If you get SIL, SDA and NIC errors on your PAPR it is likely that the GRT is not set up properly. Make sure these values are entered in the GRT under General settings/TT22/echoUAT:   GRT EFIS TT22/EchoUAT Settings: DU-SF Communication (Status) Verify “Yes” SF-echoUAT Communication Verify “OK” Remote Status Verify “OK” External GPS Communication [...]

Connecting tailBeaconX to an MGL EFIS system

To communicate with MGL EFIS systems, the baud rate will have to be changed on the tailBeaconX to accommodate the 9600 baud rate that MGL systems use for the STX-165 transponder protocol. By default MGL sets the baud rate for this protocol at 9600, while tailBeaconX defaults at a baud rate of 2400. **To perform [...]

I am not seeing my flights on FlightAware or Flightradar24 or there are only partial sections of the flight displayed

Flightradar24 and FlightAware are predominately 1090mhz reporting sites. They get their flight data from their own network of 1090 receivers, not from the FAA. The skyBeacon, tailBeacon, and the echoUAT are all on the 978mhz (UAT) frequency. They are working on getting more stations with 978mhz reporting but it will be pretty hit and miss [...]

Sentry CO alarm testing

If your Sentry is exhibiting CO alarms when you think they are not warranted you can test it in an office, home, or car to see if it still behaves similarly. If it is going into an alarm or caution status, please contact uAvionix. If not, please have your aircraft checked for exhaust leaks.

echoUAT Transponder Threshold Adjustment

Adjusting the threshold value on the echoUAT can improve the performance of the transponder monitor.  uAvionix does not recommend changing the value unless directed to do so by uAvionix. The threshold value adjusts the sensitivity of the echoUAT transponder monitor.  Higher values reduce sensitivity, lower values increase sensitivity. To modify the threshold value perform the following steps: [...]

Strobe Wiring Configuration

Strobe Wiring Diagrams The skyBeacon should never be connected directly to a high-voltage strobe power supply.  Connecting the skyBeacon to a high-voltage strobe power supply will damage the skyBeacon. The diagrams below show both the incorrect and correct wiring for utilizing skyBeacon with an existing anti-collision system.
