In 2019, the FAA began working on major updates to the Northeast Corridor Atlantic Coast Routes (NEC ACR) to reduce delays and improve throughput for high altitude traffic to and from the Florida Metroplex. The changes also will reduce airspace complexity, reduce radar vectors/reroutes and accommodate more operators at their requested altitudes.

Originally targeted for completion in November 2020, much of the airspace project has been pushed into fall 2022, due to COVID-19.

The project is following a phased implementation by publishing new procedures on one chart date, then implementing on the next chart date. This allows operators to update their navigation databases ahead of each cycle period.

The next major update will take place on Sept. 8, 2022, with numerous changes released, but identified as “N/A” in NOTAMs.

On Nov. 3, 2022, these routes will be enabled and active replacing older routes. Operators will be expected to file these routes from that point forward.

After this, there may be a few minor procedural changes in December 2022 bringing the NEC ACR project to completion.
