Approach Minimums
[Option - Radio altitude above ADI]
The selected radio altitude or barometric approach minimums are set on the EFIS
control panel. The radio altitude approach minimum is displayed near the top left
of the altitude display and the barometric approach minimums is displayed near
the bottom left of the altitude display.
Radio Altitude
[Option - Radio altitude above ADI, round dial]
The current radio altitude is displayed above the upper right corner of the attitude
indication area when radio altitude is below 2,500 feet AGL. When between 1000
feet and 2500 feet AGL, the readout is digital. When below 1000 feet AGL, the
readout is displayed in a round dial format. The display turns amber when the
radio altimeter is below the radio altitude minimums.
Altitude
Altitude is displayed on an altitude tape along the right side of the PFD. It is also
shown digitally in a window in the middle of the tape. When meters is selected on
the EFIS control panel:
• current altitude in meters is also shown above the altitude window
• selected altitude in meters is displayed above the altitude tape.
Selected altitude is displayed above the altitude tape and is boxed when
approaching the selected altitude. Selected altitude is also depicted with a bug on
the altitude tape.
[Option - Landing altitude reference bar]
A landing altitude reference bar is displayed along the inner edge of the altitude
indication. The reference bar indicates the height above touchdown. A white bar
is displayed from 1000 to 500 feet above landing altitude. An amber bar is
displayed from 500 feet to the landing altitude.
A landing altitude indication is displayed as a crosshatched area and indicates:
• the FMC landing altitude for destination runway or airport, or
• the landing altitude for departure runway or airport until 400 NM from
departure or one-half the distance to destination, whichever occurs first.
The current barometric reference is displayed below the altitude tape in either
inches of mercury or hectopascals as selected on the EFIS control panel. A
preselected barometric reference can be displayed when STD is displayed.

[Option - Altimeter with QFE]
Altitude reference is selectable between QNH and QFE. QNH is the normal
operating mode. A description of QFE operation is contained in the CDU
Approach Reference Page description in Chapter
11, Flight Management,
Navigation.
Vertical Speed
Vertical speed is displayed to the right of the altitude tape with a tape and pointer.
Vertical speed is digitally displayed above or below the vertical speed display
when vertical speed is greater than 400 feet per minute. It is displayed above with
positive vertical speed and below with negative vertical speed. The selected
vertical speed bug shows the selected vertical speed when in the AFDS vertical
speed (V/S) pitch mode.
Heading/Track Indications
Heading/track information is displayed in the bottom section of the PFD on a
section of the compass rose. Current heading is displayed under a pointer at the
top of the compass rose. The MCP selected heading is displayed as a bug on the
outside of the compass rose and digitally in the left half of the compass rose.
The current heading/track reference (MAG/TRU) is shown in the right half of the
compass rose. A line drawn perpendicular to the edge of the compass rose from
the invisible center depicts the current airplane track.
Traffic Alert and Collision Avoidance (TCAS) Indications
[Option - VSI TCAS advisory]
TCAS resolution advisories are displayed in the attitude indication and vertical
speed indication areas.
Refer to Chapter 15, Warning Systems.
GPWS Warnings
GPWS warnings are displayed in large capital letters between the attitude display
and the heading/track compass rose. Refer to Chapter 15, Warning Systems.

Introduction
The navigation displays provide a color display of flight progress. The displays
consist of the following:
• horizontal situation indicator
• navigation display with MAP,
• radio distance magnetic
APP (approach), VOR, and
indicator
PLN (plan) modes.
The MAP, VOR, and APP modes can be switched between an expanded mode
with a partial compass rose and a center mode with a full compass rose.
Horizontal Situation Indicator (HSI)
The HSI provides heading and track data with VOR navigation or ILS approach
information. The data are normally displayed on a compass rose with 200 degrees
of heading. In the compact EFIS mode, the data are presented on a 360 degree
display.
Radio Distance Magnetic Indicator (RDMI)
The RDMI provides the same information as a conventional RDMI.
Navigation Display - MAP Mode
The MAP mode is recommended for most phases of flight.
[Option - Heading-up display]
Presented heading 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 in both the
expanded and center MAP modes.
10.40.1
Flight Instruments, Displays -
Navigation Displays
Boeing 737 Operations Manual
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.
Navigation Display Information
Heading
Heading is supplied by air data inertial reference system (ADIRS). The 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 navigation display
when in MAP, Center MAP, APP and VOR modes. TCAS is described in Chapter
15, Warning Systems.
Weather Radar
Weather radar information can be displayed on the navigation display when in
MAP, Center MAP, APP and VOR modes. 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
navigation display exceeds the display capability. 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).

• G (green) - active or selected mode and/or dynamic conditions
• M (magenta) - command information, pointers, symbols, fly-to
condition, weather radar turbulence
• C (cyan) - nonactive or background information
• A (amber) - cautions, faults, flags
• R (red) - warnings
• B (black) - blank area, off condition.
