Development of autonomy in fly-by-wire aircraft has long been limited to multi-million dollar systems, or large remotely operated vehicles due to regulatory restrictions and the difficulty of designing a system around existing light aircraft. This report summarises the development of an experimental, optionally piloted aircraft with the capability of fully autonomous decision making and controlled flight. Particular time is spent discussing the safety features of the mechanical and electrical systems, as well as a novel control system design for light aircraft autopilots. This phase of the project included independant ground tests of all electromechanical systems, and simulator tests of all autoflight software. The next phase of the project will include flight testing
