An ADIRU position symbol shows for each ADIRU that is aligned. These symbols make an overlap when the position of each ADIRU is nearly identical.
Two GPS symbols show each GPS position unless the two positions are less than or equal to the diameter of the GPS symbol circle. In this case, only the symbol for the onside GPS shows.

CDS -- ND - PLAN MODE General
To show the plan mode display, select the PLAN position on the EFIS control panel.
The plan mode display shows the FMC flight plan and other navigation data. To see other data, use the map switches on the EFIS control panel.
The air crew uses the plan mode primarily to put in, do a check of, or change a flight plan. The plan mode display always has an orientation in relation to true North up.
Plan Mode Compass Points and True North Up Pointer
The letters N, E, W, and S show at the top, right, left, and bottom of the plan display. These show the compass point orientation of the plan display. A pointer shows next to the N. This shows the North UP orientation of the display.
Airplane Symbol
The airplane symbol is a white outline of an airplane with no fill. The airplane symbol shows the position of the airplane in relation to the flight plan display.
Map Display Range
The range of the plan display is selectable on the EFIS control panel. The selectable ranges are 5, 10, 20 40, 80, 160, 320, and 640 nautical miles (NM).

Two range rings show on the plan display. The diameter of the inner ring is equal to 1/2 of the selected EFIS control panel range. The diameter of the outer ring is equal to the EFIS control panel range.
Numerical range values show at the top and bottom of each range ring. The numerical values on the inner range ring equal 1/4 of the selected range. The numerical value of the outer range ring is equal to 1/2 of the selected range.
Flight Plan Path
The flight plan path shows as a sequence of straight lines between flight legs. Flight legs are the path between two points, usually waypoints.
The flight plan path shows magenta if it is active. If the flight plan path is not active, it shows as a dashed cyan line.
Changes to a flight plan path show white until they become active when you push the EXEC key on the control display unit (CDU).
Flight Plan Waypoints
Flight plan waypoints show selected navigation points or positions along the FMC flight plan path.
Waypoints show as a four point star symbol on the map display. Next to the waypoint is an identifier that shows the name of the waypoint. Waypoints and

identifiers show white if they are not active and magenta if they are active. The active waypoint is the next one on the current airplane path. All other visible waypoints are not active, and thus, white.
You can use the control display unit (CDU) from one waypoint of a flight plan to another. As you select each flight plan waypoint, the waypoint shows at the center of the plan display.
The active waypoint name, estimated time of arrival, and active waypoint distance show in the upper left corner of the expanded map display. The active waypoint name is magenta. Estimated time of arrival and distance to go show white.
Altitude Profile Points
The green altitude profile points are indicators sent by the FMC to identify these active flight plan steps:
-Top-of-climb (T/C)
-Top-of-descent (T/D)
-End-of-descent (E/D)
-Step climb (S/C)
Altitude profile points are in positions on the active flight plan path line at the predicted point of occurrence. If the FMC finds that the predicted point of occurrence is not on the flight plan path line, or if the altitude profile point has already occurred, the altitude profile point does not show.

Ground Speed
Ground speed shows full time in the upper left corner of the centered map display. Ground speed shows in 2-digit format at speeds below 29.5 kts and 3-digit format above 29.5 kts.
Ground speed is white and shows in whole numbers only.
True Airspeed
True airspeed shows full time in the upper left of the centered map display. True airspeed shows in 3 digits for air speeds greater than 101 kts. True airspeed less than 101 knots shows as 3 dashes.
Map Source Annunciation
Map source annunciation shows that the FMC is the source of the map data. FMC shows in green at the bottom of the centered map display.
