Section 41
Introduction
The NDs provide a mode-selectable color flight progress display. The modes are:
• MAP
• APP (approach)
• VOR
• PLN (plan).
The MAP, VOR, and APP modes can be switched between an expanded mode
with a partial compass rose and a centered mode with a full compass rose.
Map Mode
The MAP mode is recommended for most phases of flight.
[Option - Track-up display]
Presented track up, this mode shows airplane position relative to the route of flight
against a moving map background.
Displayed information can include:
• current track
• true airspeed
• selected and current heading
• wind direction and speed
• position trend vector
• next waypoint distance
• range to selected altitude
• waypoint estimated
• map range scale
time of arrival
• ground speed
• selected navigation data points.
Navigation Data Points
Additional navigation facility (STA), waypoint (WPT), airport (ARPT), route
progress (DATA) and position (POS) data are available for display on the ND in
both the expanded and center map modes.
VOR and Approach Modes
The VOR and APP modes are presented heading up. The VOR and APP modes
display track, heading, and wind speed and direction with VOR navigation or ILS
approach information.
Plan Mode
The PLN mode is presented true north up. The active route may be viewed using
the STEP prompt on the CDU LEGS pages.

Boeing 737 Operations Manual
ND Information
Heading
Heading is supplied by the FMC or air data inertial reference system (ADIRS).
The ND compass rose can be referenced to magnetic north or true north.
Track
Track is supplied by the FMC during normal operation.
Traffic
Traffic information from the TCAS can be displayed on the ND. TCAS is
described in Chapter 15, Warning Systems.
Weather Radar
Weather radar information can be displayed on the ND. The weather radar system
is described in Chapter 11, Flight Management, Navigation.
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
ND exceeds the display capability. When this occurs, the primary display system
removes information from the outer edge of the display. The message can be
removed by:
• reducing the amount of map information
• reducing range, or
• deselecting one or more of the EFIS control panel map switches (STA,
WPT, ARPT, DATA, POS).
ND Symbology
The following symbols can be displayed on each ND, depending on EFIS control
panel switch selections. Colors indicate the following:
• W (white) - present status, range scales
• G (green) - dynamic conditions
• M (magenta) - command information, pointers, symbols, fly-to condition
• C (cyan) - nonactive or background information
• A (amber) - cautions, faults, flags
• R (red) - warnings
• B (black) - blank area, off condition.
