Research is needed to help airports
better define the extent of the problem
better define the potential direct impacts of restricted scheduling windows
identify unintended consequences at both originating and destination airports from restricted scheduling windows on intercontinental routes
propose alternative noise mitigation strategies to achieve similar or better outcomes for communities in the vicinity of origin or destination airports, which maximizing flexible, efficient and effective scheduling for airlines to meet the needs of the traveling public
Having this guidance will help airports develop strategies and implementation of transcontinental route development, while potentially providing more efficient use of facilities with depeaking and better noise outcomes.
