Electric power in modern aircraft is becoming more and more important not only for powering essential systems but also to keep the aircraft in control. Stability Augmentation Systems in fly-by-wire aircraft cannot tolerate power interruptions as loss of power would cause loss of control of the aircraft itself. This paper describes the needs of the avionics and flight control systems in terms of quantity and quality of electric power required. Special requirements such as uninterruptible electric power and ultra-high reliability will be defined. These requirements will have to be met by incorporation of special features in the power generation and distribution systems, the control and protection and the utilization systems. It is significantly easier to provide uninterruptibility in dc-powered equipment.
