The North American SIMMOD Users Group (NASUG) is an organization for the exchange of ideas and experiences between SIMMOD users primarily working on North American airspace and airport projects.

The Airport and Airspace Simulation Model (SIMMOD™) is an industry standard analysis tool used by airport planners and operators, airlines, airspace designers, and air traffic control authorities for conducting high-fidelity simulations of current and proposed airport and airspace operations.

SIMMOD is designed to "play out" airport and airspace operations within the computer and calculate the real-world consequences of potential operating conditions. It has the capability and flexibility to address a wide range of "what if" questions related to airport and airspace capacity, delay, and efficiency, including questions associated with:

• Existing or proposed airport facilities (gates, taxiways, runways, pads)
• Airport operating alternatives (taxi patterns, runway use, departure queuing)
• Existing or proposed airspace structures (routes, procedures, sectors)
• Air traffic management/control technologies, procedures, and policies
• Aircraft separation standards parameters (weather, aircraft type, flight state)
• Airline operations (flight schedule, banking, gate use and service times)
• Current and future traffic demand (volume, aircraft mix, new aircraft types)
