Totally agree with Don's statement--he's a pilot, and those guys have to be very well organized!
We also record, in our log book, every detail every time we leave the slip: engine hours, destination, time we left and got back, and how each motor ran. Not only is this a great diagnostic tool (when a problem develops later on), it provides a LEGAL document showing wnen and where you were if some slug tries to blame a problem on you, (Don't laugh; it's happened.)
I do one other (anal) thing: I made a list showing where most of my tools, spare parts and repair stuff (like duc tape, fasteners, gasket material, etc.) is located. I call it my Inventory List, and it saves hiurs of searching for things! The list began when we on the hook one day with nothing to do.
