Further to #1182
IF THS is usually " 5 units Plus or Minus 2 units" .... But is seen to be outside this range ... THAT might make a Pilot suspect that something might be WRONG.
There were THREE pilots on AF447. ( Just ONE on the Sim )
" Our HEARING is the first SENSE to be shut down." #1136
I am not sure that this was known when a Potential Chief Pilot for a new Airline was being checked by our Fleet Manager was FAILED for failing to " Stop for an Engine Fire before V1... "
He was sent home.
( Some years later our Fleet Manager asked me if I felt that he had done the right thing.. With the THEN knowledge.. I felt that he had done the right thing. The FIRE Warning Had been close to the Potential Chief Pilot's left ear... And he had done NOTHING.
