Introducing ATAC’s Leading Edge Products

ATAC has been providing expert professional products to customers in both the private and public sectors since 1979. As an industry leader in aviation system modeling and simulation, ATAC has been the primary developer of the Airport and Airspace Simulation Model (Simmod PRO!). Also developed by ATAC, Graphical Airspace Design Environment (GRADE) is a state-of-the-art, 4-dimensional computer tool for displaying, analyzing, designing, and evaluating air traffic operations. Range, Airspace and Airfield Data Analysis and Reporting System (RAADARS) is an automated aviation operations data collection, analysis and archiving system for military air training and operations. SkyView provides a comprehensive set of software tools for gathering aviation performance and supporting data, measuring and baselining operations, and helping to design, implement, and evaluate operational improvements. Aviation models developed and available through ATAC span a wide range of needs for addressing aviation operations, capacity, environmental, safety, and economic challenges.

ATAC’s products and services include development and application of custom computer models, simulations, decision aids, and analysis tools; expert consulting in air traffic operations; advanced systems research and development; and studies and analyses in a number of areas, including airport planning, airspace operations design and analysis, advanced technology evaluation, cost-benefit analysis, and environmental impact assessment.


Advanced Simulation Tool for Analyses

Simmod PRO!® provides the flexibility and power of true rules-based modeling capability through the innovative implementation of a generalized simulation scripting language. This greatly expands the capabilities to simulate the dynamics, variability, site-specific features and situation-specific factors in air traffic operations. Simmod PRO! was developed in 1997 and maintains its state-of-the-art capabilities through continuous application for customers such as FAA and DoD for their most complex airspace and airfield operational modeling and simulation challenges.


Simmod PRO!‘s modeling power is derived from the user-defined rules that query the state of the simulation and provide dynamic decision-making. Each step of a flight can be controlled based on user-defined rules that respond to the ever-changing conditions in the air or on the ground. This ability allows the modeling of:

  • Dynamic airfield and airspace rerouting
  • Complex taxiing operations
  • Departure queue sequencing
  • Ground vehicles (e.g., towing, fueling, catering, baggage)
  • Disruptive events (e.g., weather, system failures, runway closures, A380)
  • Human resources and activities (e.g., controllers, pilots, airline)
  • Advanced operating concepts
  • Complex interactions among neighboring airports


The rules-based input provides for “If-Then” capability that specifies the actions to be taken by the simulation based on the state of the system. Simmod PRO! is faster than real time simulation application, for it can simulate thousands of flights in one minute and can run on any desktop configuration, requiring no special hardware. The latest release (version 8) includes a number of enhancements to the features as well as optimizations throughout the code to improve ergonomics and responsiveness. Additionally, the user interface has been recompiled with Java version 7, with an updated look-and-feel. Supported users can obtain this release from our support website.
