• Modeling airport capacity– Previously
• Used ceiling and visibility to determine VMC, MMC, and IMC conditions and apply associated capacity curve
– Now• Considers wind speed, wind
direction, and time of day• Use special condition curves
– Configuration specific– Wake Turbulence Mitigation for

• Previously– No GDP module
• Now– GDP generator identifies GDPs and assigns expected departure clearance times
• Given flight times and weather dependent airport capacities• Flights assigned arrival slot based on priority
– Distance based tiers– International flights exempt
– Airport specific GDP triggers • Max flight delay• Max queue length
• Next– Airline response and cancellation module– Probabilistic GDP triggers– Probabilistic weather forecast
Ground Delay Program (GDP)Generator

• Model Q-Routes– Previously
• No special treatment
– Now• Allow equipped flights,
between certain city pairs to fly special routes
• Impose aircraft separation standards using restrictions

Oceanic Separation• Previously
– Flights flew unconstrained in oceanic airspace
• Now– Oceanic separation
standards imposed using static restrictions
– Considers lead/following aircraft type/equipage to determine separation
• Next – Incorporate altitude
restrictions– Oceanic in-trail climb and
descent

• Standard Terminal Arrival Routes (STARs)– Previously
• All flights had continuous descent arrivals• Estimated time/fuel inefficiencies by
historical data analysis– Now
• Assign each flight to a STAR – based on route and equipage
• Define more detailed 4-D trajectory – with altitude restrictions
• Standard Instrument Departures (SIDs)– Similar technique implemented
SIDs and STARs

Next Steps• Incorporate Traffic Flow Management (TFM)
– Airspace Flow Programs
• Improve Terminal Approach Control (TRACON)– Update and automate arrival fix and departure fix flows– Incorporate fix balancing
• Improve local and en-route weather effects– Model severe IMC conditions
• Incorporate dynamic events– Dynamic rerouting, dynamic sectorization
• Include Monte Carlo simulation capability– Re-factored source code
• Validation, validation, validation
