FAA's Airport and Airspace Simulation Model  is an event-step simulation model which traces the movement of individual aircraft and simulated ATC actions required to ensure aircraft operate within procedural rules.

FAA's Airport and Airspace Simulation Model computes the impact on aircraft delay and fuel consumption and uses a wide variety of parameters. Inputs include traffic demand and fleet mix, route structures (both in the airspace and on the airport surface), runway use configurations, separation rules and control procedures, aircraft performance characteristics, airspace sectorization, interactions among multiple airports, and weather conditions.

FAA's Airport and Airspace Simulation Model uses a node-link structure to represent the gate/taxiway and runway/airspace route system. Input parameters depending on aircraft type include: permissible airborne speed ranges for use by ATC, runway occupancy times, safety separations, landing roll and declaration characteristics, taxi speeds, and runway/taxiway utilization. Gate utilization depends on aircraft type and airline.

Users control the timing of the simulation and the desired output reports. A start time and a termination time may be specified for the simulation, as well as a time for periodic reports to be generated. Users provide data regarding the occurrence of various simulation events. These events include aircraft arrival/departure, airport configuration plan changes, and changes in weather conditions.

FAA's Airport and Airspace Simulation Model output consists of reports which provide statistics describing aircraft delay, travel time, and fuel consumption. A user may also request a simulation log containing data on various simulated events.

FAA's Airport and Airspace Simulation Model also has a post-processing animation system which shows the movement of aircraft on the airfield and in the airspace.
