I wonder how many days before you hit 51 is the cutoff where planes need to be grounded - obviously a continuous 51 day flight can't happen without a lot of fancy stuff going on that doesn't apply to the 787, but let's say you're at 49.2 days and considering a .6 day flight, is that allowed or is .2 days within the expected probable variance of your flight time? What if it's closer?
I believe a reboot in such circumstances belongs to the A check[0], i.e. each 25 days of flight time or more frequently than that.
(Franky, I am surprised airplane software runs for days—somehow I assumed they get shut down completely every time they refuel.)
