When the system is used for single engine propulsion or for emergency generator engine a back up engine
control module is to be provided in order to maintain the engine operation even in case a "single failure" occurs.
A failure occurring in the ECM shall cause an alarm in the manned control stations.
The lines / switches regarding starting interlocks ( eg. reduction gear engaged, turning gear engaged, propeller
pitch not zero position) are to be monitored to produce an alarm in case of cable interruption (wire break monitoring).
In this event starting interlock of the engine is to be maintained.
The lines / switches regarding the engine emergency stop is to be monitored in order to produce an alarm
in case of cable interruption (wire break monitoring). In this event the engine has not to stop.
Safety functions are to be independent from the ECM in single and dual configuration.
System block diagram including power supply arrangement are to be sent for approval for each installation.
All changes in software and hardware are to be recorded as long as the system is in use on board.
The records of all changes are to be forwarded to RINA for evaluation and approval.
Major changes in the software / firmware / hardware are to be approved before being installed on the
