Full Authority Digital Engine Control
Aerospace Engineering · Last updated: July 30, 2026 · How this entry was written
Definition: A digital electronic system that manages all aspects of aircraft engine performance, including fuel flow, thrust, and start-up sequence, without pilot intervention. It replaces mechanical controls and optimizes efficiency and safety.
Example in context
“The FADEC system automatically adjusts fuel flow based on altitude and ambient temperature to maintain optimal engine performance.”
“FADEC sistemi, optimum motor performansını korumak için yüksekliğe ve ortam sıcaklığına göre yakıt akışını otomatik olarak ayarlar.”
Where engineers use it
FADEC is used in modern aircraft like the Boeing 787 and Airbus A350 for engine control. Engineers refer to FADEC during maintenance to diagnose sensor faults and during flight test to verify thrust response.
Synonyms: FADEC
Antonyms: hydromechanical engine control
Practice: can you use “Full Authority Digital Engine Control” at work?
A trainee engineer is troubleshooting a transient overboost condition on a turbofan engine. They must explain how FADEC's feedback loops prevent such events.
