Definition

The term electronic engine control (EEC), in commercial air transport aeroplanes and other aircraft (e.g., turbine-powered helicopters), can refer to:

• an early-generation computer system designed for fuel-flow regulation of an engine, thrust management of an engine and interface with flight crew–alert systems throughout normal flight operations, while allowing manual overrides/interventions by the pilot; or,
• a descriptive category for such computer systems covering early EEC units and later-generation designs, such as full authority digital engine control (FADEC) systems, which are not designed for intervention by the pilot.

A synonym within the aviation industry is engine control unit (ECU).
