I found it not only invaluable but also very fascinating to read beyond what my Jeppesen had on ADM. I think that the importance of ADM goes well beyond a duration of a flight and during all the on the ground decision making that has to do with that flight. It is kind of weird that ADM is just a chapter at the end of a PPL handbook, but, I feel like the importance is not very emphasized. CFI's your thoughts? Also I've heard that most pilots have A-type personalities, but I don't have an A type personality, I am more like a C or D type. What other resources are there to direct me to find more info about ADM?
