Late last year, an excellent article by Barbara Castleton was added here, in the ai-Rchives. A couple weeks ago, quite a few people started sharing this article at various social media sites related to airport impacts.
The November 2017 aiREFORM Post included a scrollable PDF copy, with footnotes added. Well, six months later, we decided to take a fresh new look at Barbara’s article, relate it to what FAA has done since, and create a new version, with new footnotes added. Of course, we did NOT look at the old footnotes until everything was finished. It is interesting to see how little has changed, and yet, too, how much more clearly the NextGen impact issues appear to be coming into a sharp focus.
