Honeywell KI 825 EHSI 066-01179-0104

066-01179-0104 is the exact Honeywell/BendixKing Part Number for this KI 825 Electronic Horizontal Situation Indicator. The instrument is a cockpit display intended to present compatible heading and navigation information in a consolidated horizontal-situation format. It is an indicator and crew interface, not an independent heading sensor, navigation receiver or flight-management computer.

The complete -0104 suffix must be retained when checking a replacement. Other KI 825 units can look alike from the front while carrying a different full Part Number, internal configuration or modification status. Approval should be based on the aircraft equipment list, connector and wiring data, the exact identification plate and the applicable installation instructions rather than on the KI 825 model legend alone.

Horizontal navigation display function

In a compatible installation, the KI 825 receives heading and navigation data from the approved aircraft sources and presents the information to the crew on its electronic display. The exact symbols, course information, bearings, mode labels and annunciations depend on the connected equipment and selected operating mode. The dark screen in the product photographs is an unpowered display and does not indicate a failure.

A simplified chain is approved heading or attitude-heading source plus compatible navigation receiver or management system → aircraft interface and wiring → KI 825 processing and display → crew interpretation and, where approved, flight-control monitoring. The KI 825 does not measure magnetic heading or receive radio-navigation signals by itself, so faults can also originate in upstream sensors, receivers, interface units or wiring.

Exact identification and electrical data

The authentic side plate identifies the unit as a KI 825 Electronic Horizontal Situation Indicator and gives Honeywell BRGA Part Number 066-01179-0104. A second manufacturer reference, Honeywell Grimes Part Number 80-5205-2-4, is also visible. Both identifiers should be retained in maintenance records and quotation checks because they appear on the exact photographed unit.

The same plate states operation from 14/28 VDC and a maximum weight of 3.00 lb, approximately 1.4 kg. The photographed identification information includes serial number 0593 and Date of Manufacture 0503. The date marking is preserved as an identification detail; it is not converted into a separate YOM attribute because the exact date-code interpretation was not independently confirmed.

Exact dimensions, connector type, pin assignment, input current, display interfaces and environmental qualification values were not confirmed from an authoritative open manual for this exact suffix. They must be taken from the approved KI 825 component or installation data. No values have been imported from a visually similar EHSI, and no aircraft applicability is claimed without documentation.

Installation and troubleshooting checks

Before installation, confirm Part Number 066-01179-0104, alternate reference 80-5205-2-4, aircraft voltage, panel cutout, mounting hardware, connector keying, modification status, display-interface configuration and approved upstream sources. A correct physical fit does not establish electrical compatibility, especially when another EHSI suffix or system generation uses a similar bezel.

Functional testing should verify power-up, display clarity, control response, heading presentation, course or bearing data and applicable mode annunciations using the aircraft maintenance procedure. A blank, unstable or incorrect presentation can result from power distribution, dimming, aircraft wiring, heading source, navigation receiver or interface equipment. System troubleshooting should isolate those inputs before the KI 825 is removed or condemned.

The main studio image provides a clear front view of the display, bezel and lower controls. The authentic gallery photograph preserves the exact side labels, serial data, weight, voltage and alternate Part Number for technical comparison. Cosmetic restoration of the main catalog image does not replace the condition assessment and certification of the serial-numbered unit supplied.
