Pilots must now re-learn how to use emergency oxygen masks on planes

The US aviation regulator is requiring new procedures for how pilots and crew use portable breathing equipment during emergencies. This change comes after reports of people using the equipment incorrectly.

This is a small but critical change. When an emergency happens, pilots and crew need to react instantly and correctly. If the instructions for basic safety equipment are unclear or easily misunderstood, it creates a new risk. This rule means airlines must retrain their staff on a fundamental safety procedure.
