Had to Google the meaning of squadron service and came across this older article: Software Bug Halts F-22 Flight as it crossed the international date line So much for test coverage.
Speaking of software, why does the forum software submit my article when all I did was trying to switch browser tabs with the link caption dialog still open?

That was crossing a given longitude. That happened in airliner INS systems too, IIRC. I can see the potential for this, having done some ARINC429 coding. The way angles are represented there is asking for trouble.

That isn’t avionics; please post it under IT/Website. I also do not understand the description.
My memory might be wrong and the F22 incident be the only one.
There was definitely at least one more such occurrence with F-16 in Israel: when they descended towards the Dead Sea, which is 400 m below MSL, some code in the avonics would throw a divide by zero exception and trigger a reboot.
Yes I remember that too.
