Why are you so sure the blanking is not caused by a bug? “On error clear screen” seems like a pretty good way of making it very clear to the pilot that something has gone wrong and they need to fall back to manual procedures (rather than looking at displays that may have gone stale or be showing bad information).
- t0mas88 7y agoI don't know a single airplane that does that and I've flown quite a few types. It's normal to have error detection and the way to show it is to cross out (red lines, black background) the failed information on the screen. Not blank the whole thing. The units are fairly independent in a modern system, communicating via data buses. So this sounds like a case where the bug made a unit emit something really bad on that bus to make them all go blank.
