General - раздел Механика, DISTANCE MEASURING EQUIPMENT - INTRODUCTION The Navigation (Nav) Control Panels Supply Frequency Inputs And Test Commands...

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 frequency into the navigation control panel, it also goes to the DME interrogator. The DME tunes a DME frequency in the range of 108MHz to 117.95MHZ. Set the frequency on the navigation control panel for these audio outputs:

· VOR and DME station identification

· ILS and DME station identification.

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

Operation
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 navi

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 ·
