FFF,
I'm not against checklists as such ... just sweeping statements
However, on checklists .... I always seem to miss things when using a checklist that I don't when I ... well, don't! I have two hands, one holds the checklist, and the other donates a finger to mark progress down the list. The problem is that when said finger is removed to switch a switch or something, it invariable looses its place when it comes back to the list? Probably just me ... but it shows a checklist is not beyond the realms of missed items. In a simple aircraft, you can work around the cockpit, use mnemonics or just remember. I personally think checklists are best suited to two pilot operations where one reads and one checks. Mind you, I've not flown more complex types and I can see a checklist might be useful until familiar.
