Updating garmin 430 gps
Yes, the Bendix/King KPI-553A can display the distance information output from the Garmin GNS-430 BUT only with the use of the Garmin GAD-42 Adapter.
The KPI-553A uses King Serial Data/Clock for its distance information format.
This STC includes appendices detailing the approved equipment that can be interfaced to the WAAS capable units as well as approved installation diagrams for these interfaces.
The upgrade from Garmin includes the necessary updating of the unit, WAAS antenna, and new IFR-W Jeppesen database.
This output only provides VOR/ILS information on the indicator not GPS deviation information. Since the Garmin GPS 400 is the GPS only version of the GNS 430 GPS/Nav/Comm, it only contains the annunciators for message, waypoint, Auto (GPS AUTO mode of operation), OBS (GPS OBS mode of operation), terminal, approach, and integrity (for position error).
Since the GPS 400 does not contain the VOR/LOC/Glideslope portion of the GNS-430, the CDI source select button is omitted as well as the VLOC/GPS annunciator.
It is very important that pilots, aircraft owners and operators ensure installations are performed by skilled, experienced technical personnel to provide the safest flying environment and experience.
There are quite a few changes and issues that need to be addressed in reference to upgrading/modifying a GNS-400/500 series unit to include WAAS capability.
