The NAV control panels have an active frequency display window and a standby frequency display window. The frequency that shows in the active frequency display window is the frequency that the navigation radios use for operation. The standby frequency display window shows the next frequency you will use.

The transfer switch is a momentary action switch. It transfers the frequency in the standby frequency display window to the active frequency display window. When you push the switch, the frequency that is in the active frequency display window transfers to the standby frequency display window.

The frequency select control is a continuous rotary knob. There is an inner knob and an outer knob. The outer knob sets the tens and ones. The inner knob sets the tenth and one hundreth numbers.

At power up, the frequency displays show the last frequency entry before power down.

The NAV control panel continuous BITE function monitors the operation. The NAV control panel shows FAIL in the active and the standby frequency display windows when there is a failure. The monitor in the NAV control panel monitors the 28v dc input. If the monitor does not get the 28v dc, the frequency display windows are blank.

DME SYSTEM - GENERAL DESCRIPTION
General The DME system has two DME interrogators and two antennas. Description The interrogators get manual tune inputs and flight management computer system (FMCS) autot

General
These are the components in the flight compartment that have an interface with the DME system: · FMC source select switch · Left inboard and outboard display units · Left

DME Outputs
Each DME interrogator has two output buses. One output bus supplies data to the on-side flight control computer (FCC). DME 1 sends data to FCC A and DME 2 sends data to FCC B. the other Output bus

General
The navigation (NAV) control panels supply frequency inputs and test commands to these navigation radios: · DME · ILS · VOR. When you put a paired VOR or ILS fre

Operation
The CPU uses tune inputs to tune the frequency synthesizer. The CPU give a signal to the transmitter to send interrogation pulses. The transmit pulses go through a circulator then to the DME antenn

DME SYSTEM - SELF TEST
Self Test Push the test switch on the DME interrogator to start a DME selftest. Front Panel Displays The LED status indicators go through this sequence: · The LR

General
During a ground test or a self test, the display units show these indications: · The DME fail condition for two seconds · The DME NCD condition for the next two seconds ·
