How many channels are included in the FADEC system?

The FADEC (Full Authority Digital Engine Control) system is designed to manage the performance of aircraft engines effectively and reliably. Typically, the FADEC system includes two channels to ensure redundancy and enhance safety. Each channel operates independently, allowing for the continuous monitoring and control of the engine's functions. If one channel fails, the other can take over, ensuring that engine control remains operational without affecting safety or performance. This dual-channel architecture is crucial in critical systems like engine control, where reliability is paramount. By having two channels, the FADEC system can also perform cross-checks between the channels to maintain accuracy and operational integrity, making it a robust solution for managing engine parameters under varying conditions.
