It's interesting to see how different pilots fly. I suspect we tailor our
usage to our physiology and wants.
I just don't need relief as often as many others, but conversely, I need fluid
and food much more often. As a result, I fly with water bottles and snacks. I
haven't done a poll, but I suspect many diabetic pilots need occasional
snacks to keep their blood sugar somewhere near normal.
I don't think a six hour flight would be out of the question for me. But a
601XL I decided upon, and a 601XL I'm building. When this airplane is flying,
I'll look again and see what I think my next project should be.
