Terminal area noise management system and method

A non-transitory, computer-readable storage medium having encoded thereon, machine instructions for route evaluation and selection for airplanes flying in a terminal area of an airport, the airplanes operated by one of a plurality of airlines, each of the plurality of airlines operating one or more airplanes in the terminal area of the airport, based on a multi-variable constrained optimization, variables comprising noise sharing optimization and airplane routing optimization, wherein a processor executes the machine instructions to:

• receive a first route for an airplane;
• receive one or more alternate routes for the airplane;
• and
• assign a route to the airplane, wherein the processor:
• generates expected noise profiles for the airplane, one expected noise profile for each of the first route and the one or more alternate routes,
• computes miles to be flown by the airplane for the first route,
• computes miles to be flown by the airplane in excess of the first route for each of the one or more alternate routes,
• evaluates the expected noise profiles and total miles to be flown by the airplane in view of pre-defined noise criteria, cumulative noise values for each of the first route and the one or more alternate routes, and
• provides a route assignment to the airplane that optimizes airplane noise emission and miles flown so as to equalize an operational burden on each of the plurality of airlines by sharing excess miles to be flown among the plurality of airlines.
