What can be an example of a noise mitigation strategy used by airports?

Creating designated flight paths serves as an effective noise mitigation strategy for airports by directing aircraft along specific routes that minimize noise impact on populated areas. By strategically designing flight paths, airports can manage how and where aircraft fly, often avoiding residential regions during critical takeoff and landing phases. This helps to lessen the noise pollution experienced by communities surrounding the airport.

In addition, designated flight paths can also include altitude restrictions and lateral deviation strategies which can carry aircraft over less populated or industrial areas, further reducing noise burdens on residential neighborhoods. This approach is not only beneficial for local communities but also supports compliance with environmental regulations and enhances the overall community relations regarding the airport's operations.

The other options, while potentially beneficial for different operational aspects of the airport, do not specifically target noise reduction in the same direct and impactful way as creating designated flight paths does.
