Every few weeks, the FAA redraws the invisible lines planes follow to land and take off

The Federal Aviation Administration regularly updates the specific flight paths and safety rules for planes landing and taking off at various airports. These changes happen because of new navigation technology, new buildings, or shifts in air traffic needs.

These are the invisible rules that define how planes move through the sky. Each update means pilots must learn new procedures, and air traffic controllers must manage new patterns. It is a constant, quiet rewiring of the national airspace, happening every few weeks, airport by airport.
