Remote Navigation/ Communication Tranceiver Model ADR-7050 Introduction This guide describes the features and operation of the Remote Navigation/Communication Transceiver, model ADR-7050 from L-3 Communications Avionics Systems, Inc. The ADR-7050 is controlled by individual cockpit displays. Refer to your Aircraft Flight Manual Supplement (AFMS) and the documentation supplied with your cockpit display for detailed instructions. This guide is to be used as an informational supplement.
Equipment Description • Adjustable volume control • Intercom function that enables the pilot and copilot to communicate with each other via their headphones without speaker output. This function is only used if the aircraft’s audio panel does not have an intercom function. • Auto squelch function with manual override. The ADR-7050’s auto squelch feature sets a radio noise threshold to silence unwanted noise. The auto squelch level is set using a maintenance computer.
Operating Instructions The localizer receiver is tuned when an appropriate localizer frequency is selected on the nav radio. The localizer receiver outputs the appropriate CDI signal to the flight system based on where the aircraft is, relative to the center line of the runway. The localizer receiver also outputs the nav audio signal and automatically decodes the Morse code identifier from the localizer station.
