Far out. I'm developing a headache. If we need this much debate over something as simple as whether we should be carrying a checklist, no wonder we're all lost on the rest of it. When I did my training, up to PPL you didn't need a written checklist, doing it from memory was ok. As soon as I started doing my CPL training, we were required to use a written checklist. Back then it seemed simple. PVT = no checklist. Commercial = checklist. Am I simplifying it too much..? Was I taught wrong..?
