Airspace Design and Environmental Analysis

NAS-Wide Environmental Modeling

Product Features
Geographic coverage for the entire NAS, through regional and local levels The use of FAA-approved modeling methods for noise and emissions Rapid computation via use of parallel, distributed processing Remote access to the service from any computer Open interface to facilitate interaction

Overview
Environmental modeling is an increasingly important aspect in the evaluation of both existing and proposed changes to airport and airspace operations. The FAA’s Operational Evolution Plan (OEP), as well as the JPDO’s Next Generation Air Transportation System (NGATS), specifically highlight environmental impacts as a major factor to be addressed in the evolving infrastructure, technology, and operational concepts for the National Airspace System (NAS). These future concepts span a vast range of potential operational behaviors, and they require environmental analysis to ensure that they are consistent with emerging environmental constraints.

Benefits
In order to assist NASA’s Virtual Airspace Modeling and Simulation (VAMS) project and other large-scale NASA, JPDO, and FAA efforts in the development and assessment of innovative airspace and operational concepts, the Phase-II effort has completed the development necessary to create a prototype NAS-wide Environmental Impact Model (NASEIM) service capable of computing associated noise and emissions impacts.

Deployment
The proposed NASEIM service is initially targeted for application to the Advanced Concept Evaluation System (ACES) simulation environment being developed under the Virtual Airspace Modeling and Simulation (VAMS) project. By generalizing the interfaces and services designed into NASEIM and leveraging existing web-based protocols, we open up access to NASEIM to other NASA simulation environments.
