DATA BASE LOADING
CROSSLOADING DESCRIPTION
The crossloading allows an FMGC to transfer its valid
navigation data base to the other FMGC through the
crosstalk busses by simple MCDU selection.
The objective of the crossloading is:
- to reduce loading time for periodic updating
of navigation data base.
- to avoid the use of a portable data loader in
case of replacement of an FMGC.
The crossloading is initiated from either MCDU 1 or
MCDU 2 (depending on which FMGC contains the valid
navigation data base), via the ACTIVATE CROSSLOAD
prompt on the AIRCRAFT STATUS page.
The ACTIVATE CROSSLOAD prompt is displayed when the
following is true:
- the active flight phase is either PREFLIGHT or
DONE,
- the FMGCs work in independent operation,
meaning that the navigation data base
loaded in one FMGC is different from the
other one.

DATA BASE LOADING
CROSSLOADING OPERATION
Pressing the line select key associated to the ACTIVATE
CROSSLOAD prompt identifies the transmitting FMGC.
In this example, the transmitting FMGC is FMGC 1.
The CONFIRM CROSSLOAD prompt is displayed on the
AIRCRAFT STATUS page of MCDU 1 and the AIRCRAFT STATUS
PAGE of MCDU 2 is blanked.
As soon as the CONFIRM CROSSLOAD prompt is selected,
the crossloading begins.
While crossload is in process, the current percentage
of crossload completion is displayed on both MCDUs.
Upon successful completion of the crossload, both MCDUs
revert to the AIRCRAFT STATUS page.
The CROSSLOAD COMPLETE message is displayed in the
scratchpad of each MCDU.

CROSSLOADING OPERATION (CONTINUED)
The crossload may be unsuccessful.
The CROSSLOAD ABORTED message is then displayed in the
scratchpad of each MCDU and the NAV DATA BASE LOAD
INCOMPLETE message is displayed on the MCDU associated
to the receiving FMGC (In this example, MCDU 2).
This may occur:
- if flight phase transitions from PREFLIGHT or
DONE to another phase occur while crossload is
in process,
- following a failed or incomplete data base
loading operation.
