identification of the tuned navaid or next waypoint displays with the distance to that
position (in nautical miles). The NAV source is boxed and red if the NAV data is
invalid.
• Cross-side Course Display: The (right) display window shows cross-side course
information in cyan. This information is the active NAV course data displayed on
the cross-side PFD. A dual dashed-line course cyan pointer also indicates crossside
course
Cross-side course information is selected or deselected for
display by the PUSH X-SIDE switch on the DCP.
Compass Rose
The compass rose contains index markings every five degrees and alphabetic or
numeric markings displayed at 30-degree intervals. Additional fixed index marks
display outside the compass rose perimeter at 45-degree intervals with respect to the
lubber line.

Airplane Symbol
A stationary airplane symbol displays in the center of the compass rose. This symbol
points directly toward the lubber line.
Lubber Line
The lubber line is a fixed symbol at the top of the compass rose. The current airplane
heading is the compass reading directly under the lubber line.
Selected Heading Bug
A heading bug symbol marks a selected heading reference. Turn the HDG knob on the
FCP to move the heading bug around the compass rose. Momentarily pushing the
center switch (PUSH SYNC) of the knob resets the heading bug to the current airplane
heading.
Selected Heading Display
This display numerically shows the position of the selected heading bug. This display
appears when the HDG knob is turned and disappears three seconds after rotation
stops.
Drift Angle Pointer
This pointer is a small green circle that shows the airplane drift angle.
Bearing Pointers
There are two bearing pointers that may be selected for display (BRG buttons on
DCP). One pointer is a single bar and the other pointer is a dual bar. Each pointer
shows the bearing to a selected navaid station or the next FMS waypoint. The
appropriate source for the bearing pointer is displayed below it.
Course Pointers
The on-side course pointer is a solid-line pointer. This pointer shows the on-side NAV
course. This value is numerically repeated in the on-side course display. Push the DCP
X-SIDE button to display the cross-side cyan course pointer.
The cross-side course pointer is a dual dashed-line cyan pointer. This pointer shows
the cross-side NAV course. This value is numerically repeated in the cross-side course
display.
To/From Symbol
A triangle symbol shows “to” or “from” direction. This symbol turns as a part of the
on-side course pointer and points toward the tuned station or next waypoint.

Lateral Deviation Bars
The lateral deviation bars are the center portions of the course pointers. Each bar
moves left or right from the pointer to show lateral deviation from the NAV course.
Lateral Deviation Scale
The lateral deviation scale consists of four dots that display perpendicular to the onside
course lateral deviation bar. Two dots display on either side of the airplane
symbol.
Vertical Deviation Display
The ILS glideslope or the FMS VNAV vertical deviation display appears when all
appropriate conditions are met. The on-side DCP selects LOC/FMS as the active NAV
source. If, or as deviation data becomes invalid, this display is replaced with a red GS
icon. When FMS VNAV deviation data is invalid, the deviation scale and pointer are
removed. When making a back course approach, the scale displays without a pointer
or flag annunciation.
ILS/GS vertical deviation is shown by the position of a green diamond-shaped pointer
relative to the deviation scale; whereas a white star pointer shows the FMS VNAV
vertical deviation. The scale consists of two dots above and two dots below center. If
GS deviation becomes excessive, the pointer and scale flash yellow.
