Rising Runway

The rising runway shows when there is a LOC signal capture and the radio altitude is below 2500 feet. The symbol goes out of view above 2500 feet. The rising runway symbol is green with a magenta stem.

The rising runway symbol represents the radio altitude above the runway. It moves laterally with the localizer deviation pointer to show localizer deviation. The symbol starts to move when the radio altitude is 200 feet. It touches the airplane symbol when the radio altitude is 0 or at touchdown.

NCD Display

When the ILS data goes to an NCD condition, the CDS shows the localizer and glideslope scales and removes the pointers.

Fail Display

The amber LOC flag replaces the localizer deviation pointer

and scale when the localizer receiver function has a failure. The

amber G/S flag replaces the glideslope deviation pointer and

scale when the glideslope receiver function has a failure.

ILS - EXPANDED ILS DISPLAY

General

To show ILS displays on the CDS, set the EFIS control panel mode selector to the APP position. You must also tune a valid ILS frequency on the NAV control panel.

Normal Display

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.

NCD Display

When the ILS data goes to an NCD condition, the CDS shows the localizer and glideslope scales and removes the pointers.

Fail Display

For invalid ILS data, the CDS replaces the localizer deviation

scale and indicator with the amber LOC flag when the localizer

receiver fails. The amber G/S flag replaces the glideslope

deviation scale and pointer when the glideslope receiver fails.

ILS - CENTERED ILS DISPLAY

General

To show the centered ILS NAV display, push the CTR switch on the EFIS control panel mode selector switch.

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.
