The report did say this incident started with an A/T message or disconnect which by itself is not a big deal but followed by an ARINC smoke or avionics smoke message, this situation warranted a return in my opinion. Had this been a real avionics bay fire, it wouldn't have seemed prudent after the fact to have waited for my nostrils or eyes to detect particulates.
Exactly. Why have a mechanical instrument to detect what one's biological instruments (nose and eyes) cannot if, when push comes to shove, you are only going to rely on the biological instrument. It makes no sense whatsoever.
Seriously, if you are not going to believe your instruments, why have them.
