Its a sticky wicket for sure, when I flew 130's it usually wasnt a problem as procedure is something that is beat in you from day one of UPT.... but I have had that problem now and again, and usually a nice easy conversation with the AC would clear things up. In the airline world I found that every CA had his way of doing things... some straight by the book... others would decry... "when this was still "Command Airways"...we did it like this and I dont care except on checkrides..... generally I'd go with the flow unless safety was compromised and to be honest the few times a capt wanted to do something that was pushing the limits of SOP's he always told me what he was gonna do and why..... A couple times in a rush at Kennedy I questioned a young CA about something and both times he admitted to having used old procedures.....etc.
Id be real careful about running the the CP. Exhaust other avenues first then if nothing else works.. you MIGHT consider that.
