  5. NextGen ATM-Wx Integration Concept Weather Translation ATM Decision Support Weather Information ATM Impact Conversion Translation of weather data into: • Constraints • Threshold Events Conversion into: • NAS Impacts • State Changes DSTs use impacts to develop TFM solutions Observations Derive Constraint Set Solution Derive Impact Analyses Wx info Constraint info (e.g. wx avoidance) Impact info (e.g. capacity) Forecasts NextGen 4D Wx Data Cube Weather Community ATM Community Primary:NWSFAA Met FAA ATM

  6. Levels of ATM-Weather Integration • Level Zero – No integration • Level One – “On-the-Glass” • Level Two – Translation WEATHER RESPONSIBILITY ATM • Level Three – Impact • Level Four – Decision Support

  7. Forecasted Pilot Avoidance Regions Pilot Deviation Model Improved Weather Forecast Weather Avoidance Field (WAF) Weather Translation Example • The process of taking weather data and combining it with other data elements such as pilot behavior models, safety regulations, operating thresholds, and historical demand information to identify potential constraints in NAS operations due to weather. • NAS Weather Constraint: a limitation on the ability of a given NAS element (e.g., air route, sector) to reach its desired level of service due to weather. EXAMPLE 100 90 80 70 60 50 40 30 20 10 0 -22 -18 -14 -10 -6 -2 2 6 10 14 18 22 Flight Altitude – Echo Tops (16 km) 0 10 20 30 40 50 60 70 80 90 100

  8. FCAA05 +20 min +10 min 0 min -10 min ATM Impact Conversion Example • Using information from the weather Translationfunction, converts it into potential NAS impacts. EXAMPLE FCA Capacity Forecast Matrix Predicted Available A05 Capacity < 75% < 50% Weather Avoidance Field (WAF)

  9. Decision Support • The fundamental goal of Decision Support is to provide overall NAS optimization. • Impact data and state change information used to derive mitigation options to deal with capacity/demand imbalances and provide “what-if” capability for traffic managers – both in the strategic and tactical time frames.

  10. Integration Activities and Goals • Coordinating with Portfolios (e.g., CATM, Improved Surface Operations, TBFM) to identify Wx shortfalls • The main goal of integrating weather into future decision support systems is to increase overall NAS efficiency by: • Standardizing the decision process and outcome (predictability) • Ensuring full and continuous use of enhanced/automated tools during weather events • Optimize use of airspace • Facilitating a more proactive approach to traffic management
