Re: ACARS messages.
Wondering - anti ice probably means for whatever reason- temp sensor ? Or the f/o turned on electric antice and something shorted and started a fire - then sensor wiring burned through, triggering the R fixed window sensor?
ACARS messages: You mean this may have been a fire under the f/o's side window, just like this one in an Egyptair 777 ??
And this was not an electrical fire. The reason for this fire and others like it in the region is likely to be linked to the way crews operate. But I cannot tell you the reason why this happens, because nobody will talk about it. Not even the NTSB or AAIB.
