6.7 GAD 42
The AeroNav XXX can be connected to the Garmin GAD42 Interface Adapter.
If the AeroNav XXX is replacing a GNS530/W or GNS430/W that had previously been connected to a
GAD42, then no action is required since the configuration is already saved in the GAD42.
If this is a new installation of an AeroNav XXX (i.e. not replacing an existing GNS-530/W or GNS-
430/W) or if the GAD42 had to be replaced for service, then the GAD42 must be configured via a
manual strapping method as described in Garmin P/N 190-00159-00 GAD42 Installation Manual,
Section 5.1.
6.8 Air Data System Sources
The AeroNav XXX can be connected to either Uncorrected or Baro-corrected Altitude Sources. The
AeroNav XXX can be connected to the following Air Data Systems:

Table 69 Air Data Systems
6.8.1.1 Uncorrected Pressure Altitude Sources
The AeroNav XXX can accept uncorrected altitude from multiple sources in the following formats:
ARINC 429, RS232, or a Gray Code altitude encoder. If multiple altitude sources are connected, the
AeroNav XXX will use the altitude sources in this order (highest first):
1. ARINC 429 ADC
2. ARINC 429 EFIS
3. ARINC 429 Traffic Advisory System
4. RS232 FADC
5. RS-232 Altitude Encoder
6. Parallel Altitude Encoder (Gray Code)
6.8.1.2 Baro-corrected Altitude Sources
The AeroNav XXX can accept baro-corrected altitude from multiple sources. The AeroNav XXX can
accept Altitude information from altitude Air Data Systems in the following formats: ARINC 429 or
RS232. If multiple altitude sources are connected to the AeroNav XXX, the AeroNav XXX will use the
altitude sources in this order (highest first):
1. ARINC 429 INS/IRU
2. ARINC 429 EFIS
3. ARINC from Transponder
4. RS232 FADC
