As a non "operator", looking from the outside in, so to speak, I think the whole issue of low fuel levels and how you professionals "cope" and the difficulties that it brings with it actually comes down to experience.
Lots of experience.
The trouble is now, with foreshorted training designed to meet those training "targets" the flying hour/experience ratio is going the wrong way, IMO.
Please feel free to correct me as you feel fit!
