The glideslope deviation pointer and scale show at the right of the NAV display. The glideslope deviation pointer is magenta and the scale is white.
The glideslope scale is the standard four dot scale where each dot equals 0.35 degrees of deviation. The glideslope deviation pointer gives fly-to signals to intercept the glideslope beam. The course pointer points to the number that you set on the DFCS MCP. For ILS, you use the DFCS MCP course selector to enter the ILS course (airport runway heading).
The localizer deviation indicator and scale shows at the bottom of the NAV display. The localizer scale is white and the localizer deviation indicator is magenta.
The deviation scale is the standard four dot scale. One dot is equal to 1 degree of deviation. The localizer deviation indicator shows the deviation to the left or right of the runway centerline.
The NAV data source shows in white at the upper right corner of the display. It shows the source of the data for the ILS displays. To the right of the NAV data source is the active ILS frequency display.
The ILS frequency display shows the active ILS frequency and the selected course. If the ILS ground station transmits a morse coded station identifier, the letter identifier replaces the numeric frequency when the receiver captures the ground station signal.
