BendixKing KCI 310 indicator 066-3020-12

066-3020-12 is the exact Part Number of this BendixKing KCI 310 flight director indicator. The panel-mounted instrument combines attitude presentation with flight-director steering commands and dedicated validity flags. Its display gives the pilot an immediate visual relationship between aircraft attitude, the fixed aircraft symbol, bank reference and the command cue generated by compatible flight-control equipment. The KCI 310 is an indicating unit within an approved system; it is not a complete autopilot or an independent attitude source.

The complete -12 suffix is important when identifying the unit. Instruments carrying the KCI 310 family name can have similar front faces while differing in electrical configuration, lighting, internal modification status or approved system application. Part Number 066-3020-12 must therefore be matched to the installed identification plate, aircraft equipment list, connector, mounting arrangement and approved wiring data. Compatibility should never be inferred from the model name or panel dimensions alone.

Attitude and flight-director presentation

The attitude presentation helps the pilot interpret pitch and bank relative to the symbolic horizon. The command cue displays steering guidance calculated elsewhere in the flight-director or autopilot system. The pilot follows the command indication as prescribed by the aircraft flight manual, while the indicator positions the cue from electrical inputs supplied by the associated computer. The instrument does not calculate a navigation route or move aircraft controls by itself.

Official BendixKing pilot guidance describes separate ATTITUDE and COMPUTER warning flags. The attitude flag warns when valid attitude information is unavailable because of a remote attitude-source, indicator-servo or power problem. The computer flag warns when steering-command information is invalid because of a flight-computer or command-drive fault. These warnings are operationally significant and must not be treated as cosmetic annunciations during inspection or troubleshooting.

System composition and signal flow

A representative signal path is remote attitude source → compatible flight-control computer → KCI 310 attitude and command-drive circuits → cockpit display. Navigation receivers, heading sources, altitude inputs and mode controls may provide information to the flight-control computer according to the particular installation. The computer converts selected modes and sensor inputs into pitch and roll steering commands, while the KCI 310 presents those commands together with attitude information for the pilot.

The exact companion units vary by approved system. BendixKing documentation shows the KCI 310 family in compatible KFC installations, but that does not make every KCI suffix interchangeable or prove eligibility for every aircraft fitted with a KFC system. Troubleshooting must consider the remote attitude source, flight-control computer, wiring, supply, connector, indicator mechanisms and system test functions. Related avionics are connected system components, not substitutes for this indicator.

Identification, installation and inspection

The photographed instrument carries the KCI 310 Flight Director designation and Part Number 066-3020-12. The original rear plate also identifies a weight of 4.3 lb and qualification references associated with the photographed unit. The front shows DIM and BRT controls, ATTITUDE and COMPUTER flags, a TEST control, bank references and the command presentation. These visible features support exact identification, but approved component data remains controlling for installation and maintenance.

Receiving inspection should compare the complete Part Number, serial and modification records, bezel, glass, horizon display, command cue, flags, controls, connector and mounting points. Functional testing should include valid attitude response, command-bar movement, flag operation, dimming, brightness, test response and correct communication with the installed flight-control equipment. Connector pin assignments, supply limits, lighting circuits and adjustment procedures must be taken from current approved maintenance and installation data for 066-3020-12.

Overhauled supply and ordering information

This 066-3020-12 KCI 310 is offered in Overhauled condition from partner stock with a six-month warranty. The quotation will identify the allocated serial number, overhaul or repair organization, release documentation, bench-test status and included accessories. A mating connector, mounting hardware, remote attitude source, flight computer and other system components are supplied only when expressly stated.

For an inquiry, specify Part Number 066-3020-12, model KCI 310, aircraft type, installed flight-control system, required certification, connector requirement and quantity. Related cockpit and navigation equipment can be reviewed in the Garmin / BendixKing / Honeywell / Collins category. Final eligibility, configuration and interchangeability must be established through the aircraft equipment list and approved system documentation.

Maintenance records should retain the complete suffix and modification status so that later replacement decisions are based on the exact configuration rather than a visually similar KCI 310 family unit.
