Section 1 - General
The airplane is equipped with a Garmin GNS 430 GPS Navigator with
VHF Nav, ILS, and VHF Com herein referred to as the “Navigator.” The
GNS 430 is capable of providing IFR enroute, terminal, and approach
navigation with position accuracies better than 15 meters. The system
utilizes the Global Positioning System (GPS) satellite network to derive
the airplane’s position (latitude, longitude, and altitude) and the
altitude digitizer to enhance the altitude calculation.
The GARMIN GNS 430 GPS Navigator may be installed in single or
dual installations. If one GNS 430 is installed, it will be designated
‘GPS 1,’ and either a GARMIN GNC 250XLGPS Navigator or a
GARMIN GNC 420 GPS Navigator will be installed as GPS 2. Refer to
applicable supplements for descriptions of these units.
If two GARMIN GNS 430 Navigators are installed, the upper unit will
be designated ‘GPS 1’ and the lower unit will be designated ‘GPS 2.’ In
these installations, the MFD and the HSI will display GPS 1
information and the CDI (VOR/LOC/ILS/GS Indicator) will display GPS
2 information.
