scale is in 2.5 degree increments.
A pointer indicates bank angle in increments of 10, 20, and 30 degrees. Single
marks indicate 45 and 60 degrees of bank. A small rectangle under the bank angle
pointer indicates slip and skid conditions. Bank angle is also represented by the
attitude of the airplane symbol against the horizon line and pitch scale.
A pitch limit indication is displayed at low speeds when the flaps are up and at all
times when the flaps are down.
Steering Indications
The flight director steering indications are displayed when the associated flight
director switch is on.
TCAS resolution advisories are displayed in the attitude indication area. Refer to
Chapter 15, Warning Systems.
The flight path vector (FPV) symbol represents airplane flight path angle
vertically and drift angle laterally. The flight path vector is displayed on the PFD
when the EFIS control panel FPV switch is selected on, or the MCP FPA reference
switch is selected on. The FPV shows the Flight Path Angle (FPA) above or below
the horizon line and drift angle left or right of the pitch scale’s center. The FPA
uses inertial and barometric altitude inputs. The vertical FPA is unreliable with
unreliable primary altitude displays.
The flight path angle (FPA) symbol shows the selected flight path angle when the
MCP FPA reference switch is selected on and either the flight director or autopilot
is engaged.

The FPV and FPA symbols are displayed in two sizes and brightness levels. The
large, bright FPV/FPA symbols are displayed when the previously stated
selections are made and the flight director is off. The small, dim FPV/FPA
symbols are displayed when the previously stated selections are made and the
flight director is displayed.
Radio Altitude
The current radio altitude is displayed in the bottom center of the attitude
indication area when radio altitude is below 2,500 feet AGL.
Instrument Landing System Indications
ILS glide slope and localizer deviation, frequency/identification, DME, course,
and marker beacon indications are provided.
The approach reference information appears above and to the left of the attitude
display. The ILS station identification or frequency, course, and (if available)
DME are displayed.
The marker beacon indication (OM – outer marker, IM – inner marker, or MM –
middle marker) is displayed in the upper right corner of the attitude display area.
The glideslope pointer and scale appear on the right side of the attitude indication.
The localizer pointer and scale appear at the bottom of the attitude indication.
Integrated Approach Navigation (IAN) Indications
FMC glide path and FAC deviation, approach identifier, distance, and course are
provided.
The approach reference information appears above and to the left of the attitude
display. The IAN deviation source annunciation is below the approach data.
IAN glide path and FAC deviation indications and alerts are displayed like ILS.
Deviation indications appear when a valid IAN approach is selected. IAN
approach deviations are not available with QFE selected in the FMC.
Approach Minimums
The selected radio altitude or barometric approach minimums set on the EFIS
control panel are displayed near the bottom left of the altitude display.

Heading/Track Indications
Selected heading/track information is displayed in the bottom section of the PFD
on the Mini-map. Current heading is displayed under a pointer at the top of the
compass rose. The MCP selected heading bug is displayed on the outside of the
compass rose. The MCP selected track bug is displayed on the inside of the
compass rose.
Heading or track is displayed based on the position of the MCP HDG/TRK
reference switch. The selected heading or selected track is annunciated below and
to the left of the airplane symbol. The current heading/track reference
(MAG/TRU) is shown below and to the right of the airplane symbol. A line drawn
perpendicular to the edge of the compass rose from the invisible center depicts the
current airplane track.
Engine Fail, GPWS, and PWS Alerts
Engine fail, GPWS, and PWS alerts are displayed in large capital letters between
the attitude display and the heading/track compass rose. Refer to Chapter 15,
Warning Systems.
