BendixKing KNI 416 indicator 066-3044-04

066-3044-04 is the exact Part Number for the BendixKing KNI 416 radar altitude indicator with a black faceplate and night-vision-goggle lighting. The cockpit instrument displays radar height above the terrain from 0 to 2,000 feet when connected to a compatible radar altimeter receiver-transmitter. Its nonlinear scale provides close spacing at higher values and increased visual resolution near the ground.

The KNI 416 is an indicator, not the radio-frequency measuring unit. It receives altitude and validity information from the compatible KRA 405 or KRA 405B radar altimeter chain. The pilot can set a decision-height reference with the front control, use the TEST function and monitor the warning flag. A correct indication depends on the receiver-transmitter, two antennas, coaxial cables, power, wiring and aircraft installation.

Altitude scale and cockpit indications

The displayed range is 0 to 2,000 feet above ground level. Aircraft documentation describes scale increments of 5 feet from 0 to 200 feet, 20 feet from 200 to 500 feet and 100 feet from 500 to 2,000 feet. This nonlinear presentation concentrates detail in the low-altitude region used during approach, hover and terrain-clearance monitoring. The orange pointer shows measured radar altitude.

A movable decision-height marker is set from the front knob. The yellow DH annunciator supports the associated warning function when the aircraft descends through the selected reference in a correctly wired system. A flag or invalid indication warns that reliable altitude information is not available or appears during the applicable test condition. Flight crews must interpret these indications under the approved aircraft procedures.

The 066-3044-04 suffix is specifically the black-faceplate NVG-lighted version. Standard 5-volt, 28-volt, gray-faceplate and other lighting variants have different suffixes and should not be substituted by appearance.

KRA 405B system relationship and accuracy

A typical signal path begins with two KA 54A radar-altimeter antennas. The KRA 405B receiver-transmitter sends a frequency-modulated continuous-wave signal and processes the returned energy to calculate height. Altitude and validity outputs are passed to the KNI 416, which converts the electrical information into pointer, flag and decision-height indications. Compatible flight-control or warning systems can also receive selected valid or trip outputs from the radar-altimeter installation.

Honeywell system data publish KNI 415 / KNI 416 indicator accuracy of plus or minus 4 feet or 4 percent, whichever is greater, from 0 to 500 feet, and plus or minus 5 percent from 500 to 2,500 feet. The complete KRA 405B system accuracy is specified separately. Indicator performance should not be confused with total installed-system accuracy, which also depends on the transceiver, antennas, coaxial paths and installation geometry.

Dimensions, environment and inspection

Published KNI 416 dimensions are approximately 6.69 inches long by 3.26 inches wide by 3.26 inches high. Approximate weight is 1.7 pounds. The documented operating-temperature range is -20 °C to +71 °C, with an operating altitude of 55,000 feet. Primary system power is based on a nominal 27.5 VDC installation, while this exact -04 indicator uses the specified NVG lighting configuration rather than a standard panel-lamp suffix.

The source catalog record for the photographed unit is explicitly titled 066-03044-0004 / 066-3044-04 and identifies the black NVG KNI 416 configuration. The available front-angle photograph does not show the rear identification plate, so the visible image cannot independently prove the suffix from a readable label. The allocated stock unit must still be confirmed from its own plate and commercial documentation.

Receiving inspection should verify Part Number 066-3044-04, model KNI 416, black faceplate, NVG lighting, pointer, scale, DH marker, flag, test control, rear connector, enclosure and release paperwork. Bench testing should check scale accuracy at the required test points, pointer movement, flag operation, decision-height output, lighting and electrical interface. Installed testing must include the complete receiver-transmitter and antenna chain.

Repairable supply and ordering information

This 066-3044-04 KNI 416 is offered in Repairable condition from partner stock with a six-month warranty under the quoted supply terms. Repairable means the unit requires approved evaluation or maintenance before return to service and must not be represented as ready for installation. The catalog images show the black NVG faceplate configuration; the complete suffix remains the controlling identification.

For an inquiry, specify Part Number 066-3044-04, model KNI 416, installed KRA 405 or KRA 405B configuration, aircraft type, lighting requirement, repair or exchange scope, release-document requirement and quantity. Related receiver-transmitters, indicators and antennas can be reviewed in the Garmin / BendixKing / Honeywell / Collins category. System association does not make different indicator suffixes interchangeable.
