Normal Displays

The glideslope deviation pointer and scale show to the right of the HSI display. The glideslope pointer is magenta and the scale is white.

The glideslope scale is the standard four dot scale. Each dot equals 0.35 degrees of deviation. The pointer gives fly-to commands 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 show in the center of the HSI compass card. The localizer deviation indicator is magenta and the scale is white.

The localizer scale is the standard four dot scale. Each dot is equal to 1 degree of deviation. The deviation indicator shows the deviation to the left or the right of the runway centerline.

The NAV data source shows in white in the upper right corner of the display. It shows the source of data for the ILS display. The active ILS frequency shows to the right of the NAV data source. The ILS frequency display shows the active ILS frequency and the selected course. If the ILS ground station transmits a morse coded station identifier, then the letter identifier replaces the numeric frequency when the receiver captures the ground station signal.
