066-1048-02

Radar altitude and compatible system path

A typical signal path is KRA 405 transmitter → approved transmit antenna → reflection from the surface → approved receive antenna → KRA 405 receiver and processor → compatible analog indicator or aircraft system. Radar altitude is geometric height above the reflecting terrain or water and is therefore different from pressure-derived barometric altitude.

The exact front panel has separate connections marked RCVR and XMTR plus a covered aircraft connector. Partner source data associates the KRA 405 family with compatible KNI 415 and KNI 416 indicators, but the specific indicator and wiring for 066-1048-02 must be confirmed from the aircraft documentation. Related equipment is not assumed to be included.

Exact -02 identification boundaries

The photographs identify this unit as a Bendix/King KRA 405 with Part Number 066-1048-02 and source serial reference 6552. The authentic views preserve the enclosure, mounting rails, RF connections, caution label and seals. No value has been transferred from the exact -00 plate or from the later KRA 405B.

Reliable exact figures for supply current, weight, measuring range, accuracy, operating frequency, overall dimensions, connector pin assignment and environmental limits were not independently confirmed in authoritative open documentation for the -02 suffix. These characteristics should be taken from the approved KRA 405 component maintenance and installation data tied to 066-1048-02.

Installation and functional verification

Before installation, confirm Part Number 066-1048-02, serial and modification records, rack, connector keying, approved power supply, circuit protection, antenna models, antenna spacing, coaxial-cable loss, bonding, output interface, indicator compatibility and any trip or warning circuits. Physical fit alone is not evidence of an approved replacement.

Testing should verify system response at the approved radar-altitude test points, indicator operation, warning or trip functions where fitted, RF antenna paths and aircraft interfaces. A fault can originate in the receiver/transmitter, indicator, antenna, coaxial cable, power supply, bonding or wiring. The complete chain should be tested before the KRA 405 is condemned.

Any proposed substitution with 066-1048-00, a KRA 405B or a modern filtered radar altimeter requires approved engineering data. Such a change can require different wiring, rack, outputs, antennas, configuration or certification. The suffix must therefore remain visible in the product title, URL, SEO data and quotation.

Overhauled supply and ordering information

This 066-1048-02 KRA 405 is offered in Overhauled condition from partner stock with a six-month warranty. The quotation will confirm the allocated serial, overhaul source, current bench-test status, release certificate and the precise accessories included with the unit.

For an inquiry, specify Part Number 066-1048-02, model KRA 405, aircraft type, installed indicator, antenna configuration, quantity and required certification. Antennas, indicator, rack, mating connector and coaxial cables are included only when expressly stated. Related avionics can be reviewed in the Garmin / BendixKing / Honeywell / Collins category; related radar-altimeter components are not automatically interchangeable.

Receiving inspection should document connector condition, RF-port protection, mounting surfaces and seals before installation. This record helps distinguish component condition from transport or installation damage during later troubleshooting.
