KMD 540 pages and weather module

The front bezel includes MAP, WX, TRFC, TERR and AUX keys, line-select keys, cursor and range controls, card slots and power or brightness controls. The labels describe available interface categories but do not guarantee that every function is enabled in every aircraft. Each page requires its approved source, software, database and configuration.

The authentic side view confirms a KAC 501 Digital Weather Radar Module, Part Number 071-00159-0111, installed on this exact -1101 unit. That module provides the documented weather-related part of the photographed configuration. No additional traffic or terrain module is assumed where a corresponding exact label was not confirmed.

Exact plate data for the -1101 unit

The manufacturer plate identifies a KMD 540 MFD with Part Number 066-04035-1101. It lists 27.5 VDC at 1.0 A or 13.75 VDC at 2.0 A and gives a weight of 5.5 lb, approximately 2.5 kg. TSO C113, TSO C110a and DO-178B Level C are shown on the photographed plate.

The serial marking is not repeated in this card because it was not sufficiently clear for error-free transcription. Exact dimensions, rear connector assignment, cooling requirements, interface protocols and database-card configuration should be taken from approved installation data for the complete -1101 suffix rather than copied from a related KMD display.

Installation, signal path and test checks

A typical weather path is an approved weather-radar sensor and aircraft interface → installed KAC 501 module → KMD 540 processing and display → crew selection using the WX controls. Other map, traffic, terrain and auxiliary paths require their own compatible sources. The display cannot create valid information when an upstream source, database or data bus is absent.

Before installation, confirm the complete Part Number, panel and rack fit, connector keying, power supply, circuit protection, cooling, KAC 501 configuration, aircraft interfaces, software and database media. Functional testing should cover screen quality, brightness, controls, enabled pages, range selection, valid-data indications and failure annunciations according to the approved maintenance procedure.

A missing page or incorrect presentation can originate in the display, KAC module, receiver, antenna, database, wiring or configuration. Technicians should examine the entire source-to-display chain before condemning the KMD 540. Another KMD 540 suffix is not automatically interchangeable merely because the front dimensions appear similar.

Overhauled supply and ordering information

This 066-04035-1101 KMD 540 is offered in Overhauled condition from partner stock with a six-month warranty. The quotation will confirm the allocated serial number, overhaul source, release certificate, screen test, installed KAC 501 status, software and database condition, and any accessory explicitly included.

For an inquiry, specify Part Number 066-04035-1101, model KMD 540, aircraft type, installed source equipment, required software or database, quantity and certification. Weather radar sensor, antenna, other modules, rack, cards, connector and wiring are supplied only when expressly listed. Related products can be reviewed in the Garmin / BendixKing / Honeywell / Collins category; related equipment is not automatically interchangeable.

The receiving organization should compare modification labels and verify that the intended aircraft has approved data sources for every required operational page.

Configuration control is especially important when the aircraft uses several data sources. The quotation and receiving inspection should identify installed modules, software status and database media separately, so the maintenance organization can compare them with the approved aircraft configuration before fitment.
