PP, thanks. And to make my point about software, who else has been affected (again) by the February bug on the clock displays? This year, every now and again, our elapsed timers will count above 59 seconds in the seconds windows. If the software to drive a simple clock can not be bug free, what chance be we have with flight control software where one of the inputs is time? Do your flight control software testing for eleven months and no fault will be found. Yet these aircaft have repeated problems in February. And some of us are expected to fly using the automatics by default?
