A method for flight path variation of an aircraft scheduled to fly over a community for noise management, wherein a flight path of said aircraft is based on a required navigation performance instrument flight procedure for the aircraft, wherein the RNP instrument flight procedure indicates a fixed-route accuracy and containment boundaries (136, 138) required during flight for the aircraft to fly a path between two points along a flight path, and wherein the containment boundaries are defined by a flight path centerline with limits determined by associated margins (144, 146), said method comprising: receiving, at a communication interface of a ground based computing device, information comprising noise inquiries of said community related to aircraft noise during flight over the community, said noise inquiries comprising inputs from the community regarding current and future noise mitigation requests; receiving, at the communication interface of the computing device, an output from one or more noise sensors positioned within the community, wherein the output indicates a noise level reading; validating, by the computing device, the information comprising noise inquiries of the community based on comparison of the information with the output from the one or more noise sensors positioned in the community to arrive at a consensus range of values for the noise level, wherein when noise inquiries from the community do not match noise level readings from noise sensors positioned in the community, the noise inquiries are considered erroneous; determining, by the computing device, a noise distribution plan for said aircraft so as to steer said aircraft and distribute aircraft noise in response to the noise inquiries and the output from the one or more noise sensors, comprising determining modified flight paths for said aircraft based on aircraft-specific noise footprints of said aircraft; based on flight path data of said aircraft and the noise distribution plan, determining, by the computing device, a flight path modification for said aircraft; and outputting to said aircraft said flight path modification via a data communication link, wherein the flight path modification is determined to adjust the flight path of said aircraft to cause said aircraft to remain within the associated margins of the RNP instrument flight procedure and to reduce noise impact to the community underneath its flight path. receiving, at a communication interface of a ground based computing device, information comprising noise inquiries of said community related to aircraft noise during flight over the community, said noise inquiries comprising inputs from the community regarding current and future noise mitigation requests; receiving, at the communication interface of the computing device, an output from one or more noise sensors positioned within the community, wherein the output indicates a noise level reading; validating, by the computing device, the information comprising noise inquiries of the community based on comparison of the information with the output from the one or more noise sensors positioned in the community to arrive at a consensus range of values for the noise level, wherein when noise inquiries from the community do not match noise level readings from noise sensors positioned in the community, the noise inquiries are considered erroneous; determining, by the computing device, a noise distribution plan for said aircraft so as to steer said aircraft and distribute aircraft noise in response to the noise inquiries and the output from the one or more noise sensors, comprising determining modified flight paths for said aircraft based on aircraft-specific noise footprints of said aircraft; based on flight path data of said aircraft and the noise distribution plan, determining, by the computing device, a flight path modification for said aircraft; and outputting to said aircraft said flight path modification via a data communication link, wherein the flight path modification is determined to adjust the flight path of said aircraft to cause said aircraft to remain within the associated margins of the RNP instrument flight procedure and to reduce noise impact to the community underneath its flight path.
