Oscar Avalle Posted June 9 Report Posted June 9 I get a traffic alert (visual and audio) on the ground and in the air, because my GTN750 identifies my own transponder and ADSB output as traffic. I am getting used to it but it is annoying. There must be a way to fix this. Any suggestions or ideas? Thank you. I am attaching a picture of the GTN750 screen with the ghost traffic alert. Quote
hypertech Posted June 9 Report Posted June 9 What is the source of your ADS-B in and out information? 1 Quote
PeteMc Posted June 9 Report Posted June 9 I remember issues from a while ago with a Software release. Do you have the latest software in your GTN and your Transponder (GTX345?). Also as @hypertech mentioned, you may be receiving delayed TIS-B info from a ground station. Does the ghost plane disappear after a little while? That would be typical of a TIS-B latency issue that the GTN eventually resolved on its own. From there you go down the rabbit hole. Have you looked at the Public ADS-B Performance Report (PAPR) to see if your output is within standards? Quote

PT20J Posted June 10 Report Posted June 10 Does it only happen in one geographic area? If so, it could be an issue with the ground based system. Report it and the FAA will investigate. https://www.faa.gov/air_traffic/technology/adsb/adsb_reports/ Quote
