*
Flight deck effect EICAS message and level
*
Flight deck effect activity
*
Fault code for the FDE
*
Time and date the FDE occurred
*
One or more maintenance message summary groups.
FDE and Maintenance Message Activity
The activity of an FDE shows as one of these:
*
Active
*
Latched
*
Not Active.
An active FDE is an FDE that currently shows in the flight deck.
A latched FDE can only be a status message or a scheduled maintenance task. Scheduled maintenance tasks are discussed in other parts of this section.
A failure that caused a status message may impact dispatch and may be intermittent or detectable only under certain conditions. The PDS holds a status message to make sure you can see it on the ground. You must do something to clear a latched FDE.
An FDE is not active if it can not currently be seen on the flight deck.

The activity of a maintenance message also shows as one of these:
*
Active
*
Latched
*
Not Active.
A maintenance message is active if a system can continuously monitor for a fault condition, and the fault exists.
A maintenance message is latched for one of these reasons:
*
If a system detected a fault and is no longer using the related equipment as part of its operational function
*
To ensure correlation with an FDE
*
If a system can not always detect if the fault exists.
You must do something to clear a latched maintenance message.
A maintenance message is not active if a system can continuously monitor for a fault condition, and the fault does not exist.
