I believe they test the theory in test rides by shutting down 1 engine in flight to make sure the remaining engine can sustain flight. BUT, in this case of a totally mangled nacelle changing the airflow and flight characteristics of the wing and the control surfaces, I doubt this plane handled the same as it would had an engine just been shut down but no change to its physical aerodynamics. Pilot did a fantastic job.
I was wondering if they do that kind of emergency gotchas in simulators during training. Depending on location of the hole in the fuselage, it would have differing affects on the aerodynamics. Afore wing would be completely different than aft wing. Am I wrong?
There have been other truly detached engines. Far bigger change.
I don’t recall how many seem to be catastrophic or not so. Mostly probably depends on how many other engines there are.
Thus the danger of fewer engines today.
