A new jet engine can combine two emergency power settings into one

US aviation regulators are creating new safety standards for a specific jet engine. This engine combines two emergency power settings, usually separate, into a single function.

Jet engines have separate power ratings for short (30-second) and slightly longer (2-minute) emergencies when one engine fails. This new design merges them, which means pilots will have a simpler, more consistent power response during critical moments. This change could simplify pilot training and reduce decision-making complexity in high-stress situations.
