· Push the test switch on the NAV control panel.

To see the ILS test on the NAV display, you must select the approach (APP) mode on the EFIS control panel mode selector. This is the display sequence that shows on the CDS during the ILS test:

· For the first 3 seconds, one dot left of localizer deviation and one dot up of glideslope deviation

· For the next 3 seconds, one dot right of localizer deviation and one dot down of glideslope deviation

· Displays return to normal indications.

Purpose
The multi-mode receiver (MMR) contains the instrument landing system and the global positioning system functions. This section only covers the instrument landing system function. The instr

· AC - alternating current · ACP - audio control panel · alt - alternate · altn - alternate · app - approach · ARINC - Aeronautical Radio, Inc.

Description
The receivers get manual tune inputs from the navigation (NAV) control panels. The VOR/LOC antenna and the localizer antenna send localizer signals through the localizer antenna switches t

Power Inputs
The P18-1 circuit breaker panel contains the MMR 1 and NAV CONT PNL 1 circuit breakers. The circuit breakers receive 115v ac from the 115v ac standby bus section 1. The circuit breakers supply powe

Digital Outputs
Each MMR has two output data buses. Output data bus 1 goes to the FCCs. Output data bus 2 goes to many components. The FDAU receives ILS data and status of the MMR receivers. The FDAU proc

Navigation/Displays Source Select Panel
  The VHF NAV switch on the navigation/displays source select panel is a three position switch. The positions are; BOTH ON 1, NORMAL, and BOTH ON 2. This switch changes the source of

General
  The multi-mode receivers (MMRs) get RF inputs from these antennas: · VOR/LOC antenna on the vertical stabilizer · Localizer antenna in the nose radome · G

General
When you tune an ILS frequency on the NAV control panels, discrete signals go to the DEUs to tell if the frequency is an ILS or VOR frequency. Each NAV control panel sends the discrete signal to th

Operation
The NAV control panels have an active frequency indicator and a standby frequency indicator. The frequency that shows in the active frequency indicator is the frequency the navigation radios use fo

Discrete Interfaces
  The REU uses the open discrete to select ILS audio. The DEUs use the ground discrete to set the ILS displays. The NAV control panel sends the 28v dc to the FCCs when an ILS frequenc

Receiver Functional Description
  All inputs to the receiver go through a high intensity radiated frequency (HIRF) filter. This filter provides protection to internal circuits. Tune inputs from the NAV cont

DFCS Controls
The digital flight control system (DFCS) mode control panel (MCP) supplies runway heading data to the display electronics unit (DEU) for ILS displays. You use the DFCS MCP course selector to set th

Audio Control Panel Controls
The audio control panels (ACPs) lets the crew listen to ILS station audio or the morse code station identifier. You use the ACP receiver switches to select the ILS audio you want to listen

Indications
When the selector is in the OFF position, the localizer and glideslope deviation bars do not show. When the selector is in the APP position, the localizer and glideslope deviation bars show. When y

Normal Display
The localizer deviation pointer and scale show at the bottom of the attitude display. The scale is a standard four dot scale. One dot equals 1 degree of deviation. The deviation indication shows de

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

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 fo

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 sca
