U.S.: Final Phase of Northeast Route Update

The FAA has postponed the implementation date for the final phase of its multi-year Northeast Corridor Atlantic Coast Routes (ACR) project from the previously scheduled Nov. 3, 2022, to April 20, 2023. The FAA said the push-back is to avoid making numerous route changes during the busy summer and winter peaks. The main change of the ACR project is that 150 new or modified routes using performance-based navigation (PBN) procedures are replacing the existing high-altitude route structure. PBN decreases reliance on ground-based navaids.
