Among the Federal Aviation Administration’s (FAA) main priorities is to keep all users of our national airspace safe. To maintain the safest aerospace system in the world, the FAA must make sure the national airspace is navigable and free of obstructions.
When anyone proposes new construction or proposes to alter existing structures near airports or navigational aids, the FAA determines how the proposal would affect the airspace.
These FAA determinations about the appropriate height of buildings, wind turbines and meteorological towers near airports, and how they are lighted and marked, contribute to the safe navigation of our skies.
The agency has updated its guidelines for the proper way to light and mark obstructions affecting navigable airspace. Advisory Circular 70/7460-1L for Obstruction Lighting and Marking is effective immediately. It cancels Advisory Circular 70/7460-1K, dated February 1, 2007.
