So Ops.A needs amending, for instance:
"This is a formal warning given by Fred of this aircraft" - doesn't have the same ring about it really.
Or try this one on:
"Fred you are not listening" - makes you really stand up and take notice.
I couldn't give two hoots about a title in everyday life, but in our job we have clearly defined roles and a clearly defined chain of command. There should also be clearly defined titles.
