Thank you Chuckles and others for saying in clear and concise terms what I meant but in my usual muddled way failed to say, ie a checklist is not a to do list!!
The company for whom I do some occasional work in PA31s has a rather neat laminated A4 sized checklist which is used for that precise purpose.
