An airport noise map is another name for a computer program that tracks flight paths of commercial airlines. London has an airport noise map system where people can log on to a website, type in their postal code and a certain time of day, and bring up a map which highlights the airplanes that will be flying over their home, and what time they will do so. It also gives information such as the plane's altitude and speed, and what type of aircraft the offending plane is. The information from the airport noise map is not in real time for airport security reasons. This program gives web users a convenient platform from which they can complain about the aircraft noise they hear. With the use of an airport noise map, people can pinpoint what flight was flying at a certain time, and report it to the proper authorities. This is proof that the airports have become more sensitive to this issue, and are making the attempt to improve the communities that they serve.
