How to use this page: When you identify a NAS issue — weather, equipment, volume spike, or an airspace event — add it as a Constraint (draw it on the Map or add manually). Then click Model Scenario → on any constraint below to immediately jump into the Scenario Workbench with the relevant airport and TMI type pre-filled. This is the starting point of the ATLAS decision workflow: Identify → Constrain → Model → Mitigate → Brief.
