D Navigation Source Annunciator -- This annunciator indicates the
source of the course and deviation information selected with the
NAV source buttons on the display controller. The annunciator is
VOR 1/VOR 2, LOC 1/LOC 2, or FMS 1/FMS 2. A green
annunciator indicates on--side NAV source selection and yellow
indicates cross--side NAV source selection.
The BC annunciator is displayed in place of the LOC 1/LOC 2
annunciator when difference between the selected course and
aircraft heading is more than 100 and LOC 1 or LOC 2 is the
displayed NAV source.
D Waypoint/DME Identifier -- The identifier is displayed, if valid, for
the FMS waypoint or the DME station that is associated with the
distance display in the upper right corner of the EADI. For FMS only,
a lateral waypoint crossover is identified by a flashing waypoint
identifier.
NOTE: This information is from the selected FMS navigation
database.
D Distance Display -- The distance display indicates the nautical
miles (NM) to the selected DME station or FMS waypoint. When
DME is annunciated, the display range is 0 to 399 NM. The DME
display digits are replaced by dashes in the search phase. DME hold
is annunciated by an H adjacent to the distance readout. When FMS
is annunciated, the display range is 0 to 3999 NM. For both DME and
FMS, the display resolution is 0.1 NM from 0 to 99.9 NM and 1 NM
from 100 to 3999 NM. If distance is not available or invalid, the DME
or the FMS annunciator remains displayed, but the digital readout
is removed.
D FMS Approach (APP) Annunciator -- The FMS APP annunciator
is located to the right of the distance display. It is triggered by the
FMS.
— FMS prior to NZ--4.1 Software -- The annunciator is shown when
the aircraft is within 10 NM of the destination along the flight path.
— FMS NZ--4.1 and Later Software -- The annunciator is shown
when FMS approach conditions are met and the aircraft is 2 NM
outside the final approach fix.
