So much of flying is about checklists. I have been surprised to learn just how many checklists you have to learn. Checklists about the fuel quality, the wings, checking the electrical system, checking the communications... And that's all BEFORE you even take off! I've been trying to think more about how to improve my checklist game.
I am a student of aviation, and a new one at that. Therefore, I make no claims to being an authority of any kind on the topics that I talk about. I am only speaking from my limited, biased perspective as a student who is learning and making mistakes. Therefore, none of what I say should be taken as fact or advice to be followed. Double-check me and let me know when I get it wrong.
