CDS -- ND - EXPANDED MAP MODE
A wind pointer shows below wind angle. The wind pointer turns around itself as a function of wind direction to show wind angle.
Wind speed and angle do not show if true airspeed is less than 101 knots. The digital readout shows dashes, and the wind pointer goes blank.
Vertical Deviation
Vertical deviation shows at the top of descent and during descent only.
The vertical deviation feature has a magenta diamond shaped pointer that moves against a white fixed scale. The vertical deviation pointer shows the airplane vertical path, and the center of the scale shows the airplane.
The vertical track deviation scale shows +/- 400 feet from the center mark to the outer marks. Maximum pointer movement extends more than the scale outer marks to a limit of +/- 430 feet. When vertical deviation is more than the maximum scale range, a numeric readout of deviation shows above or below the scale. The maximum numeric readout is 9999.

CDS -- ND - CENTERED MAP General
To show the centered map display, select the map position on the EFIS control panel. Push the CTR button on the EFIS control panel if the expanded map display shows. This changes the display to the centered map display.
The map display shows the FMC flight plan and other navigation data. To see other map data, use the map switches on the EFIS control panel.
Airplane Symbol
The airplane symbol shows at the center of the centered map mode. The airplane symbol is a white triangle with no fill. The airplane symbol does not move. Other pointers and displays move in relation to the airplane symbol.
Compass Rose
A compass rose shows on the centered map display. The compass rose has index marks at 5 degree intervals and numerics at 30 degree intervals. The compass rose turns around the airplane symbol.
Airplane Present Heading
Airplane present heading shows as a white numerical value in the center above the compass rose in a box. Directly below the heading box is the white heading

pointer. The heading pointer does not move. To the left of the heading box is the green HDG annunciation.
Track Line
The white track line shows above the airplane symbol and extends to the compass rose arc. The track line shows the current track of the airplane.
Airplane Present Track
The track extends from the airplane symbol to the compass rose and turns along the compass rose to accurately indicate present track.
MAG/TRU Annunciation
The MAG/TRU annunciation is to the right of the airplane heading value. MAG shows if the heading value has a reference to magnetic North. TRU shows if the reference is to true North.
MAG/TRU Highlight Annunciation
The MAG/TRU highlight annunciation gives alerts the crew when there is a change from TRU to MAG or from MAG to TRU. It also gives alerts the crew during landing if the reference is TRU.
The MAG/TRU highlight annunciation shows for these conditions:
- 430 -

- For 10 seconds, on a transition from TRU to MAG,
and is green
- When TRU is the reference, and is white
-When is a specified descent rate, and TRU is the reference; in this case the symbol is amber and goes on and off for the first 10 seconds.
Map Display Range
The range of the expanded map display is selectable on the EFIS control panel. The selectable ranges are 5, 10, 20 40, 80, 160, 320, and 640 nautical miles (NM).
The range of the display is measured from the nose of the airplane symbol to the compass rose arc.
The range value shows white next to the track line at the mid point between the airplane symbol and the compass rose arc. The range value shows forward of and behind the airplane symbol. Each value is equal to one quarter of the selected range.
Range Marks
Two range marks show on the track line of the centered map display. One is forward of the airplane position, and one is behind the airplane position. The marks are white. Each mark shows 1/4 of the selected range. For example, if 80 NM range is selected, each mark shows 20 NM.
