the FMC or pilot selected
primary alternate airport.
Displays up to four
alternate airports when the
APT key is selected.
Offscale airports (only with
1280NM scale selected),
directional arrow relative to
airplane position or PLAN
center point and distance.
Symbol Name Remarks
Airplane symbol (W) Current airplane altitude is the bottom of
the triangle. Current airplane lateral
position relative to terrain is the point of the
triangle.
Enroute swath (B)
(dashed line)
Indicates area of the map that is shown on
the VSD. Displayed full time when VSD is
selected. During turns, the swath edge
leading the turn opens in the directrion of
the turn.
Selected altitude bug
and line (M)
Bug indicates the altitude set in the MCP
altitude window. When the selected altitude
is off scale, the bug is parked at the top or
bottom, with only one half the bug visible.
Dashed line extends from bug to
background display boundary. Line does
not park.

BARO minimums
pointer and line (G)
Pointer indicates the barometric minimums
selected on the EFIS control panel.
Dashed line extends from pointer to
background display boundary.
Pointer and line turn amber when airplane
descends below selected minimum altitude.
Reset with the RST switch on the EFIS
control panel.
Decision gates (W, A) Indicates suggested points where airplane
should be path and speed stable on
approach. Gates are placed on the 3 Degree
Reference Line or FMC Approach
Glidepath Angle Line:
• at 1000 feet above field
elevation (W)
• at 500 feet above field elevation
(A)
Decision gates that are below the missed
approach waypoint altitude will not be
displayed.
Flight path vector (W) Fixed length line indicates current flight
path angle and rotates about the point of the
triangle.
Angle of the line is dependent on the
vertical speed and ground speed of the
airplane.
MCP selected vertical
speed vector (M)
Dashed line indicates the selected vertical
speed as a target angle when the MCP V/S
mode is selected.
Extends to the edge of the background
display and rotates about the point of the
triangle.

Range to target speed
dot (G)
Indicates where the airplane will achieve
the FMC or MCP target speed. If the
airplane is within 5 knots of the target
speed the dot will be blanked. If the
airplane increases 10 knots or more faster
than the target speed the dot will reappear.
Displayed at the end of the Flight Path
Vector as an unfilled dot if the target speed
will not be achieved within the vector
length.

The arrow indicates traffic
climbing or descending at a
rate greater than or equal to
500 fpm. At rates less than
500 fpm, the arrow is not
displayed.
The number and associated
signs indicate altitude of
traffic in hundreds of feet
relative to the airplane.
The number is below the
traffic symbol when the
traffic is below, and above
the traffic symbol when the
traffic is above the airplane.
Absence of the number
implies altitude unknown.
