Eram Development Is Reminiscent of Failed AAS Program

Longtime FAA watchers will remember the FAA’s advanced automation system (AAS), which was contracted in 1990 to replace the agency’s venerable Host ATC system, which had entered service 20 years earlier. AAS was to be the answer to the controllers’ every prayer, until it started to run into technical trouble. In fact, it encountered so much trouble that the FAA cancelled its development in 1994–reportedly at the strong urging of Congress–after expenditures had reached $2.6 billion, without clear indications of when it would achieve operational readiness or its final cost.
