What do you call the software used in airplane that allow the airplane to fly even with a bad shape? I remember there was a name, but I think I forgot it. Does the term apply to other things than airplane? I think modern plane cannot fly without the software.
I am no expert in aeronautics or aerodynamics but I believe the system you may be referring to is called "Fly-by-wire" or more narrowly "Digital Fly-by-wire" or more accurately a "Digital flight control system"
See this Wikipedia article for more information.
Digital flight control systems enable inherently unstable combat aircraft, such as the Lockheed F-117 Nighthawk and the Northrop Grumman B-2 Spirit flying wing to fly in usable and safe manners.
