BendixKing KDI 574 indicator 066-1069-04

066-1069-04 is the exact Part Number shown on this BendixKing KDI 574 DME indicator. The panel-mounted unit functions as a master display for compatible remote distance-measuring equipment. It presents DME information to the crew and provides the controls required by the approved KDI 574 arrangement. The unit is an indicator and interface, not a self-contained DME transceiver, so operation also depends on the remote equipment, antenna, navigation source and aircraft wiring.

The full -04 suffix is essential for identification. The model is also listed in a zero-padded manufacturer-catalog format as 066-01069-0004. KDI 572, KDI 573 and KDI 574 instruments belong to the same display family but have different system roles and front-control arrangements. A similar outline or connector location is not sufficient evidence of interchangeability.

KDI 574 display functions

The KDI 574 is designed to present distance, groundspeed and time-to-station information received from a compatible DME installation. Distance is derived from the elapsed time between airborne interrogation and ground-station reply. Groundspeed and time-to-station are calculated values based on changing slant range and are most useful when the aircraft is tracking toward or away from the selected DME facility.

BendixKing documentation distinguishes the KDI 574 as a master DME display without the source selector switch used on the KDI 572 arrangement. This difference affects how the installed navigation source and DME channel are controlled. Exact display logic, hold function, lighting and annunciations must be interpreted through the approved operating data for the aircraft rather than assumed from other KDI family members.

Compatible system and signal flow

A representative chain is approved navigation-channel source → KDI 574 master interface → compatible remote DME transceiver → DME antenna and ground station → processed distance information → KDI 574 display. Manufacturer documentation associates KDI 574 displays with compatible equipment such as the KDM 706A where the combination is approved. The remote transceiver supplies the radio and ranging function; the KDI 574 supplies the cockpit presentation and control interface.

An approved system may also provide information to a KDI 573 slaved display at an additional crew position. The KDI 573 does not replace the KDI 574 master. Before ordering any associated unit, compare complete Part Numbers, installed wiring, data format, connector, lighting and the aircraft equipment list. Products listed together in the avionics category are related by possible system use and are not represented as direct substitutes.

Plate data, installation and testing

The authentic gallery photograph shows a KDI 574 plate with Part Number 066-1069-04, serial number 84806, a stated weight of 0.7 lb, approximately 0.32 kg, and TSO C66a and DO-160 references. These values belong to the photographed -04 unit. Exact panel depth, cutout, connector pin assignment and supply requirements have not been inferred from the KDI 572 or KDI 573.

Receiving inspection should verify the model legend, exact plate, serial number, display window, bezel, mounting features, rear connector, overhaul release and preservation. An installation test should cover power-up, illumination, display segments, data validity, channel response, hold behavior and communication with the compatible remote transceiver. DME performance also depends on the antenna, coaxial cable, navigation-channel source, transceiver and line-of-sight to the ground station.

Overhauled supply and ordering information

This 066-1069-04 KDI 574 is offered in Overhauled condition from partner stock with a six-month warranty. The quotation will confirm the allocated serial number, overhaul organization, release certificate, test status and included accessories.
