My own take is a middle way. In a place like a staging area, people around, etc. I will shut down to refuel, although a more positive approach would be to teach the first aid guy to hot refuel - he's just sitting around reading novels anyway. I certainly won't leave the cockpit for the convenience of the customer (in my experience, the most inconvenient solution is the safest).
Baffin island? As Newfieboy says, up there, and with similar places mentioned above, especially with a dodgy battery, it becomes more acceptable.
Just because you
can do it, doesn't mean you necessarily
should do it.
CRMI hat off!
