Integrated GPS, VHF communication and VLOC functions

The GNS 430 integrates a 12-channel GPS receiver with a 16-color active-matrix display and moving-map presentation. Its navigation pages support direct-to navigation, stored flight plans, airport and navigation-aid information, and IFR procedures contained in the installed navigation database. Course-deviation and compatible roll-steering outputs allow the unit to work with approved aircraft indicators and flight-guidance equipment when the installation is configured accordingly.

The communication section covers the civil aviation VHF COM band from 118.000 to 136.975 MHz. Garmin documentation identifies 760-channel operation with 25 kHz spacing and a software-configurable 2,280-channel option with 8.33 kHz spacing for applicable installations. The standard GNS 430 provides a 10-watt minimum transmitter. VLOC functions include VOR, localizer and glideslope reception, allowing the unit to combine radio navigation and communication controls with GPS information on the same front panel.

Display, controls and cockpit operation

The front panel uses dedicated frequency controls, concentric selector knobs and clearly separated navigation keys. Active and standby COM and VLOC frequencies are shown beside the map and navigation area. The CDI, OBS, MSG, FPL and PROC keys give direct access to course selection, messages, flight plans and procedures, while the range, menu, clear, enter and direct-to controls support map and navigation management.

Garmin specifies a color LCD with an approximate visible area of 2 by 3 inches and a resolution of 128 by 240 pixels for the legacy GNS 430. The compact panel format is designed to combine functions that might otherwise require separate navigation and communication units. Actual use, database loading and operational approval remain dependent on the aircraft installation, current data, software configuration and the applicable flight-manual supplement.

Installation dimensions, power and interfaces

The installed unit dimensions are approximately 6.25 inches wide, 2.65 inches high and 11.00 inches deep behind the instrument panel with connectors. Installed weight is approximately 6.6 lb, or 3.0 kg. The GNS 430 family supports 14- and 28-volt aircraft installations. Garmin installation information for MPN 011-00280-10 specifically identifies an 11–33 V DC COM power input, allowing the unit to be installed in 14-volt aircraft without an external voltage converter when the installation follows approved data.

Published interfaces include RS-232 and RS-422 serial connections, ARINC 429 digital output and compatible course-deviation, altitude and fuel-data connections. These interfaces describe available equipment capabilities, not a promise that every external device is approved with every aircraft. Installation must be performed using the applicable Garmin installation manual, approved wiring data and aircraft-specific authorization.

Condition, documentation and ordering

This 011-00280-10 position is listed as repaired and available from partner stock with a six-month warranty. Dual EASA/FAA release documentation is indicated for the offered position and should be reconfirmed for the exact serial number before shipment. The expected Aviamisto delivery time is 14–20 days. Included accessories are not assumed from the historical Garmin standard package; the rack, connectors, antenna, data card, manuals and other items must be confirmed during quotation.

To order, provide the exact MPN 011-00280-10, the GNS 430 model name, required quantity, destination and any certification or traceability requirements. Confirm that a non-WAAS GNS 430 is required and compare the offered configuration with the aircraft records. Other Garmin, BendixKing and Honeywell products are available in the Garmin / BendixKing / Honeywell category, but related category placement does not indicate interchangeability.
