FMC Communications Page
General datalink status displays on the FMC COMM page. Page select prompts
display for each FMC page with access to datalink data.
The page line title displays UPLINK when an uplink message is pending and all
preprocessing is complete. Preprocessing of uplinks ensures necessary data is
available for display when the uplink message is selected. Examples of
preprocessing include:
• RTE ALTN, ALTN LIST, PERF, TAKEOFF and WIND uplinks are held
until route activation or modifications are complete
• subsequent uplinks of the same type are held until previous uplinks are
included or discarded by the flight crew
When both ALTN and ALTN LIST uplinks are pending, (2) displays to the right
of UPLINK in the line title.
The EICAS message •FMC displays whenever any UPLINK message is pending.
Displays the datalink system status.
