First report after the airline audit. On 26–27 September 2026 about 2,000 flights across the archive were reassigned to their real airline (an old rule guessed the airline from the radio address, which is allocated by country, not by airline). This report uses the corrected data. Helicopters and military aircraft are now excluded from airline rankings. Details: Archive, Data Quality tab.
Independent observations from one fixed residential terrace. These figures are not official airport totals or certified airport noise mapping.
