function in the MMRs receive inputs from these antennas:
* VOR/LOC antenna
* Localizer antenna
* Glideslope antenna.
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 to the MMRs.
The localizer antenna switches select the VOR/LOC antenna or
the localizer antenna as the source of RF input to the MMR. The
glideslope antenna sends glideslope signals to the multi mode
receivers.
The multi-mode receivers send ILS deviation data to these
LRUs:
* DEUs
* REU
* GPWC
* FCC
* FDAU
* FMC
* Standby attitude indicator.

Electronic Equipment Compartment
The multi-mode receivers (MMRs) are in the electronic
equipment compartment. MMR 1 is on the E1-2 shelf. MMR 2
is on the E1-4 shelf. The LOC antenna switches are on the side
of the E1 rack.
Nose Radome
The glideslope and localizer antennas are in the nose radome.
The glideslope antenna is above the weather radar antenna.
The localizer antenna is below the weather radar antenna.

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 power to the multi mode receiver 1 and the captain’s
NAV control panel.
The P18-1 circuit breaker panel also contains the NAV SENSOR
DC 1 circuit breakers. The circuit breakers receive 28v dc from
the 28v dc standby bus and the 28v dc bus. The circuit breakers
send 28v dc to the NAV control panels and to the integrated
flight system accessory unit (IFSAU). The IFSAU contains
circuits that supply a discrete signal to the LOC antenna
switches for operation. The IFSAU uses the 28v dc from the NAV
control panel and a discrete signal from the FCC to set the logic
to send a discrete signal to operate the LOC antenna switches.
The P6-1 circuit breaker panel contains the NAV CONT PNL 2
and the MMR 2 circuit breakers. The circuit breakers receive
115v ac from the 115v ac transfer bus section 2. The circuit
breakers supply power to the first officer’s NAV control panel
and the multi mode receiver 2.
The P6-1 circuit breaker panel also contains the NAV SENSOR
DC 2 circuit breakers. The circuit breakers receive 28v dc from
the 28v dc standby bus and the 28v dc bus. The circuit breakers
send 28v dc to the NAV control panels and to the integrated
flight system accessory unit (IFSAU). The IFSAU contains
circuits that supply a discrete signal to the LOC antenna
switches for operation. The IFSAU uses the 28v dc from the NAV
control panel and a discrete signal from the FCC to set the logic
to send a discrete signal to operate the LOC antenna switches.
When you tune an ILS frequency on the NAV control panels, 28v
dc goes to the on-side FCC and LOC antenna switch. The FCC’s
use the 28v dc for mode selection. The LOC antenna switches
use the 28v dc for operation.
