Safe-Fly with EchoUAT Post-Installation Checkout Procedure
The following post-installation checkout procedure should be used to validate normal operation of this
equipment after installation. This procedure requires that power is supplied to the equipment.
1. Using the Echo app, select “Monitor” at the top of the app. This will show the Address, call
sign, and other data, including Latitude and Longitude. Verify the Latitude and Longitude fields
are not dashes (actual latitude and longitude should be displayed. This confirms the EchoUAT is
communicating successfully with the Safe-Fly.
2. Refer to the “Status Reporting” section above to verify serial communication is functioning
between the EFIS and Safefly control input/output, power connections, and Safe-Fly software
version.
3. If ADS-B data is provided to the EFIS via a serial connection, verify the serial data counter is
counting on the Set Menu, General setup, for the serial port used to receive this data. When in
flight, reception of ADS-B data can be verified on the Set Menu, Display Unit Maintenance,
under the ADS-B status setting. Valid frame should be detected. Alternatively, when in-flight
and in range of an ADS-B ground station, METARs data will be observed when reviewing
airport details.
4. If the Safe-Fly is connected to the EFIS, detailed data about the performance of the GPS,
including the number of satellites being tracked, the signal strengths, etc., is available on the Set
Menu, Display Unit, GPS Status. If more than one GPS is connected to the EFIS, be sure to
select this GPS. Other than the first few minutes after power-up, RAIM integrity should be
provided and at least 6 satellites should be used in the calculations. If this is not observed, check
the antenna connection and verify the antenna has a clear view of the sky.
5. An FAA Performance report should be requested. See “Verifying operation via the FAA
Performance Report Request” section below.
