The FAA just updated flight rules for hundreds of airports

The Federal Aviation Administration (FAA) is changing the rules for how planes approach and depart from certain airports. These updates are necessary because of new navigation technology, new obstacles, or changes in air traffic patterns.

Every time a new building goes up near an airport, or a new navigation beacon is installed, the FAA has to redraw the invisible lines planes follow. These small, frequent updates keep air travel safe and efficient. They also reflect the constant, quiet evolution of the physical and digital infrastructure that guides planes.
