funny how mnemonics should make things easier and here we are discussing what they actually mean
is it not much easier and more logical to scan the panel left to right and check everything is the way it should be ?
If there isn't an undercarriage lever at all, chances are that the undercarriage will be down
Was taught to do it that way in the PFL checks and I find it easier than BUMPFHHing all the time
