The FAA just updated its rulebook for how it defines US airspace

The Federal Aviation Administration (FAA) has formally updated the document that defines all US airspace. This means the FAA can now use a new, simpler process to change how it designates air traffic service routes and reporting points.

The FAA manages the busiest and most complex airspace in the world. Every change to air routes or reporting points used to require a formal rule-making process, which is slow and expensive. This update means the FAA can now make these changes by simply updating an internal order, making the process much faster.
