FAA Finds No Significant Environmental Impact for BOS Runway 4-Left GPS-Approaches
The need for additional approach access to the ever-busy and often contentious Boston area has been eased somewhat... for now. This was an important step, as noted in the massive doc... "The Proposed Action is needed because currently there is no IAP of any kind available for approaches to Runway 4L. As such, aircraft arriving to Runway 4L lack vertical and lateral guidance during the approach phase of flight."
