Bug? Sounds like a deliberately programmed in feature. Do they have a record of which software engineer programmed and verified each packages? Of course not. They are all in India or something.
Are the planes not supposed to land from that direction?
It would be a huge misunderstanding from the programmers, yes, but if a pilot approached the runway from the “wrong” direction, it would be a really bad feature for the screen to just go dark.
Of course they do. And if it's repeatable, it won't take long to figure out what set of weird conditions trigger the problem.
