Future air traffic control concepts include many new roles and responsibilities among controllers, air traffic management, pilots, and flight dispatchers. An important aspect of future concepts specifically aims at mitigating operational constraints caused by adverse weather conditions. Therefore, it is important to evaluate the current weather information available to these operators to assess future weather requirements for National Airspace System operations and safety. In the present paper, I compare and contrast the procedural requirements in Federal Aviation Administration Order 7110.65R that en route and terminal controllers follow when they use weather-related information. I summarize what weather information is available at the controller workstation and outline how controllers use this information operationally.
