fokker I'm not sure what it has to do with CRM...
Going off the thread a little, so shoot me...
I do agree with you in disliking the term "co-pilot". A large transport aircraft requires two pilots. They are appointed as Commander (or Captain) and First Officer.
I also dislike the phrase "
my co-pilot" in W/A PA's. In general the sort of phraseology I use is "Ladies and Gentlemen, on behalf of ............... Airways, I'd like to welcome you aboard this flight to ................ My name is ............., I'm your captain today, and with me on the flight deck is my colleague, (S)FO ............. Looking after your safety in the cabin are ................." etc. etc.
Not saying this is right - it's merely the sort of wording I feel comfortable with.
