Provision of robust flight control systems and structural mode stability margins and carefree handling in highly unstable combat aircraft with a wide range of store loading requires new methods for handling qualities optimization. The possibilities for new control modes and task-tailored handling were greatly enhanced by modern controls. This has led to development of many alternate criteria which were tried and tested in two digital fly by wire (FBW) research aircraft, the Experimental Aircraft Program (EAP) and Jaguar FBW, and were further developed for use in European fighter aircraft (EFA). They cover the field of flight path and attitude bandwidth, tracking dynamics and sensitivity, pilot-induced oscillation (PIO) prevention, and enhanced lateral directional damping. Derived as design guidelines with the facility to design for optimum rather than merely acceptable handling, more research is needed into formal boundaries for levels 1, 2, and 3 specifications. The criteria are reviewed and some are illustrated by example.
