The objectives of the Experimental Aircraft Programme were to demonstrate various technologies relevant to a future combat aircraft within the rigors imposed by having to achieve flight clearance and demonstration. Prime areas for demonstration, among others, were modern cockpit displays, avionics systems integration, advanced material construction, advanced aerodynamics and active flight control. Nearly all future combat aircraft will have an unstable basic airframe due to the advantages that are accrued: smaller, lighter, aerodynamically more efficient, etc. Necessary to such an aircraft is a full time active control system. This paper outlines the philosophy and method taken to design the flight control laws and relates their development through the life of the programme. The experience gained from the three phase, 259 flight test programme is summarized. The success of the flight programme has provided a wealth of experience from the operation of the aircraft. In particular, and most impressive to the pilots, was the carefree handling capability; this was considered remarkable. A further success was the complete absence of pilot induced oscillation (PIO) tendency throughout the whole of the flight programme.
