I kept out of the debate on the prop level position on approach, as I haven't yet flown with a variable pitch prop. However, I will be soon, and the pre-landing (sic) checklist indicates prop - fine. Don't ask me to justify/explain it - its just there!
My original point was that I thought the usual mnemonic checks were unstructured, presumably derived from many moons ago, before we had more understanding of the human factors issues.
I was therefore wondering why such methods are still used. This also touches on the points raised by Chuck concerning training methods, i.e. we've always trained it this way, so let's keep doing it.
with thanks
