NOTE
Sensor and Control Data Sharing Requires
Consistent Software Versions
For complete data sharing between dual IFDs, both
units will need to have the same main software
version. If the IFDs have different software versions,
then the sensor and control data (e.g. weather,
traffic, fuel, volumes, keyboard convenience mode,
etc.) will not be shared between the IFDs.
So, in summary, to have full data sharing between dual panel-
mount IFDs, the following rules must be satisfied:

CrossSync must be turned on in both IFDs (this is a
maintenance mode setting)

Both IFDs must have the same SBAS antenna
configuration

Both IFDs must have the same navigation database cycle

Both IFDs must have the same software version

Both IFDs must have the same setting for whether RF
Legs are enabled
Independent Data (Dual IFD Operations)
The following list of data will never be shared between two IFDs
no matter how they are configured:

IFD page and tab selection

Map view, range, declutter, and overlay settings

Navigation Source selection

Com/Nav settings (e.g. 8.33 vs. 25 kHz spacing)
†

Navigation deviation data (therefore no navigation
miscompare alerts are provided)

Local CAS alerts

Datablock configuration

Electronic Checklists data and state
