How the term is used
FADEC uses sensors, control computers and actuators to schedule fuel and other engine functions while protecting limits and providing monitoring and fault information. Architecture and redundancy vary by engine.
Where you may encounter it
Technicians use approved tests, wiring data and engine documentation when diagnosing control-system faults.
Do not infer component failure from a single message. Power supply, inputs, wiring and system logic must be considered.
