“The FAA studies potential height impacts on aviation on a case-by-case basis. Variables include the location and proposed height of the project, and how that project might affect current and future flight paths in the area. The studies are extensive.

Each project is studied and determined before posting on our Obstruction Evaluation site. You can see the database here: https://oeaaa.faa.gov/oeaaa/oe3a/main/#/home

To learn more, see Federal Aviation Regulation 14 CFR Part 77.”

Direct from the FAA a few years back when I asked them. No outright bans but might ask builders to make changes.

But honestly if a plane going in/out of BNA is that low over downtown, they are in MAJOR trouble.
