Specifically, do center controllers have to manually amend every flight plan now that En-Route Automation Modernization (ERAM) is fully implemented in the USA? To what extent is the process automated?
I know that, once the flight is en route, if the computer predicts a conflict the controller will need to okay a flight amendment. When flight plan requests are sent in and the center computer checks their viability, do controllers still have to give the okay to amend them and send them back?
Essentially, my question is this: what do FAA center air traffic controllers currently (I say currently because of when ERAM was implemented) do besides talking to the pilot?
