BendixKing KPI 553A indicator 066-3045-50

066-3045-50 is the exact Part Number of this BendixKing KPI 553A pictorial navigation indicator. The panel instrument combines heading and selected-course information with lateral navigation deviation, glideslope guidance, source flags and command-related references used by an approved aircraft navigation and automatic-flight-control installation. Its integrated presentation allows the crew to compare aircraft heading, desired course and deviation without reading several separate instruments.

The KPI 553A is an indicator, not an independent navigation receiver, heading sensor or autopilot computer. It depends on compatible heading, VOR/localizer, glideslope and aircraft-system interfaces. The complete -50 suffix must be retained in purchasing and maintenance records because similar KPI 553 and KPI 553A faces may use different internal interfaces, lighting, connector details or modification status. Eligibility must be checked against the installed data plate and approved aircraft documentation.

Pictorial course and deviation presentation

The compass presentation supplies a heading reference when driven by the associated directional-gyro or compass equipment. Course-selection and deviation elements present the relationship between the selected path and the navigation signal. During a valid VOR or localizer operation, lateral displacement is shown relative to the selected course or approach centerline. Compatible glideslope input adds vertical-guidance information for an approved approach installation.

Warning flags identify unavailable or invalid guidance channels. A centered indication is meaningful only when the connected receivers, sensors, switching, wiring and validity logic are operating correctly. The instrument does not calculate aircraft position or generate radio signals. Its function is to display the information supplied by the aircraft system in a coordinated format and, where approved, provide related signals to the automatic-flight-control equipment.

KFC 300 system relationship

Honeywell service documentation identifies the KPI 553/A as a pictorial navigation indicator associated with the KFC 300 autopilot system family. A representative navigation chain is antenna → compatible VOR/localizer/glideslope receiver → deviation and validity signals → KPI 553A display. A representative heading chain is magnetic-reference equipment → directional gyro or heading system → indicator compass presentation. The installed arrangement can also include a flight computer, flight-command indicator and autopilot interfaces.

These related components form a system but are not interchangeable with the KPI 553A. Their exact models and Part Numbers depend on the aircraft configuration. The presence of a KFC 300 component elsewhere in an aircraft does not by itself prove that 066-3045-50 is approved for that installation. The equipment list, wiring diagram, modification record and applicable supplemental approval remain controlling.

Identification and technical inspection

The authentic rear photograph shows a Bendix/King KPI 553A pictorial navigation indicator and the exact 066-3045-50 identification. It also shows the long rectangular housing, mounting flange, two protected rear connection areas, modification marks and warning labels. These physical details help distinguish the offered configuration from another KPI 553-family unit that may have a similar front display.

Receiving inspection should compare the full Part Number, model, serial and modification marks, bezel, glass, compass card, course and deviation presentations, flags, controls, housing, connectors and mounting points. Bench testing should verify card movement, course selection, lateral and vertical deviation, validity flags, lighting and each approved interface. Electrical signals and connector pins must be taken from current KPI 553A maintenance data rather than inferred from another suffix.

Overhauled supply and ordering information

This 066-3045-50 KPI 553A is offered in Overhauled condition from partner stock with a six-month warranty. The quotation will identify the allocated serial number, overhaul organization, release documentation, bench-test status and accessories included with that unit. A mating connector, mounting hardware, navigation receiver, heading equipment and autopilot components are supplied only when expressly stated.

For an inquiry, specify Part Number 066-3045-50, model KPI 553A, aircraft type, installed autopilot and navigation configuration, electrical and lighting requirements, certification and quantity. Related products can be reviewed in the Garmin / BendixKing / Honeywell / Collins category. Final installation approval and interchangeability must be established from approved aircraft and system documentation.

Retaining the full suffix and modification record helps prevent substitution of a visually similar indicator with different electrical characteristics.
