According to the FAA’s project documentation, the intention of changes associated with “Nextgen” is to create "repeatable and predictable flight paths” and “earlier divergence on departures.” The objective is for flight paths to be as direct to and from the airport as possible to reduce miles and minimize level-offs.
The FAA further asserts “implementation of the ‘Proposed Action’ would not require any ground disturbance or development of facilities, nor would it require local or state action.”
The Project Design Team produced 38 new procedures, 8 new Air Traffic Service (ATS) routes, and 40 airspace redesign proposals. There is no mention of dispersing departures and/or arrivals as a benefit. (The Design Team did not include any citizen involvement or engagement of local elected officials during the design phase.)
Regarding noise, the FAA states “the purpose of and need for the project is to improve efficiency. Addressing noise issues associated with air traffic in the General Study Area is beyond the scope.” However, the FAA later asserts “the Proposed Action will not result in significant noise impacts or reportable noise increases.”
Significant is in the eye, or ear, of the beholder.
