We have developed this resource center to give the surrounding communities and pilots information on efforts to reduce aircraft noise around Centennial Airport. The FAA does not recommend noise sensitive development within the 65 Ldn. Due to advances in aircraft and engine design, Stage III category was created due to the significant decrease in engine noise.
Hush kits are similar to mufflers on a car.
The hush kits will significantly decrease engine noise so that they can be classified in the next higher, more quiet, stage. Examples of Hush Kits on a Gulfstream, Hawker, and Learjet Advances in technology are improving engine noise to the point where the airframe creates more noise on final approach than the engines.
