powered by 28 VDC through the 5-amp GPS1 circuit breaker on the
Avionics Essential Bus.
The Jeppesen Navigation Database provides access to data on
Airports, Approaches, Standard Instrument Departures (SIDs),
Standard Terminal Arrivals (STARs), VORs, NDBs, Intersections,
Minimum Safe Altitudes, Controlled Airspace Advisories and
Frequencies. North American and International databases are
available. Database information is provided on a card that can be
inserted into the card slot on the GPS unit. Subscription information is
provided in a subscription packet provided with each system.
Navigation (Nav) Receiver
The Garmin GNS 430 provides an integrated Navigation (NAV)
receiver with VHF Omnirange/Localizer (VOR/LOC) and Glideslope
(G/S) capability. The VOR/LOC receiver receives on a frequency
range from 108.000 Mhz to 117.950 Mhz with 50 kHz spacing.
Glideslope is received from 329.150 to 335.00 in 150 kHz steps. The
Nav receiver controls are integrated into the Garmin GNS 430 control
mounted in the center console. The receiver control provides active
and standby frequency indication, frequency memory storage, and
knob-operated frequency selection. IDENT audio output for VOR and
LOC is provided to the audio system. The Nav antenna is mounted on
top of the vertical tail. 28 VDC for navigation receiver operation is
controlled through the Avionics Master Switch on the bolster switch
panel and supplied through the 5-amp GPS 1 circuit breaker on the
Avionics Essential Bus. The airplane is equipped with a Garmin GNS
430 integrated GPS Navigator, Navigation (NAV) receiver with VHF
Omnirange/Localizer (VOR/LOC) and Glideslope receiver.
Communication (COM) Transceiver
The
GNS
430
includes
a
digitally-tuned
integrated
VHF
communications (COM) transceiver. The transceiver and integrated
controls are mounted in the Garmin GNS 430 unit. The transceiver
receives all narrow- and wide-band VHF communication transmissions
transmitted within a frequency range of 118.000 MHz to 136.975 MHz
in 25.0 kHz steps (720 channels). For European operations, the COM
can be operator configured for 8.33 kHz channel spacing (2280
channels). The tuning controls are collocated with the NAV at the left
