Polish airline listed as Heathrow's noisiest Matt Gorman of Heathrow, said: "The launch of the Fly Quiet programme signals our firm commitment to being transparent about aircraft noise and our progress in reducing its impact on local communities." John Stewart, of the noise campaign group HACAN, welcomed the publication of the tables, calling it "a constructive move to improve the noise climate." Six criteria were applied to the airlines assessed in the table: Noise efficiency - a calculation designed to take into account of the greater number of passengers carried by larger, noisier aircraft Noise certification - according to Heathrow, this "favours the airlines operating best-in-class, modern, quieter aircraft more frequently." Steady approach - reducing the amount of noise as it require less engine thrust Staying within "noise preferential routes," away from more densely populated areas Night-time operations - part of a voluntary arrangement where aircraft scheduled to land between 04.30 and 06.00 will not land before 04.30. No arrivals before 06.00 for flights scheduled to land after that time unless there are extenuating circumstances (such as poor visibility). LOT was below the performance target for both the second and third categories, while BA was the only airline to exceed performance in each category for its short-haul flights.
