Well to start with this would only work on fly by wire airplanes. I don’t consider it an attractive idea to introduce this kind of computer program.
Secondly this would mean that a pilot-less airplane will fly the pax, this involves the whole discussion if this is acceptable.
Third problem is that by allowing some input you could for instance tell the computer about a fictive thunderstorm that it should avoid so it flies to a area of your choice, blowing up an airplane over the wrong area is bad enough.
The idea is noble but in reality everything isn’t coded as it is in the computer world. Every situation needs interpretation and man can only do this.
