AEDT & Legacy Tools Comparison
The FAA's Aviation Environmental Design Tool (AEDT) replaced a series of legacy FAA tools for modeling noise, emissions, and fuel consumption. These legacy tools include the Integrated Noise Model (INM), Emissions and Dispersion Modeling System (EDMS), and Noise Integrated Routing System (NIRS).

Improved algorithms in AEDT result in differences in noise calculated at receptor locations, noise contours, emissions output and fuel burn, relative to the legacy models. Updates to AEDT from the legacy models include:

  • Shorter flight path segments to better approximate changes in aircraft state
  • Improvements to input weather data into a study
  • Aircraft data updates specific to noise levels, fuel burn, and airframe/engine mapping
  • Updated fuel consumption models
  • Helicopter emissions modeling using climb-out mode approach

AEDT has a fundamentally different system architecture, design and capabilities from the legacy tools. This allows users to simultaneously model aviation noise, fuel consumption, and emissions within a common interface and common inputs. A summary of caparisons between AEDT and the legacy tools may be found on the AEDT website at AEDT & Legacy Tools Comparisons

  • Improvements to generating VALE reports for multi-year analysis
  • Improvements to the study upgrade process
  • Improvements to the import of EDMS studies
