FMCS - OFP CROSSLOAD PAGE General
The OFP CROSSLOAD page lets you review and, if necessary, transfer the operational flight program (OFP) between the primary and secondary FMCs.
Page Access
This page shows for any of these conditions:
-If, during ground power-up, the primary FMC finds a mismatch
between its valid OFP and that of the secondary FMC -An OFP with a different update version is loaded into one FMC -Selection of the CROSSLOAD prompt on the FMCS BITE INDEX
page if there is an OFP mismatch currently.
If there is no mismatch between the OFPs but there is an analog discrete mismatch, the ANALOG DISCRETE page shows with the specific mismatch highlighted.
OFP Crossload Page Information
Line select key 1L and 1R show the OFP software part numbers for the left and right FMCs if there is an OFP mismatch. If there is no mismatch these data fields are blank.

-CROSSLOAD COMPLETE -CROSSLOAD FAIL (the data base in the source FMC did not crossload to the target FMC) -CROSSLOAD UNAVAILABLE (the source FMC can not interface with the other FMC) -SET FMC SOURCE SELECT TO BOTH ON R (shows when the primary FMC is also the target FMC).
To start the crossload, select COPY FROM LEFT or COPY FROM RIGHT on the MCDU and push the EXEC key. The message CROSSLOAD IN PROGRESS shows during the crossload process. At the end of the crossload, the message CROSSLOAD COMPLETE shows on the MCDU.
Line select key 6L shows one of these prompts:
-INDEX (selects the FMCS BITE INDEX page) -CANCEL (shows when the source FMC for the crossload has been selected but the EXEC key has not been pressed) -NEXT MISMATCH.
The NEXT MISMATCH prompt shows either the specified ANALOG DISCRETE page if there is a discrete mismatch currently or the DATABASE CROSSLOAD page if there is not a discrete mismatch but there is a data base mismatch.
If there are no more mismatches between the FMCs, the INDEX prompt shows.
This line is blank while the crossload is in progress.
