An example method for modifying a flight path of an aircraft includes receiving real time positioning estimates for an aircraft, receiving an actual navigation performance (ANP) of the aircraft informative of uncertainty in the position estimate, receiving a required navigation performance (RNP) instrument flight procedure for the aircraft, receiving spacing input from an air traffic controller that indicates spacing requirements between the aircraft and one or more other aircraft, receiving information relating to communities underneath the flight path, calculating, by a system onboard the aircraft, a modification to the flight path to be flown by the aircraft that causes the aircraft to remain within the containment boundaries of the RNP instrument flight procedure while reducing noise impact to the communities underneath the flight path and meeting the spacing requirements of the air traffic controller, and displaying a visual representation of a modified flight path for the aircraft.

Performance-based track variation for aircraft flight management

An example method for aircraft traffic spacing and timing control with flight path variation of an aircraft includes receiving information of aircraft traffic for an area, determining an aircraft spacing plan for the aircraft traffic for the area based on spacing requirements due to separation standards or flow management constraints for the aircraft traffic, determining that a modification to a flight path of an aircraft is required to meet a longitudinal spacing requirement between the aircraft and one or more additional aircraft of the aircraft traffic based on the aircraft spacing plan, determining a flight path modification to the flight path for the aircraft based on the modification that causes the aircraft to remain within associated margins of the RNP instrument flight procedure and alters the longitudinal spacing between the aircraft and the additional aircraft of the aircraft traffic, and assigning the flight path modification to the aircraft via a data communication link.

Aircraft traffic spacing and timing control with dynamic flight path variation

An example method for flight path variation of an aircraft for noise management includes receiving noise inquiries of a community related to aircraft noise during flight over the community, receiving an output from noise sensors positioned within the community, determining a noise distribution plan for additional aircraft flying over the community so as to steer the additional aircraft and distribute additional aircraft noise in response to the noise inquiries and the output from the noise sensors, and based on flight path data of the additional aircraft and the noise distribution plan, assigning a flight path modification to aircraft via a data communication link. The flight path modification informs the aircraft to adjust the flight path to remain within associated margins of a required navigation performance (RNP) instrument flight procedure and to reduce noise impact to the community underneath the flight path.

Community noise management with aircraft dynamic path variation

Systems and methods are described for dynamically generating flight departure profiles that are in compliance with aircraft emission limits. Emission limits may include noise abatement limits. Flight departure profiles may be generated on a flight by flight basis, and/or may be based on then-current conditions such as wind speed, wind direction, and ambient temperature.
