Sector Traffic Control (R-Side) is responsible for managing aircraft through the use of radar. 5 Minute TimescaleSector Traffic Planning (D-Side) is responsible for coordinating handoffs with surrounding sectors. 5 20 Minute TimescaleR-Side and D-Side Controllers

Can implement Miles in Trail or Time in Trail requirements.

Facility Flow Planning (TMU)

Pays special attention to weather patterns that can block routes and close airports. Utilizes three strategies for overcrowding and weather. Ground Holding: Delays takeoff times for aircraft heading to crowded destination.Rerouting: Used to maneuver aircraft around weather systems or overcrowded sectors. Metering: Method used to manage flow rates into sectors. National Flow Planning (CFMU)

Centers are staffed by certified flight dispatchers.Generate flight plans based on aircraft type, weight, and loads, weather conditions airport limitations.The flight plan details the flight route, weather, alternative airports, fuel requirements, and take-off loads. Flight Planning (AOC)
