The FAA has begun initial deployment of a new time-based flow management (TBFM) system that the agency says will optimize the flow of aircraft into busy airspace. TBFM, which was recently installed in all 20 en route air traffic control centers, supersedes the three-year-old traffic management advisor “as a time-based scheduling tool that meters aircraft through all phases of flight to deliver the correct number of aircraft to airspace sectors and down to the runway at the exact pace at which the aircraft can be accommodated.”
National Airspace System Voice Switch
The FAA claims the NextGen Air Transportation System initiative is progressing, according to its recently issued NextGen Implementation Plan report, which projects a reduction in delays of 41 percent by the end of the mid-term implementation period in 2020.
The FAA awarded Harris a contract on Tuesday potentially worth $291 million to replace legacy voice switches at ATC facilities with an Internet Protocol-based network under the National Airspace System Voice System (NVS) program, considered foundational to the NextGen ATC modernization effort. Current voice switches, some dating to the early 1980s, operate independently at individual ATC facilities.
