Jet engines can now combine two emergency power settings into one

US aviation regulators are proposing new safety rules for a specific jet engine model. This engine combines two emergency power settings into a single, longer-duration setting, which current rules do not cover.

For decades, aircraft engine safety standards have assumed specific, separate power ratings for different emergency situations. This new design changes that, allowing a single, more flexible emergency power setting. This means engine manufacturers can innovate beyond the old categories, potentially simplifying pilot procedures during critical moments.
