service. The AeroNav XXX will use the airdata source with
the highest priority, reference Section 6.8.1.1. Installers
must ensure the airdata source being used for transponder
Mode C transmissions complies with 14 CFR 91.217. After
installation, the transponder system must be tested per 14
CFR 91.411 to verify the airdata retransmitted by AeroNav
XXX is operating correctly prior to return to service.
The Hardware and Software Design Assurance for the
Altitude Retransmission is Level B and C respectively.
The AeroNav XXX has a maximum internal latency of 340
mS for retransmission the altitude data.

The AeroNav AML STC SA00343BO approves ADS-B out
capability for this ADS-B OUT transmitter and GNSS
position sensor combination to comply with 91.227.
•
For ADS-B out compliance, a squat switch is required for
automatically selecting the transponder air or ground
mode of operation. For aircraft without a squat switch,
connect the squat switch input of the transponder to
P1001 pin 8 of one of the AeroNav XXX for AeroNav’s with
software 10.0.0 or higher. Set the transponder to accept
an active low when performing that squat switch setup.

The AeroNav XXX retransmits the Altitude data received
from external altitude devices to GTX3X5. This is a non-
TSO function of the AeroNav XXX and must be tested and
approved by the installer prior to returning the aircraft to
service. The AeroNav XXX will use the airdata source with
the highest priority, reference Section 6.8.1.1. Installers

This system utilizes an internal position source for ADS-B
out compliance. See L3 STC.
