Boeing 787s must be turned off and on every 51 days to prevent 'misleading data'
I am going out on a limb here but I seem to remember reading somewhere that airliners do have maintenance schedules that are very strictly kept, for obvious reasons. If the maintenance schedule is N days, then any news article pointing out how amusing it is that an airliner needs to be rebooted every >N days is at best sensationalism, at worst pure fearmongering.<p>I don't know for a fact this is the case here for the 787, but I think there are far better things to worry about when it comes to technical security in airliners than how often they need to be rebooted. For example, whether the on-board WiFi is sufficiently separated from the in-flight systems, and (as discussed recently here on HN) whether the advent of touchscreens for critical flight systems is sufficiently durable, tested and redundant.
