[Screaming_Emu]

I always pre/post flighted with my student. The first few lessons I would have them do it and shadow them. Then once it was clear they knew exactly what they were doing I would help them by splitting the inside/outside. Then to keep them sharp I'd ask them random questions during the preflight. No matter what, I always did a 360 degree walk around at the end to check/double check the important stuff (not tied down, fuel caps on, oil qty, fuel qty, etc). Learned that one after I did a 150 mile x/c with the fuel cap IN the airplane instead of on it. Thankfully it was in a DA20 and not much (if any) got sucked out.
