    2.2.3 IFR VOR/LOC/GS Installation The minimum GNS 430W installation requires the following items for an IFR VOR/LOC/GS Installation: GNS 430W (installed in the aircraft manufacturer approved location) GPS antenna, VOR/LOC antenna, glideslope antenna, and COM antenna. An External CDI/HSI indicator must be installed in the pilot‘s primary field-of-view (or in the aircraft manufacturer approved mounting location).

  • Page 37: Multiple Baro-Corrected Altitude Sources

    2.3.2 Multiple Baro-Corrected Altitude Sources The 400W Series can accept baro-corrected altitude from an ARINC 429 ADC, ARINC 429 EFIS, RS-232 FADC, and GTX 33/330 transponder. If multiple sources of baro-corrected altitude data are supplied to the 400W Series unit, only valid data from the highest priority source is used.

  • Page 38: Antenna Considerations

    This section contains mounting location considerations for the antennas required for the 400W Series units. The GPS 400W requires a GPS/WAAS antenna, the GNC 420W/420AW requires a GPS/WAAS and COM antenna, and the GNS 430W and GNS 430AW require four antennas: a GPS/WAAS antenna, a COM antenna, a NAV antenna, and a Glideslope antenna.

  • Page 41: Vor/Loc Antenna Location

    Locate the 400W Series unit as far as possible from all COM antennas. If a COM antenna is found to be the problem, a 1.57542 GHz notch filter (Garmin P/N 330-00067-00) may be installed in the VHF COM coax, as close to the COM as possible. This filter is not required for the GNC 420W and GNS 430W transmitters.

  • Page 42: Mounting Considerations

    Mounting Considerations The 400W Series unit is designed to mount in the avionics stack in the aircraft instrument panel within view and reach of the pilot. The primary unit location should minimize pilot head movement when transitioning between looking outside of the cockpit and viewing/operating the 400W Series unit. The location should be such that the 400W Series unit is not blocked by the glare shield on top, or by the throttles, control yoke, etc.
