Honeywell / King Radio KDM 705 DME Module Description

Functions

Airborne distance measuring equipment (DME) transceiver module, operating in the UHF band for precision distance measurement between aircraft and ground stations. Provides slant range distance information in nautical miles through pulse interrogation techniques. Integrates with flight management systems, navigation displays, and other avionics systems via ARINC 429 data buses. Supports multiple operational modes including normal, standby, and ground test. Utilizes pulse pair transmission and reception with precise timing measurement to calculate aircraft distance from DME ground stations.

Platforms

Standard King Radio KX155/165 navigation system module requiring 14/28VDC power, interfaces via 37-pin D-sub connector to NAV receiver for channeling control and DME hold functions. Operates in standard avionics rack with DZUS rail mounting, communicates through ARINC 429 or analog interfaces for distance/groundspeed/time-to-station data output. Requires external antenna connection via BNC/TNC connector, typically interfaces with CDI/HSI displays and flight management systems. Common installations include general aviation aircraft instrument panels, corporate aircraft avionics suites, and retrofit navigation system upgrades. Compatible with VOR/LOC/GS receivers for integrated navigation solutions.

Applications

Provides precise slant range distance information for RNAV and conventional navigation, facilitating instrument approaches, accurate position reporting to ATC, and defining airspace boundaries. Essential for flight management systems to calculate time/distance to waypoints, support fuel burn predictions, and optimize flight profiles in civil and military aircraft.

Accessories

Requires KNS 80 or KNS 81 navigation system mainframe for operation. Interfaces through 15-pin D-sub connector to mainframe backplane for power, control, and data exchange. Utilizes dual 50-ohm BNC connectors for DME antenna input/output with internal diplexer. Features 44-pin edge connector for mainframe slot insertion. Requires external DME antenna with appropriate coaxial cabling. Compatible with standard ARINC 429 digital data bus through mainframe interface. Includes built-in self-test capabilities accessible through mainframe controls.

Interfaces

ARINC 429, RS-232 serial, BNC antenna connector, 15-pin D-sub connector for data and power.

Specifications

The DME module provides distance measuring equipment functionality, operating in the 962-1213 MHz frequency range, and utilizes a dual-transceiver design for redundancy. It interfaces with the aircraft's navigation system via ARINC 429 data bus for data exchange (distance, groundspeed, and time-to-station) and is typically installed within the avionics bay. Primary application is enroute and approach navigation in aircraft.
