The Boeing 787 Dreamliner has a rather striking softwarebug. There arise problems as to the systems of the plane, not even by 248 days to be ‘rebooted’. If that does not happen, the electric generators fail to work.

The Guardian reports that the American aviation authorities a warning is issued. There is a problem in the four electric generators that the Boeing 787 on board. If they have more than 248 days, one behind the other switched on, they can go to a ‘failsafe mode’ switch and that means that all electricity in the airplane can fall. Of course, it can have catastrophic consequences if the aircraft is at that moment hanging in the air.

After 248 days problems probably has to do with a 32-bit integer overflow. Converted to the number of hundredths of seconds is to 248,55 days, i.e. the number of 231 exceeded. Moreover, Boeing has not confirmed that an integer overflow is the cause of the problem.

There is a temporary solution, and that is rather simple: the system must be rebooted. As long as there occasionally is restarted is the Dreamliner safe to use, that is, in the opinion of the aviation authorities. Boeing reports that its planes now all have a time off and on again.

Until the fourth quarter of this year to airlines for their Dreamliners still reboot. Then a software update is released that the problem permanent repairs. Or update over-the-air entering is not clear.
