The Federal Aviation Administration has unsuccessfully tested a system called en route automation modernisation (ERAM) for use on regional air traffic control facilities in the US.

The ERAM system was touted to be the FAA’s next-generation air transportation system but a lot of problems were discovered in the system.

The FAA recently signed a new contract with the National Air Traffic Controllers Association (NATCA), but is now not willing to collaborate any further with the association on testing the ERAM system.
