Would be realistic to have aircraft damage and/or performance issues for: high G situations (ex: hard landing or high G in flight maneuvers) , exceeding 100% N1 for certain period of time (ex: engine failure or fire), icing development which effects aircraft performance in icing conditions (ie: would require addition of an anti-ice feature or altering flying altitude to prevent) and damage for landing off the runway (ie: aircraft landing gear collapse upon landing off runway or automatic crash if you land on water).
I totally understand that Global is the priority and appreciate the hard work that the devs are doing. This would just be a cool & realistic feature for the future. Feel free to comment
