Future Air Traffic Management Requirements for Dynamic Weather Avoidance Routing

We present information requirements for a future air traffic management (ATM) system focusing on dynamic weather avoidance maneuvering. Assuming a net-centric operation (NCO) that provides a mechanism to inform all users of weather forecast information, hazardous weather constraints, and weather avoidance routing requirements, the future ATM system can move away from static jet route routing toward a system where routes are defined dynamically, adjusted during the course of the day as required by traffic demand and the geometry of severe weather constraints. Such an operational concept will be particularly useful for time periods where weather is a major constraint to operating the national airspace system (NAS), and traffic delays or reductions in safety are often the result
