FULL AUTHORITY DIGITAL ENGINE CONTROL (FADEC)

A dual-channel, fully redundant system with the latest technological innovations, currently in certification

• Dual ignition and dual injection
• Single-lever control for significantly decreased pilot's workload
• Easy, dependable starts
• Optimised engine settings in all flight phases
• Reduced operating and maintenance costs
• Increased overall operational safety

Mistral's FADEC system controls the electronic fuel injection and ignition systems, as well as the exhaust wastegate on turbocharged models. Its control algorithms are based on a single lever controlling engine power and on measurements of critical engine parameters such as engine speed and shaft angle, manifold pressure and temperature, etc. A broad-band oxygen sensor ensures that the engine is always running with the optimum mixture and compensates for different fuel qualities. Single-lever control reduces pilot workload and increases safety by allowing you to concentrate on more critical aspects of flight.

The system consists of two independent engine control units. Each ECU is also constantly supervising the other. The two ECUs, as well as the pilot display and interface module, communicate via a CAN bus. In the unlikely event of a partial or complete failure of one of the ECUs, the other unit assumes full engine control and monitoring, and informs the pilot of the failure via both an alarm LED and a plain-English message on the display. (A voice-generator option can also transmit the alert message on the aircraft audio system). In the event of an ECU failure, the maximum power is reduced to a level similar to a conventional engine operating on a single magneto.
