A small Oklahoma airport updates its name, and its flight rules change with it

The Federal Aviation Administration proposes to update the flight rules for Burns Flat, Oklahoma. This change comes because the localizer outer marker, a navigation beacon, has been decommissioned.

Airspace rules are highly detailed and depend on specific ground infrastructure. When a piece of that infrastructure, like a navigation beacon, is removed, the rules for how planes fly in that area must also change. This ensures that instrument flight rules, which pilots use in bad weather or at night, remain accurate and safe.
