must match that set in the TT31. According to the Trig TT31 installation manual, RS232 In 1 (on the
primary connector) is typically used to receive this data.
Sandia
Note: All steps in the “Safe-Fly/SPC Configuration” section above must be completed before the
following settings are made.
Testing is underway to validate the use of the Safe-Fly GPS with the Sandia ADS-B out devices. This
manual will be updated when GRT Avionics and Sandia and approved the use of this GPS. We expect
this approval soon (second quarter 2017 or sooner).
Uavionix
Note: All steps in the “Safe-Fly/SPC Configuration” section above must be completed before the
following settings are made.
Use of the Safe-Fly GPS for the uAvionix EchoUAT is approved for experimental category airplanes by
GRT Avionics when installed and configured as described in this section. This installation meets the
requirements of FAR 91-227(c).
Operation without EFIS Control (Also Legacy Horizon WS and HS models)
When the Safe-Fly and EchoUAT are ordered together with the pre-wired cable, no connection to an
EFIS is required. Mounting the Safe-Fly/EchoUAT, connecting the antennas, and supplying power via
the cable is sufficient to provide UAT out, meet all 2020 compliance, and provide ADS-B weather and
traffic data via Wi-Fi to a tablet.
However, the EchoUAT must be configured as described in the
“EchoUAT Settings” section below before the EchoUAT will function as an ADS-B out device
and the
connection from pin 1 on the Safe-Fly GPS to pin 6 on the Echo UAT must be made
. This wire is
included in the harness but not connected to pin 6 of the Safe-Fly GPS, as shown in the section “Error:
Reference source not found” belo..
Optional connections that allows the GRT EFIS to use the GPS position data, ADS-B weather and
traffic, and the serial port combiner features for additional serial ports are also described. These
connections also provide the EchoUAT with pressure altitude data from the EFIS (if available).
