Don't forget these testing officers are no different to any other serving IFR line pilot. They are only there to test (because they have jumped thru the hoops) for a certain 'standard' where the regs/rules are concerned, not so much how you go about achieving that unless yr in a C&T (CAR217) environment where SOP's are or should be strictly adhered to. I reckon everyone does things differently in the cockpit especially in the chrt world single pilot. As long as it works for you & you get the job done safely.
