Introduction & Objectives
NAS-Wide Simulation Workshop aims to
•
•
•
Review the State-of-the-Art of existing tools/models
Review capabilities suited to NextGen Conops assessment
Identify any gaps in modeling functionality that may need further
developments
Look at the near-term plans for tools (e.g. to see if those gaps are
being addressed)
Identify remaining areas to be considered by tool developers
•
•
We will present two of our NAS-Wide modeling capabilities:
•
RAMS Plus – Gate to Gate NAS-Wide ATC/ATM/Airport model
•
CHILL/SIM-C – System-wide agent-based hybrid modeling platform
All supporting multiple data input sources (ETMS, ACES, ASDI, CTFM, etc.)

Next Steps
• Continuous enhancement of existing components
• Enhanced Weather Modeling (4D Cube, ProbWx)
• Performance based services (modify service levels instead of traffic management/delay)
• Enhanced GDP (Airport Network) model
• Next round of MSP modeling (following RTS @ NASA in Jan 09)
• Transitions between managed/unmanaged airspace (SESAR)
• AOC model improvements (Not easy!!)
