Also, I'll suggest that around the world most simple piston engined flying is done without written checklists.
That is my experience. There is a requirement for basic piloting skills. That includes an instinctive understanding for what is required to execute a safe flight. I sure hope that for a competent pilot in a Tiger Moth, none of this would need to be written on a checklist.
Returning to this prang, what I can't understand is how a wrongly set trim caused such a kerfuffle. The trim on a Moth is not that powerful and is easy overridden. Something else happened here.
Very much agreed.
