At the risk of being boring, can I please warn pilots against having their own plans for reseting C/Bs. Aircraft have lost control and crashed because pilots have made their own decisions about pulling C/Bs but not appreciating how the systems interact.

Similarly, I am always a little nervous when pilots have their own C/B maps and little ways of 'fixing faults'. Doing so on the ground with engines and systems off is one thing, but could lead to a mindset that might cause serious controllability problems in the air.

Also, different aircraft in the fleet may have breakers in different places, so having a personal note that says pull X18 and C27 to reset the toilet or whatever, might not be the right ones on the day and could get you into a bad situation.

QRH and Maintrol are the only sources we should follow for pulling or resetting C/Bs

PS
Breakers pop when they sense that too much current is flowing. Too much current running through a wire or item of equipment will cause overheating, melting and possibly fire - which is the very last thing we need !

If a breaker keeps 'nuisance' popping, put it in the tech log - it means there is an overcurrent problem somewhere which should be sorted out.
