Environmental Modeling

Enhancing Environmental Efficiency of Air Travel

Copy-2-of-EMS-2-smallOne of the greatest concerns in the aviation industry is its’ environmental footprint. Metron Aviation develops modeling techniques and systems addressing fuel consumption, fuel efficiency, greenhouse gas generation, emissions related to local air quality and aircraft noise that guide stakeholders to greater environmental efficiency. Metron Aviation developed and supported the Noise Integrated Routing System (NIRS) for the FAA for more than a decade and is a member of the team developing the next-generation FAA environmental tool, Aviation Environmental Design Tool (AEDT). Our environmental model development process is based on the following:

  • Review of Underlying Mechanisms – Metron Aviation reviews the underlying physics and chemistry for the impacts being modeled to ensure that any key assumptions or limitations in the modeling techniques are well understood.
  • Algorithm Development – These algorithms are consistent with the underlying mechanisms and technical requirements of the model (accuracy, speed, scope of input data, etc.) as well as global best practices.
  • Modeling System Development – Metron Aviation integrates algorithms with appropriate data assembly, reporting and work-flow-management software within an integrated architecture. Testing is performed, user documentation is developed and training materials are prepared as appropriate.
