Airbus A350 software bug forces airlines to turn planes off and on every 149 hours
Some models of Airbus A350 airliners still need to be hard rebooted after exactly 149 hours, despite warnings from the EU Aviation Safety Agency (EASA) first issued two years ago.
In a mandatory airworthiness directive (AD) reissued earlier this week, EASA urged operators to turn their A350s off and on again to prevent "partial or total loss of some avionics systems or functions".
The revised AD, effective from tomorrow (26 July), exempts only those new A350-941s which have had modified software pre-loaded on the production line. For all other A350-941s, operators need to completely power the airliner down before it reaches 149 hours of continuous power-on time.
Concerningly, the original 2017 AD was brought about by "in-service events where a loss of communication occurred between some avionics systems and avionics network" (sic). The impact of the failures ranged from "redundancy loss" to "complete loss on a specific function hosted on common remote data concentrator and core processing input/output modules".
In layman's English, this means that prior to 2017, at least some A350s flying passengers were suffering unexplained failures of potentially flight-critical digital systems.
Not a power of two. I wonder why 149 hours?

double is neither integral, nor unsigned. At least not on any system/language I've ever worked on (and it's been a few by now).
Other than that, sadly true.

Yeah, inventing colorful stories from mishmashed memories is tiresome. Like fitting an square peg int type in a double round hole.
In actual real life stories that kind of lapsus just don't happen.

What are you, nutty? We're reading a story about it happening to an international airline manufacturer, and you say it doesn't happen!
ROTFL

You're right. No one would ever be stupid enough to farm out work to the retarded monkeys in India.

Even more retarded - letting the same monkeys INTO other countries and allowing them to TAKE OVER "services"...
