Airplanes can now connect critical systems to the internet, if they meet new security rules

The US aviation regulator is allowing a new digital system on airplanes that connects previously isolated internal networks to external internet sources. This means aircraft can use more modern digital tools, but they must meet new security standards to prevent outside access.

Airplane systems have always been designed to be isolated from the outside world for safety. This new rule means that isolation is ending for some critical systems. It opens the door for more advanced digital operations on planes, but also creates new security risks the US aviation regulator must now regulate.
