Aircraft noise directly causes great inconvenience to residents lives and learning activities, and the damage is extensive, but its compensation and countermeasures are very limited. Continuous and momentary noise is high in areas of the airfield, making it difficult to quantify the damage. Therefore, noise distribution was created using the Integrated Noise Model Version 7.0 of the aircraft noise prediction program used by the Federal Aviation Administration (FAA). The area where noise distribution is created is the airfield that educational aircraft are operated, and complaints have been filed due to the operation of many aircraft. Since the impact range of aircraft noise varies depending on the flight path, the flight path has been changed in several ways, to the extent that it does not affect the safety of flight training. It is important to create a noise distribution around the airfield and analyze the noise distribution according to the changed flight path to find a flight path that can minimize damage to residents and ensure the safety of flight training. The noise was analyzed by changing the take-off route from the sea side to the 10° sea. Noise was distributed in the sea where residents were not residing. These results can be used as data for changing flight paths that does not interfere with flight safety and for noise countermeasures in various flight situations. |
