SaturnV
First and foremost, I have no more knowledge of these systems then the village idiot. However, I am frustrated this morning after almost two years of intriguing and well-reasoned discussion to see claims that perhaps no one was on deck from 2:10-2:15, when there is at least one (FPV), if not possibly more events in the ACARS messages indicating crew action during this period. (I am referring to the PRIM and SEC shutdowns).
So all I am really asking is to contrast the speculation that no one or only one person was in the cockpit, with the ACARS messages. I cannot as I do not understand how ACARS generates the two messages---Captain and F/O.
If one selects the Flight Path Vector function and it is unavailable, does this generate messages for both?
Can you select the FPV of one seat from the other seat?
If the answer to either one of these question is yes, then the one person theory is possible, if the answer to either one is no, then it is false.
