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 [...]
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 [...]
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.
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: [...]
It’s all about the setup: In aviation, everything is about the setup. The preflight, the pilot’s health, the pilot’s familiarity with the aircraft, and the details of the flight determine 99% of the outcome. ADS-B evaluation flights are no different. Poor behavior and a lack of understanding lead to failed reports, more than a little [...]
The only impacted aircraft are those with active (interrogating) TCAS systems. These systems provide aural resolution advisories, and will generally be marked as TSO-C119. TCAS systems are required for Part 135 operations on large turbine-powered aircraft. Aircraft equipped with TIS or ADS-B In systems for traffic awareness are NOT impacted. Also not impacted are TCAS-like [...]
(These are the guidelines that were suggested during the FAA rebate program back in 2019. 15-20 minute flights are usually plenty for getting valid ADS-B data) To summarize the requirements of AC20-165B (see links below): The performance flight should take place for a minimum of 30 minutes from wheels up. The aircraft should climb to [...]
Once the tailBeacon has been installed it is required that the equipment be tested to show it meets the FAA requirements for ADS-B OUT. An Operational Flight Evaluation (often referred to as a performance flight) must be performed and verified by the FAA. Additionally, the installer may verify performance on the ground using an ADS-B ramp test [...]
