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?

Must be building karma so his Viagra spam gets on the front page Journal list. Or maybe there is an overflow bug he saw in the moderation system with just the right combination that he is hoping to exploit to spread his Viagra spam.

Oops, I meant that as a joke, but guess I was not obvious enough in the disclaimer (or took into consideration a good chunk of people would not read it).
Also, "flamebait" as the mod? Not sure that is what I think of when I think of that term. Flamebaiting is more like, "Of course he would say that, he's a Jew." Basically trying to prod someone into losing their cool or, like Wikitionary put it: "Content in an online forum, such as a newsgroup, with the intent of provoking anger, resulting in flames and sometimes flamewars."
Either way, apologies for any offense.
