D
Heading Source Annunciations
-- The heading source for this
display is the same source that drives the on--side PFD. Cross--side
data is displayed in amber. When the pilot and copilot horizontal
situation indicator (HSI) heading sources are the same, they are
annunciated in amber as is the heading source on the MFD.
NOTE:
When the selected heading source has failed, the heading
source is annunciated as HDG 1/2.
D
Drift Bug
-- A magenta drift or actual track is shown on the map
display. It is supplied by the FMS. The position of the bug, relative
to the compass display, represents the actual track across the
ground. Once established, the position of the bug, relative to the
heading reference line on the desired course, represents the aircraft
drift angle.
D
Range Rings
-- Range rings are displayed to determine the position
of radar returns and active flight plan parameters. The range ring
boundary is the compass card arc and it displays the MFD controller
selected range. A mid--range ring is displayed and labeled with the
half--range distance. The half--range ring is changed to an arc when
a vertical profile is displayed.
NOTE:
When weather radar data is displayed, the radar controller
is used to control the range.
D
Aircraft Symbol
-- The white aircraft symbol is a visual cue to
aircraft position, relative to actual heading and selected heading.
D
FMS Lateral Deviation Digital Display
-- Lateral deviation is
shown as a combination digital display with L/R direction. It is
displayed centered above the systems display area.
NOTE:
When the TCAS or checklist window is active, lateral
deviation is not displayed.
D
Heading Select Bug
-- A heading bug is displayed on the compass
arc. Its position follows the pilot’s HSI heading bug. When the bug
is not in view, a cyan arrow is displayed to indicate the shortest
direction to the bug’s position.
D
Pilot Designator
-- Use the remote--mounted joystick and the MFD
menu, joystick submenu functions from the MFD bezel menu, to
change the position of the square map designator. Distance and
bearing location of the designator, relative to its reference point, is
shown above the system display area. When the designator is
parked in its home position (the aircraft symbol) it is not displayed,
When anchored at a waypoint, it has the same color as the waypoint.
The color of the designator distance/bearing readout matches the
designator.
