I hear the "overloading the PM" argument all the time. I've never flown in Europe, but I've flown into some very busy airports here in the US (JFK, ORD, LAX etc.). Is the radio work that much different in Europe that the PM gets overloaded? Honest question.
I really can't recall a time that as the PM, I wished the PF would turn on the AP to reduce my workload.
