7. 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.

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. 9

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 10
