Display functions and installed KMD modules

The front panel carries MAP, WX, TRFC, TERR and AUX keys, line-select buttons, range and cursor controls, power and brightness controls, and card slots. These controls let the crew select and manage supported information. Availability of a page depends on the corresponding aircraft source, wiring, configuration and current database rather than the label on the bezel alone.

The authentic gallery view documents three installed modules on this exact unit: KAC 501 Digital Weather Radar Module Part Number 071-00159-0111, KAC 504 Traffic Module Part Number 071-00166-0411 and KAC 502 EGPWS Module Part Number 071-00158-0211. Their labels establish the photographed configuration, but they are not represented as separately supplied loose components.

Exact identification and electrical data

The manufacturer plate identifies a KMD 540 MFD with Part Number 066-04035-0301 and serial number 1751. It lists 27.5 VDC at 1.0 A or 13.75 VDC at 2.0 A and a weight of 5.5 lb, approximately 2.5 kg. TSO C113, TSO C110a and DO-178B Level C appear on the exact plate.

Those values belong to the photographed -0301 display and are not transferred from the -0101 or -1101 suffix. Exact dimensions, rack clearance, connector pin assignment, cooling limits, database-card requirements and supported interface protocols should be confirmed from approved data for 066-04035-0301 before installation.

Signal path, installation and testing

A representative chain is approved navigation, weather-radar, traffic or terrain source → installed KAC module and aircraft interface → KMD 540 processing and display → crew selection through the bezel controls. The exact path varies with aircraft configuration. A missing overlay can originate in a sensor, antenna, module, data bus, database, wiring or configuration rather than in the display itself.

Before installation, verify the complete Part Number, panel and rack dimensions, rear connector, power supply, circuit protection, cooling, installed modules, software, database media and every enabled source interface. Functional testing should include power-up, screen brightness, control response, enabled pages, range selection, valid-data annunciations and failure messages under the applicable maintenance procedure.

The display must not be treated as interchangeable with another KMD suffix because the front panel looks identical. Module composition, software, databases, electrical configuration and aircraft approval all matter. A replacement or exchange should retain traceable records for the serial-numbered unit and document the installed KAC modules actually accepted for the aircraft.

Overhauled supply and ordering information

This 066-04035-0301 KMD 540 is offered in Overhauled condition from partner stock with a six-month warranty. The quotation will confirm the allocated serial, overhaul source, release certificate, screen test, software and database status, and whether any rack, connector, card or installation accessory is included.

For an inquiry, specify Part Number 066-04035-0301, model KMD 540, aircraft type, installed source equipment, required module configuration, software or database requirement, quantity and certification. Antennas, sensors, rack, wiring and loose accessories are included only when expressly listed. Related products can be reviewed in the Garmin / BendixKing / Honeywell / Collins category; related equipment is not automatically interchangeable.

Maintenance records should identify the software level and database cycle tested at release, because configuration details can affect the pages available after installation.
