Navigation (Nav) Receiver

Serials with Avionics Configuration A - 0002 through 1601, 1603
through 1643 and 1645 through 1662 without PFD:
The airplane is equipped with one NAV receiver integrated into the
Garmin GNS 430 GPS Navigators (the GNS 420 does not incorporate
a NAV receiver). Mounted in the upper radio rack slot, this unit is
designated NAV 1. The GNS 430 has VHF Omnirange/Localizer
(VOR/LOC) capability. The VOR/LOC receiver receives VOR/LOC on
a frequency range from 108.000 Mhz to 117.950 Mhz with 50 kHz
spacing. The GNS 430 has glideslope capability. Glideslope is
received from 329.150 to 335.000 in 150 kHz steps. The receivers and
integrated controls are mounted in the Garmin GNS 430 control
display. The receiver controls provide 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, mounted on top of the vertical tail,
provides VOR/LOC input for both Nav receivers.
NAV 1 – The upper GARMIN GNS 430 is designated NAV 1. 28 VDC
for navigation receiver operation is controlled through the Avionics
Master Switch on the bolster switch panel and supplied through the 5-
amp GPS1 circuit breaker on the Avionics Essential Bus row.

The airplane is equipped with two NAV receivers integrated into the
Garmin GNS 430 GPS Navigators. The upper unit is designated NAV
1 and the lower unit is designated NAV 2. The Nav receiver controls
are integrated into the Garmin GNS control mounted in the center
console. Each unit has VHF Omnirange/Localizer (VOR/LOC)
capability. The VOR/LOC receiver receives VOR/LOC on a frequency
range from 108.000 Mhz to 117.950 Mhz with 50 kHz spacing. The
GNS 430 has glideslope capability. Glideslope is received from
329.150 to 335.000 in 150 kHz steps. 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, mounted
