The FAA changed how planes fly in bad weather, but only for some routes

The US aviation regulator updated the required altitudes and changeover points for planes flying under instrument flight rules on specific routes. This means pilots will follow new instructions for navigating certain federal airways and jet routes when visibility is poor.

These are small, routine adjustments to how air traffic controllers manage planes in bad weather. They reflect ongoing changes in the national airspace system, like new navigation technology or updated flight paths. The changes aim to keep air travel safe and efficient, but they do not represent a major shift in how air traffic is managed overall.
