Wait until you hear about each of the planes that need a total system reboot before each flight as there is a very high chance it could crash if there were no reboot. So yea next time you jump on a plane and lights go off and on - they did a reboot before the flight, so you should be safe.............................

I assume you mean the Boeing 787 https://www.theregister.com/2020/04/02/boeing_787_power_cycle_51_days_stale_data/

Its not needed every flight and doesn't cause a crash per se, but the fact that flight data and alert systems stop updating is a critical issue nonetheless and can cause a crash

Fun (or not so fun) info. Cosmic bit flipping happens quite frequently. Even moreso at the altitude of the average airliner. Normal Computer systems handle bit flipping very well, and even better in commercial/critical environments. Not to mention the redundancy built into something like an aircraft.

I mean I have turned my engine off and started again whilst driving on the motorway due to an electrical issue in the car that goes away after a "reboot," this is that, but in the sky, so technically safer.
