Management Objectives
• Can FAA identify/prioritize the constraints in the system?– Air Traffic Flow Management Delay, Taxi-Out Delay
• Is FAA making the most efficient use of capacity? – Capacity, Throughput, Capacity Efficiency
• Is FAA providing efficient flight trajectories to operators?– En-Route Additional Distance, Level Flight
• How will FAA respond to questions of Airline schedule delay, on-time performance?– On Time Performance, Change in Block Time
• Low Visibility
• High wind• Convective weather
• Schedule Peaks
• Crew Scheduling
• Equip problems, etc.
• Airport Maintenance
• Airport Expansion
• ANSP Investment
• Traffic Management Initiatives
• Airspace Design

Data Sources
• Archived Trajectory and Flight Plan Data
• Aviation System Performance Metrics (ASPM)– Key Event Times: Scheduled Filed Actual, – Basic METAR
• Air Traffic Flow Management Delay (OPSNET)
• National Traffic Management Log (NTML)
• Weather Sources– METAR– NCAR Wind Data at 6-hour intervals

Performance Metrics ReportingIs the metric/process useful?
• Does it lead to improvements in the system?– Data mining identifies specific scenarios for
mitigation.
• Will decision makers trust what is presented?– Weather, Airline Schedules, Airport Capacity– What are similar days?
• Capabilities beyond local METAR– ASPM like tables for Terminal/EnRoute– ASPM like tables for Forecast Weather
