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. 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 KT74. 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 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.
