Title: OPTIMIZING AIRCRAFT CONTROL BASED ON NOISE ABATEMENT VOLUMES
Abstract: An aircraft control system 100 and method to optimize aircraft control based on noise abatement volumes. A noise abatement component 114 computes optimal flight and engine control based on a line-of-sight distance to minimize direct operating cost (DOC) while complying with community noise regulations.

Claims: number: 1
text: An aircraft control system (100), comprising:
a processor (108) that executes the following computer executable components stored in a memory (110):
number: 2
text: The system (100) of claim 1, wherein the noise abatement component constrains admissible control of the aircraft to comply with noise regulations, wherein the admissible control is a control history that accurately complies with operational and performance constraints of the aircraft.
number: 3
text: The system (100) of claim 2, further comprising a modeling component that models how sound from an engine of the aircraft varies with thrust and distance of the aircraft from ground, wherein the noise abatement component can generate data to employ for increasing thrust of the engine, and thus sound produced by the engine, while complying with maximum sound pressure level permitted on the ground.
number: 4
text: The system (100) of any preceding claim, wherein engine thrust approaches optimal control as altitude increases while complying with noise restriction levels on the ground.
number: 5
text: The system (100) of any preceding claim, wherein engine thrust is decreased when approaching locations where noise restriction is required, based on the distance to a geographic point of interest in order to comply with noise regulations relative to the geographic point of interest.
number: 6
text: The system (100) of claim 5, wherein noise is a control variable that limits the engine control.
number: 7
text: The system (100) of any preceding claim, further comprising an artificial intelligence component that performs a utility-based analysis in connection with optimizing the DOC and respective noise abatement.
number: 8
text: The system (100) of any preceding claim, wherein the noise abatement component factors noise level at the ground.
number: 9
text: The system (100) of any preceding claim, wherein speed through the noise abatement volume is determined based on thrust that is constrained to comply with noise regulation.
number: 10
text: The system (100) of any preceding claim, wherein the noise abatement component generates predefined routes for optimal noise, fuel, and time as a function of class and size of the aircraft.
number: 11
text: The system (100) of any preceding claim, wherein the noise abatement component employs a noise de-rate setting to facilitate regulating thrust to limit the amount of noise produced by engines of the aircraft.
number: 12
text: A method (700) comprising:
employing a processor to execute computer executable components stored in a memory to perform the following acts:
number: 13
text: The method (700) of claim 12, further comprising using the noise abatement component to constrain admissible control of the aircraft to comply with noise regulations, wherein the admissible control is a control history that accurately complies with operational and performance constraints of the aircraft.
number: 14
text: The method (700) of claim 13, further comprising using a modeling component to model how sound from an engine of the aircraft varies with thrust and distance of the aircraft from ground, and using the noise abatement component to generate data to employ for increasing thrust of the engine, and thus sound produced by the engine, while complying with maximum sound pressure level permitted on the ground.
number: 15
text: A computer program product for facilitating aircraft noise abatement, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to:
