Checklists - query
I'm curious, is it acceptable to do checklists while flying (and on the ground) entirely from memory? At a PPL level at least.
I've always been told to use the real physical checklist as a reference, which is fine by me, but after watching some vids on youtube I get the idea that a lot of pilots don't really bother with double-checking anything by cross-referencing the checklist. Is this common practice after you are familiar with the aircraft?
Apologies if this is the wrong section for this question.
