What does the Aviation Environmental Design Tool replace?

The Aviation Environmental Design Tool (AEDT) is designed to replace the Integrated Noise Model (INM). AEDT incorporates advanced modeling techniques and provides a more comprehensive approach towards assessing aircraft noise and its impact on the environment. This tool not only assesses noise but also incorporates other environmental factors, such as air quality and fuel burn, into a single platform, making it more efficient and versatile than the INM.

It enhances the modeling capabilities by allowing for integration of various data inputs and scenarios, which can lead to more accurate and realistic environmental assessments. This modernization is essential for aviation stakeholders aiming to adhere to regulatory compliance and improve community relations regarding noise and other environmental impacts.

The other options represent various programs and models used in aviation but do not offer the same multi-faceted approach as AEDT. The Noise Compatibility Program, for instance, focuses on community strategies to manage noise impacts, while the DNL Measurement System specifically measures day-night average sound levels. The Aircraft Performance Model deals with performance metrics of aircraft but does not serve as a direct replacement for the INM, as AEDT does.
