NOTE
FADEC engine protections are fully independent of AT engine protections.
When FADEC engine protection is active, the engine power may be limited and
ENG PROT ACTIVE
is displayed in the CAS window.
The activation of protections may also lead to the loss of functions associated with
CAS messages displayed in the CAS window.
FADEC System Faults Indications
The FADEC continuously monitors the integrity of its inputs, internal hardware
functions and external driver circuits.
When an input fault is detected, the FADEC selects an alternative valid input.
When an output fault is detected that prevents the channel in control from
controlling the engine or propeller, the FADEC transfers control to the other
channel in order to maintain engine operability.
Multiple faults are accommodated by alternative input sources, backup control
loops and by always choosing the best channel to control the engine. Each
channel is responsible for the detection and accommodation of its own failures
and for transferring control to the other channel.
All detected faults are sent to the avionics, recorded on the DCTU and monitored
through associated CAS messages triggered during ground and flight operations.
CAS message
Description
FADEC FAULT
Indicates that the FADEC system is in degraded
mode without effect on engine operation.
The control system has experienced a FADEC
system componant fault that has been automatically
accommodated to provide continued operation
without operational impact.
