"ITS MY AIRPLANE"
No its not.Unless you paid for it yourself.
EXAMPLE
A new PIC (DEC) joined our company.He has 26000 hours including 5000 PIC on type.Worked for only one coy for 43 years (he was 64 at the time).Im the IP in the right seat just going through the motions of signing him off mainly getting him used to our SOPs.Upon leaving the runway, im awaiting his command to conduct the after landing items, but im not allowed to do this until he stows the speedbrake to indicate that we are now in taxi mode and have moved on from the landing mode (Boeing FCTM).This action never happens, and after a long taxy with lights blazing, flaps down, etc etc I give him a friendly "prompt" that the after landing procedure should be actioned now?.A very terse reply of "dont touch anything, its not safe", screams out from the left seat.OK.Upon giving him a debrief and asking nicely for his reason for the non-standard actions, he tells me."Its my airplane, im PIC.If I deem it unsafe for you to go heads down while taxying, not watching for traffic etc etc, YOU WILL FOLLOW MY COMMAND".
He is now advised that he cant invent his own SOPs and on his line check the next day, he will be expected to follow the comany SOPs, by lowering the speedbrake at the end of the landing roll, unless there is sufficient reason not to.(contamination or very dense traffic would be acceptable reasons, but these were not present on either sectors).
The following day he did the same thing.The very next day he was terminated due to willful non-compliance with SOPs, and of that particular story.......Pete the pirate.
