10.40 Flight Instruments, Displays-Navigation Displays Introduction
The NDs provide a mode–selectable color flight progress display. The modes are:
The MAP mode can be switched between an expanded mode with a partial
compass rose and a centered mode with a full compass rose. Both MAP and PLAN
modes can be shown in Normal and Full-display format. Refer to the System
Description section of this chapter for more information on display management.
Map Mode
The MAP mode is recommended for most phases of flight.
Presented track up, this mode shows airplane position relative to the route of flight
against a moving map background.
Displayed information can include:
Navigation Data Points
Additional navigation facility (STA), waypoint (WPT), airport (APT), route
progress (DATA) and position (POS) data are available for display on the ND in
both the expanded and center map modes.
Plan Mode
The PLAN mode is presented true north up. The active route may be viewed using
the STEP prompt on the CDU LEGS pages.
• MAP • PLAN.
• selected and current track
• selected and current heading
• position trend vector
• range to selected altitude
• map range scale
• ground speed

ND Information
Heading
Heading is supplied by the FMC or inertial reference system (IRS). The ND
compass rose can be referenced to magnetic north or true north. The heading
reference switch is used to manually select magnetic or true reference. The
compass display is automatically referenced to true north when the airplane is
north of 82° north or south of 82° south latitude, or near the magnetic poles with
the heading reference switch in NORM.
Track
Track is supplied by the FMC during normal operation and by the Tuning and
Control Panel (TCP) when in alternate navigation.
Traffic
Traffic information from the TCAS can be displayed on the ND and the
Mini-MAP. TCAS is described in Chapter 15, Warning Systems.
Weather Radar
Weather radar information can be displayed on the ND and Mini-MAP. The
weather radar system is described in Chapter 11, Flight Management, Navigation.
Airport Map
The Airport Map is integrated with the ND as an underlay and consists of
runways, taxiways, aprons and buildings with the appropriate labels. The FMC
provides the position of the airplane. The Airport Map is automatically displayed
when the following conditions are met:
• the airport is either the ORIGIN or DESTINATION airport as specified in
the active flight plan
• the airport is in the Airport Map database
• the ND range is 5NM or less.
The Airport Map can be displayed in either a track-up mode (MAP) or north-up
mode (PLAN). The Airport Map may be displayed at 5NM, 2NM, 1NM and
0.5NM by selecting the range on the EFIS Control Panel.
Vertical Situation Display (VSD)
The VSD presents a profile view of the airplane and its environment. Information
shown within the cyan dashed lines (enroute corridor) on the ND is shown in
profile on the VSD. The pilot selects the VSD display from the map information
selections on the MAP mode pull-down menu.

The VSD depicts terrain and waypoint information that is within the cyan swath
on the ND. The VSD range is a function of the ND range and is depicted on the
horizontal reference scale. The normal-display VSD has the same range as the ND
except when the ND range is less than 5 NM. The full-display VSD has twice the
range of the ND, ranging from 10 NM to 2560 NM.
The altitude reference scale is linked to the VSD range and is not independently
adjustable. This ensures that a consistent 3 degree glidepath is depicted. The
altitude shown on the VSD is the same as the altitude shown on the on-side PFD.
Failure Flags and Messages
Failure flags are displayed for system failures or invalid information. Indications
are removed or replaced by dashes when source system information is not
available.
The message EXCESS DATA is displayed if the amount of information sent to the
