparation procedures, and the comprehensive integrity appraisal leading to flight clearance of the system. The reliability of the aircraft and IFCS have proved, to date, to be excellent. Thus practical in-flight results of the systems ability to absorb and survive fault conditions are minimal. The redundancy management and integrity experience provided by the programme has therefore principally been in the theoretical analysis supported by the controlled experimentation on the rig. These exercises have highlighted key areas of the system and software design techniques which enable these aspects to be fully and economically evaluated. These areas are described, with mention of how these techniques are being developed to simplify and improve the exercise for future high integrity digital flight control systems.
