Information about Data Sources
Data is provided by government entities in the country of aircraft registration. Data provided varies from country to country. Contact the agency directly for more information. We are a data aggregator. We do not manage the information contained in the data sources directly.
For aircraft that have transmitted ADS-B position data, we collect that data and store historical position reports. If an aircraft does not have data displayed, we have not picked it up through our telemetry or it has not operated within the previous 24-month period.
