BendixKing KAS 297C selector 065-0089-04

065-0089-04 is the exact BendixKing Part Number for this KAS 297C altitude and vertical-speed selector. The panel gives the crew a dedicated interface for entering a selected altitude and, when supported by the installed flight-control system, a desired climb or descent rate. It is a selector and display unit rather than a stand-alone air-data computer or autopilot.

The full -04 suffix must remain part of the identification. Other KAS 297C versions can share the same front-panel appearance while differing in internal configuration or modification status. Maintenance and purchasing decisions should be based on the aircraft equipment list and Part Number 065-0089-04, not on the model name alone.

Altitude and vertical-speed selection

The SET control is used to change the displayed selection. The ENG and ARM controls support engagement and arming logic in an approved installation, while the PULL VS function changes the selector to the vertical-speed entry mode where applicable. The display provides the crew with a clear numeric reference for the value being selected.

Official BendixKing KFC 275/325 documentation lists the KAS 297C as the altitude/vertical-speed preselector used with that flight-control family. During an altitude capture sequence, the preselector works with the flight computer and compatible air-data source. The flight computer, not the KAS 297C alone, generates the aircraft control command and drives the appropriate servo.

Electrical and plate data for the -04 unit

The exact photographed identification plate states 14 VDC at 0.4 A or 28 VDC at 0.2 A. It gives a weight of 1.2 lb, approximately 0.54 kg, and carries TSO C9c, TSO C52a and RTCA/DO-160B references. These figures are taken from the plate of 065-0089-04 and are not transferred from another KAS 297C suffix.

The photographed serial number is 1910. The rear view also shows the original multipin connector and modification-status marks. Connector pin assignments, allowable wiring, circuit protection and display-lighting requirements must still be checked in the installation data. A visible connector does not establish pin compatibility with another version.

System integration and installation checks

A simplified control chain is pilot entry at KAS 297C → altitude or vertical-speed selection supplied to the compatible flight-control system → processing by the flight computer using air-data and attitude inputs → command to the approved servo actuator. The KMC 321 mode controller and KCP 220 flight computer are associated units in documented KFC 275/325 configurations, but their inclusion depends on the aircraft installation.

Before installation, technicians should confirm the complete suffix, connector keying, mounting dimensions, display configuration, power supply, aircraft wiring and approved system version. A functional check should verify selection, arming, engagement, display response and altitude-capture behavior in accordance with the aircraft flight-manual supplement and maintenance data. No universal aircraft applicability is claimed for this suffix.

Selection and indication faults can also originate in the air-data source, mode controller, flight computer, wiring or display-lighting circuit. Bench replacement should therefore follow documented fault isolation. The selector should be evaluated together with the system symptoms rather than treated as the only possible cause.
