Should we be concerned about ETOPS (colloquially "Engines Turn Or Passengers Swim") being extended to 300 minutes? That's up to 5 hours of hand-flying a jet with a failed engine.
Of course it's always an issue if an engine does fail, but ETOPS as a certification is there to ensure that airplanes and pilots are not put under unreasonable amounts of stress or issue if and when an engine fails over-water.
Certainly still stressful, but they don’t need to hand-fly it.
