AIRSPACE CONCEPT EVALUATION SYSTEM

The Airspace Concept Evaluation System (ACES) addresses the need to examine the costs and benefits of novel ATM operational paradigms and is critical for identifying the most promising concepts. To perform this essential function ACES is being developed to enable evaluation of the system-wide effects of proposed air transportation concepts intended to reduce delay, increase capacity, and accommodate the forecasted growth in air traffic. The ACES capability captures the key feedback response mechanisms of the National Airspace System (NAS). ACES is a multi-fidelity non-real-time modeling and simulation system with full gate-to-gate representation of all the major components of the NAS. The agent-based modeling approach that is being used represents the individual behaviors of the airspace participants and captures the critical ripple effect of one user's actions on other system participants. This modeling approach isolates the individual models so they can continue to be enhanced, improved, and modified to represent new concepts with low development impact on the overall simulation system. ACES Build 4 is now operational and has been utilized to address multiple advanced ATM concept analyses as well as futuristic NAS demands including 2 and 3 times increased traffic levels. Future software releases will enhance the modeling toolbox by adding new NAS component models, by increasing model fidelity, and by insuring usability for airspace analysts.
