actually, HF radios with digital, encrypted & authenticated communication work GPS works, too internet safe for business fliers but not the pilot? please. it doesnt mean the whole plane relies on internet.

those 3 should probably be added to current planes, regardless.

i'm not sure why you think there is a single system with a "CPU" in a plane either. there's multiple independent systems - some electronic, some analog.

all this not much to do with visualization or python, in fact... and software glitches in planes do happen, by the way.

I think you're missing point. For a system to be allowed on a passenger plane, it must be certified.

That means that it has to go through actual real QA (something foreign to modern Software science.)

You want to put in a glonass receiver? sure, but it has to operate independently of the GPS system, and it cannot replace any other navigation system unless the FAA allow it.

the point is each system must be robust (i mean really robust) and able to work past the extremes independently.
