777 CMCS / ACARS Question
Hi guys,
Can anyone help out with a tech question I have regarding the T7?
From the training manual:
Am I right in thinking that it is the CMCS that handles all the error/fault messages sent to the displays (EICAS), and these are classed as FDEs?
Does it handle master warnings/cautions as well?
Many thanks,
Martin
Can anyone help out with a tech question I have regarding the T7?
From the training manual:
The central maintenance computing system (CMCS) does these things:
- Monitors airplane systems for faults
- Processes fault information
- Supplies maintenance messages.
The CMCS also monitors flight deck effect (FDE) activity. The CMCS matches, or correlates, applicable FDEs and maintenance messages.
Flight deck effects (FDEs) tell the flight and ground crews of conditions related to safe operation. The ground crew must find the cause of an FDE to find the corrective action.
Flight Deck Effects
The airplane systems monitor conditions related to loss of a system or function. If a condition exists that requires repair or deferral, the airplane system sends FDE data to the AIMS primary display system (PDS). The
PDS shows the FDE.
