Describe the flow of flight-plan information through Air Traffic Control System Command Center (ATCSCC) and Traffic Management Units (TMU).

Description should include connecting the participating facilities to ensure that the flight-plan information is passed along to the various air traffic controllers prior to the arrival of the aircraft. Description should also include functions of traffic management units and TMIs to avoid over-saturation of airspace and airports (e.g., ground delay programs [GDPs], ground stops, etc.).

Process/Skill Questions:

• Why is it important for the flight-plan information to be relayed prior to the arrival of the aircraft?
