Q. Getting out of your running aircraft isn't a real big deal. If you desperately needed to take a leak, say, I'm sure you'd do it, given a flattish pad and so on, for as long as it took.
Hot refuelling isn't a problem either as long as you take appropriate care (ie don't go splashing fuel onto hot bits of the aircraft).
Adding the two, why is it such a big deal to get out and self-hot refuel?
A. It isn't, as long as you take reasonable precautions (fire extinguishers, be aware of the wind, don't be stupid about it; i.e. shut down if you're not happy.
