Why are we talking about "harnesses" in the BUMPFFITCHH check, and about "seatbelts" in the HASELL check?
And then BUMPFFITCHH itself. Why do you check mixture and prop (MP), then something else (F), then the fuel pump (F), two other things (IT), and then the carb heat (C). Why not group everything that's engine related with each other (MPFC), and have other groups for airframe (BUHH or even BUSH - S for seatbelts), flight controls (FT) and Instruments?
And that's not the only one. I find myself altering checklists, but also these mnemonics regularly to make them flow better, and to make them consistent with each other.
