(1)
Crossfill is inhibited with the use of a latching (ON) crossfill inhibit switch.
Crossfill is enabled by releasing (OFF) this switch. The location and number
of crossfill inhibit switches in a cockpit varies by installation. Usually a single
crossfill switch can be centrally located in a side-by-side cockpit within reach
of both pilots. If a single switch cannot be installed within reach of both pilots
(tandem cockpits or very wide cockpits), two switches can be installed to
function in parallel (either switch inhibits or enables crossfill on both the pilot
and co-pilot sides).
(2)
Pilot and co-pilot flight plans can become unsynchronized under the following
conditions:
Crossfill is inhibited, and pilot and co-pilot flight plans are separately
changed before crossfill is re-enabled.
Either the pilot or co-pilot side is restarted with an active flight plan on the
other side and crossfill enabled.

synchronization function is available, arms horizon synchronization

DESIG (INFO) (L3)
: Creates a user waypoint at the current aircraft
location. In addition, if pressed with an ND page operating in pan mode,
creates a user waypoint at the panning location. User waypoint at
current aircraft location is automatically named “OF###,” where ### is
the next available over-fly user waypoint number. User waypoint at
panning location is automatically named “PN###,” where ### is the
next available panning user waypoint number. When pressed and the
number of user waypoint count is more than 998, the

message appears.
