Thank you, Sir..
I'd be interested to find out if that indicates the warning Flag is unavailable, or that it is ON. Isn't ACARS just a sensing and recording (reporting) system? Kind of like a snitch? It doesn't compute, so how would it "know" that the PFD is bananas re: a/s? Is it told by the FMC what to report, or does it just record anomalous data? "Observe Only" kind of.
thanks for all,
Yesterday I jumped from the bridge down to the salon deck on my boat, rather hard. The GPU started up. Spooky.
