Electronics Take Charge

Digital controls are handling more engine control tasks on a wider range of aircraft.

Electronic controls are slowly transforming aircraft engines of all types, bringing improved fuel consumption, improved efficiency, and more power. As the functionality of control units for jet engines increases, digital management is also adding more capabilities for helicopters and small piston engines.

Full authority digital engine controls (FADEC) continue to leverage the advances in semiconductors and software to improve engine management. As microcontroller capabilities soar, engine controllers can handle functions beyond the engines themselves. For example, the Lockheed Martin F-35B's engine controller also manages the short takeoff/vertical landing system.
