Garmin GNS 430 GPS/NAV/COM Navigator

GNS 430 is a panel-mounted GPS/NAV/COM navigator without WAAS: 12-channel GPS for IFR en route, terminal and non-precision approach, a VHF COM of at least 10 W, and VOR, localizer and glideslope receivers. P/N 011-00280-10 takes 11–33 V DC (14 V and 28 V systems). A certified EU installation beyond CS-STAN limits needs an approved modification and a Certificate of Release to Service.

The LCD has 240 × 128 pixels in a 6.25 × 2.66 in (159 × 67 mm) bezel. The navigation and terrain databases load from two data cards in the front panel.
The 12-channel GPS receiver is listed to TSO-C129a for IFR en route, terminal and non-precision approach. LPV approaches need the WAAS GNS 430W.
The VHF COM tunes 118.000–136.975 MHz in 25 kHz steps and can be set to 8.33 kHz spacing (2,280 channels). Transmit power is at least 10 W.
VOR (108.00–117.95 MHz), localizer and glideslope receivers are built in. Interfaces are ARINC 429, RS-232, CDI/HSI, RMI, altitude input and fuel/air data.
P/N 011-00280-10 takes 11–33 V DC and runs on 14 V and 28 V systems. P/N 011-00280-00 and the GNS 430A are 28 V units.
The unit weighs 2.3 kg, or 2.9 kg installed with rack and connectors. Depth behind the panel is 279 mm; operating range is −20 to +55 °C.

Front panel and pages

The COM and VLOC windows at the left of the display each show an active and a standby frequency with a flip-flop key; pressing and holding the COM flip-flop key selects 121.500 MHz. The right-hand knobs select the page group (NAV, WPT, AUX or NRST) and the page within it, and holding CLR returns to the default NAV page.

The NAV group has seven pages: default NAV, map, TERRAIN, NAV/COM, position, satellite status and vertical navigation. The bottom row holds the CDI, OBS, MSG, FPL and PROC keys.

Flight plans, approaches and CDI scale

The unit stores up to 20 flight plans of up to 31 waypoints each, and up to nine checklists of up to 30 entries. Approaches come from the NavData card and are selected with the PROC key; Direct-To and OBS mode have their own keys.

The CDI scale follows the phase of flight: 5.0 nm full scale en route, 1.0 nm in terminal mode within 30 nm of the destination, and 0.3 nm in approach mode within 2.0 nm of the final approach fix.

Interfaces and connected equipment

ARINC 429 output runs in four configurations (ARINC 429, GAMA 429, GAMA 429 Graphics and GAMA 429 Graphics with Int), and RS-232 output in two formats (Type 1, ARNAV, and Type 2, Northstar). Altitude and fuel/air data come in over a serial input (Icarus, Shadin or Rosetta formats) or as Gillham code.

With a traffic or weather source connected, the NAV group grows to eight or nine pages. Garmin notes that the lateral and vertical deviation outputs of the main board carry 120 ms of internal transport delay and suit only applications where that delay has been evaluated.

Databases, data cards and TERRAIN

The Jeppesen NavData card goes in the left card slot and the terrain card in the right-most slot. Garmin lists data cards for Worldwide, Americas and International coverage and terrain cards of 128 MB and 256 MB; the 256 MB card needs main software 5.02 or later. Database updates are released every 28 days.

The TERRAIN page needs the terrain card. Garmin states that TERRAIN is an aid to awareness and not a certified terrain awareness system, and that the basemap is not for navigation.

Part numbers and kit contents

P/N 011-00280-10 is the black unit for 14 V and 28 V; 011-00280-30 is the gray version and 011-00280-00 the black 28 V-only unit. Garmin catalog number 010-00139-10 is the unit without accessories, and 010-00139-11 the unit with mounting rack 115-00243-00, connector kit 011-00351-00, back plate assembly 011-00676-00 and product information kit K00-00055-00.

The GNS 430A (011-00836-xx, 28 V, 16 W COM) and the GNS 430W (011-01060-40) and 430AW (011-01061-40) WAAS upgrade units are separate products. Serviceable/overhauled units and repairs are offered for P/N 011-00280-10.

EASA path and installation limits

EASA FAQ 46836 (last updated May 2018) states that the COM, NAV and GPS functions of Garmin GNS devices can be eligible for CS-STAN through CS-SC052b with CS-SC001 and CS-SC056. The limits of CS-SC052b apply: any connection to an autopilot is not permitted, because that goes beyond situational-awareness use.

Beyond those limits a certified EU installation needs an approved modification for the aircraft type and a Certificate of Release to Service. Garmin's initial certification was an FAA STC on a Piper PA32; STC SA00705WI (GNS 430 and 430A) is an FAA approval, not an EASA one. Fit depends on the P/N and the aircraft type.

What separates the GNS 430, GNS 430A and GNS 430W?

The GNS 430A is the 28 V version with a COM transmitter of at least 16 W; the GNS 430 has at least 10 W. Garmin's maintenance manual lists the GNS 430W (011-01060-40) and GNS 430AW (011-01061-40) as WAAS upgrades of the non-WAAS unit, and LPV approaches need a WAAS unit.

The GNS 430 with P/N 011-00280-10 is the non-WAAS 10 W unit for 14 V and 28 V.

Is the GNS 430 ETSO-approved?

Garmin's installation manual lists TSO-C129a for the GPS function. The COM transceiver is listed to TSO-C37d and TSO-C38d, and the VOR, localizer and glideslope receivers to TSO-C40c, TSO-C36e and TSO-C34e.

For the GNS 430 the manual names JTSO designations for the COM and NAV functions; ETSO designations are named for the GNS 430A. The approval of an installation follows the approved modification.

Can a GNS 430 drive a G500 or G600 display?

Garmin's G500/G600 installation manual names the GTN 6XX/7XX, the 400W/500W series and the GNS 480 as the approved GPS/SBAS navigators, with at least one required per system. The non-WAAS GNS 430 is not on that list; the WAAS GNS 430W is.

What does the installation need besides the unit?

Garmin lists a COM antenna, a VOR/LOC antenna, a glideslope antenna (or a low-loss splitter with the VOR/LOC antenna), headphones and a microphone as required but not provided. The GPS antenna must be one that Garmin lists, such as the GA 56, or meet Garmin's requirements.

The minimum installation also needs a pressure altitude device, a manual course device for the VOR receiver and a TSO-approved HSI/CDI indicator or EFIS. Fit depends on the P/N and the aircraft type.

What current does it draw and does it need cooling?

Garmin lists 1.5 A maximum at 27.5 V on the main connector. On the COM connector the 11–33 V versions draw 3.0 A at 27.5 V or 6.0 A at 13.75 V while transmitting.

The unit meets the TSO requirements without external cooling. Garmin recommends an electric fan with 1 CFM at 0.1 in of water, because a lower temperature extends service life, and warns against cooling with outside forced air.

What maintenance does the unit need?

A built-in 3 V lithium battery keeps user waypoints and settings in memory. Its life is up to 5 years, and the Memory Battery Low message calls for replacement. Replacing it can erase user data (message Stored Data Lost), and the unit then needs 20–30 minutes on an antenna to collect almanac data.

The screen has an anti-reflective coating: a lint-free cloth and an eyeglass cleaner that is safe for such coatings, never ammonia. Garmin's installation manual lists hardware mod levels 1 to 7 with their service bulletins.

What does INT mean in the Garmin GNS 430 and GNS 530 model names?

INT refers to the International models.

Models without INT are meant for use in the USA with a 110 V power supply. INT models have a 220 V power supply.

Which indicators are compatible with the Garmin GNS 430 and GNS 530 series?

According to the Installation Manual, the following indicators are compatible with the main switchable VOR/ILS/GPS indicator output (connector P4001) of the Garmin GNS 430 and GNS 530 GPS/Nav/Comms:

Garmin GI-102 (no longer available), GI-102A, GI-106 (no longer available), GI-106A; S-Tec ST-180 HSI; King KI-202, KI-206, KI-208A, KI-209A, KI-525A, KPI-552, KPI-552B, KPI-553, KPI-553A, KPI-553B
Collins 331A-3G HSI, 331A-9G HSI, 331A-6P HSI; Bendix IN-831A; Century NSD-360, NSD-360A, NSD-1000 HSI; Sperry/Honeywell RD-550A, 650 HSI

The following indicators are compatible as well, but are not mentioned in the installation manual: King KNI-520, Collins/S-Tec IND-350, IND-350A, IND-351, IND-351A, 331H-3G. A non-converter type indicator is required for the VOR/ILS/GPS indicator interface to the GNS 430/530.

Note: King KI-203, KI-204, KI-208 and KI-209 may be connected to the secondary VOR/ILS output of the GNS 430/530 (connector P4006). This output provides only VOR/ILS information on the indicator, not GPS deviation information.

Does the Garmin GNS 430/530 need to be configured before use?

Garmin GNS 400/500 series units require setup and configuration before they function properly and can be used.

The system does not use a configuration module. A configuration module would allow easy removal and replacement of units while keeping the programmed configuration information.

If you exchange units in an aircraft, you must have a record of the configuration parameters to reprogram into the replacement unit.

What items are needed to install the GNS 430/430W/530/530W into my aircraft?

To use all functions of the GNS 430/430W/530/530W, the following items are required:

GPS antenna (usually included when the system is purchased)
External CDI* for VOR/ILS navigation and glideslope information; also required for IFR certification
Nav antenna* for VHF Nav functions
COMM antenna* for COMM functions

*These items are not included with the standard GNS system. Existing aircraft units may be interfaced, but the GNS installation manual should be consulted for complete compatibility information. As with all avionics installations, other general materials are required but not supplied with the standard system. These can include, but are not limited to, wire, mounting screws, circuit breakers, tie wraps, ring terminals, coaxial cable, hand crimping tools, and crimp positioner/insertion/extraction tools.

Which traffic systems interface with and display on the Garmin GNS 430/530 series?

The GNS 430/530 series units can accept information from any traffic advisory system with ARINC 429 transmit formats.

Can original Garmin GNS 400/500 series units be upgraded to HTAWS?

Garmin HTAWS (Helicopter Terrain Awareness) is only available for Garmin WAAS GPS receivers.

The added GPS integrity, quality and performance of WAAS GPS is needed for the helicopter terrain functions.

An original GNS 430, GNC 420, GPS 400, GNS 530 or GPS 500 navigator must therefore be upgraded to WAAS ("W" status) before HTAWS can be incorporated.

Can the Garmin GNS 430/530 and GNS 430W/530W be upgraded to the A version?

No. Garmin does not offer an upgrade to add the 16 watt comm (the "A" version) to the GNS 430/530 and GNS 430W/530W units.

Can the Garmin GTN 650 replace a GNS 430 by sliding it into the existing GNS 430 tray?

No. The GTN 650 is not a slide-in replacement for the GNS 430, and the tray is not the same.

Does the Garmin GNC 255 NAV/COM interface with a non-WAAS GNS 430?

The GNS 430 is a GPS/NAV/COM. The GNC 255 is a NAV/COM.

The two units do not need to be tied together. Both can connect to an audio panel to provide a dual NAV/COM system.
