CSSI develops simulations and models to analyze specific issues and provide solutions to important challenges. We apply the full range of modeling and simulation techniques to answer “what if” questions, solve complex problems, and enable the efficient operation of large-scale systems.

Environmental Models
  Airport Air Quality Model: Emissions and Dispersion Modeling System
  Local, Regional, and Global Aviation Air Quality and Noise Model: Aviation Environmental Design Tool (AEDT)
  Alternative Fuels Model

System-Level Simulations
  National Airspace System Performance Analysis Capability (NASPAC)
  Combined Airspace and Human Performance Simulation
  Beacon Code Assignment simulation and Optimization
  Airport Runway Capacity Simulation
  Weather Impact Traffic Index (WITI)

Fundamental Models
  Six Degree of Freedom Aircraft Model
  Flight Management System (FMS) Model
  Aircraft Fuel Burn Model
  Optimal Trajectory Generator (OPGEN©)

CSSI is the developer of the Emissions and Dispersion Modeling System (EDMS), the FAA-required local air quality tool for assessing the contribution to local air quality from airports. EDMS computes emissions inventories and estimates concentrations from all emission sources found at airports including: aircraft, ground support equipment, motor vehicles, fire fighting training operations, and stationary sources such as power plants, fuel storage, and maintenance operations.

EDMS 5 was released in 2007 and is a state of the art model that incorporates an advanced approximation of aircraft particulate matter emissions that considers smoke number, unburned hydrocarbon, and sulfur emissions; a sophisticated airport configuration selection utility with associated capacities; and a queuing model that accurately accounts for ground delays at airports.

EDMS 5 is the basis for the FAA’s next-generation emissions and noise interdependency analysis tool suite, the Aviation Environmental Design Tool (AEDT) that will be available in 2012.
