What is the primary focus of the Airport and Airway Safety, Capacity, Noise Improvement, and Intermodal Transportation Act?

The primary focus of the Airport and Airway Safety, Capacity, Noise Improvement, and Intermodal Transportation Act is to address the effects of airport noise. This legislation aims to improve the safety and efficiency of the air transportation system while also acknowledging the environmental impact, particularly noise pollution that comes from airport operations.

By including measures that target noise improvement, the act recognizes the importance of minimizing disruption to communities surrounding airports, addressing a significant concern that can affect local residents' quality of life.
