16.4.1.4 Crossfill
Dual units may be interfaced to crossfill information between the two units.
This option will not be available unless dual units are configured.
When Crossfill is turned on with one GTN, it is automatically turned on in the
other GTN. Some items are always crossfilled regardless of the crossfill setting;
others are dependent on the crossfill setting.
The GTN can be can also be interfaced with the GNS 400W/500W units. The
GTN can automatically send the Active Flight Plan and active Direct-To course to
the GNS unit. The GTN User Waypoints can be manually sent to the GNS unit. The
GNS unit can manually send its User Waypoints to the GTN unit.
Waypoint names longer than six characters, or duplicates, sent from the GTN
unit to the GNS unit will replace some characters with a "+" sign, while leaving
significant characters to aid in identification (such as, USR003 becomes US+003).
NOTE: Upon crossfill being activated, the GTNs may take up to 10 seconds
to crossfill the flight plans. The pilot must verify the flight plan in each unit
prior to use. The GTN and GNS units must have databases with the same cycle.
