BendixKing KNI 415 indicator 066-3031-01

066-3031-01 is the exact Part Number for this BendixKing KNI 415 radar altimeter indicator. The cockpit instrument displays radio-height information received from a compatible radar-altimeter system and gives the crew a manually adjustable decision-height reference. Its expanded circular scale is marked RADAR ALT X 100 FEET, allowing the pilot to read height above the reflecting surface according to the limits and procedures of the installed system.

The KNI 415 is an indicator, not a complete radio altimeter. It does not independently transmit a radar signal or calculate height without the associated transmitter/receiver, antennas, cabling and aircraft interfaces. The full -01 suffix is required because instruments with similar KNI model names may differ in lighting, voltage, bezel or system configuration. Part Number 066-3031-01 must be checked against the aircraft equipment list and approved installation data.

Height scale and decision-height function

The face presents an expanded scale from the low-height region through a maximum marked value of 25 hundreds of feet, or 2,500 ft. The non-linear arrangement provides more angular space where close-to-ground height changes require clear interpretation. A movable reference pointer is positioned with the lower-right control. The yellow DH pushbutton and associated annunciation support decision-height use according to the installed radar-altimeter system and aircraft procedures.

Radio height is geometric distance above the terrain or other reflecting surface beneath the aircraft; it is not barometric altitude above mean sea level. Displayed information can be affected by installation geometry, terrain, bank angle, system condition and operational limits. The crew must use the indication only within the approved flight manual and system limitations. A red warning sector or flag on the face helps show invalid or out-of-range conditions according to the system design.

Radar-altimeter system composition

A representative signal path is transmitting antenna → terrain reflection → receiving antenna → compatible radar-altimeter transmitter/receiver → height signal → KNI 415 cockpit indication. The decision-height control adds a selected reference used for crew alerting. Exact transmitter/receiver and antenna Part Numbers depend on the approved installation; they are not identified merely by the indicator bezel and must be verified in the aircraft wiring diagram and equipment records.

Honeywell’s official configuration catalog identifies the long-form 066-03031-0001 as a KNI 415 28-volt black indicator. That catalog form corresponds to the short commercial Part Number 066-3031-01 used for this product listing. The catalog also references a KNI 415/416 installation kit separately, confirming that installation hardware is not automatically part of the indicator supply.

Installation checks and repair assessment

Receiving inspection should compare the complete Part Number, model, serial information, bezel, scale, pointers, DH control, TEST control, mounting points and connector condition. Bench evaluation should confirm pointer movement, valid and invalid indication, decision-height adjustment, annunciation, lighting and response to the correct simulator or radar-altimeter test set. Testing must follow approved procedures and avoid applying signals or supply voltages based only on appearance.

This listing is in Repairable condition. Repair assessment may include inspection of the meter movement, bearings, lighting, warning flag, adjustment mechanism, electronics, connector and calibration. The final quotation should identify whether the unit is offered as-is for repair, evaluated with a known fault or accompanied by any test findings. A repairable unit should not be represented as airworthy or installed until properly repaired, tested, released and approved for the receiving aircraft.

Ordering and configuration control

This 066-3031-01 KNI 415 is supplied from partner stock with a six-month warranty under the stated repairable supply terms. The allocated serial number, repair scope, release status and accessories will be confirmed in the quotation. A transmitter/receiver, antennas, wiring, installation kit and mounting hardware are included only when expressly listed.

For an inquiry, specify Part Number 066-3031-01, model KNI 415, aircraft type, installed radar-altimeter system, voltage and lighting configuration, certification requirement and quantity. Related avionics can be reviewed in the Garmin / BendixKing / Honeywell / Collins category. Final eligibility must be confirmed against the approved aircraft data and the complete component suffix.

The short and long Part Number formats should both be retained in maintenance searches, while the physical data plate and approved records remain the controlling identification references.
