I hope no eager beaver CP's are reading this and think their SOP's need a revamp and tweaking update. There could be an endless list of things that people could dream up where they fall into the category of 'I wouldn't do that just incase something else goes wrong.'
I did come across a training captain from a neighbour airline whose personal opinion was to teach not setting the park brake when 'line up & wait' on the runway. Why? The brakes might stick on and you block the runway. Like I said the list could be endless if you let your imagination go wild.
