Flight Procedure Noise Modeling and Validation for Current and Future Aircraft

As air travel continues to grow and evolve, noise heard by communities remains an important factor in environmental impact assessments. Advanced operational flight procedures where aircraft are flown strategically to reduce noise levels are potential methods to reduce aircraft noise. Examples include: delayed deceleration approaches, where aircraft maintain higher speeds and therefore remain cleanly configured and at lower thrust levels for a longer period of the procedure, climb control on departure, where thrust levels are lowered in specific regions, and super short takeoff and landing procedures. The fleetwide potential for noise abatement via flight procedure design is dependent on aircraft performance capabilities and airspace constraints, which must be factored into the operational design. This presentation will discuss an aircraft performance and noise modeling framework to evaluate and design these advanced operational procedures. In addition, methodologies to validate the performance and noise impact modeling of this framework using ground noise monitoring systems and operational radar data are shown. Finally, ongoing work in noise modeling and validation of future urban air mobility aircraft is also presented.
