Well in some operations/cultures in those 40 seconds the PM will probably have to set a missed approach heading, set a missed approach altitude, de-select and re-select Flight Directors whilst (maybe) responding to various other PF directives and random ATC comms.
His actions may not be limited to solely monitoring instruments and calling deviations.
Easy enough for both PF and PM to get distracted at inconvenient times, another case of "beautiful SIM script" Vs "all hell breaking loose" at times in the real world.
Surely a bit of redundancy isn't going to DECREASE safety?
Galdian, if the PM ends up being so busy and the Work Load so high at the latest stages of the approach I believe there are other issues that need to be addressed rather than debating the use of A/T ARM or Off. Redundancy is going to increase safety IF it does comply with the manufacturer’s guidelines.
