I agree, HaveBlue
that is a much more reasonable figure.
Whatever the correct number (I could not find the other thread) it is easy to imagine the need to dump.
is going to burn quite a lot of fuel and you need to keep in mind that the flight was planned to arrive at destination with enough fuel to meet flag rules for alternate, reserve, and any other needs. So by the time it is in the vicinity of ANC
it is still pretty heavy.
I'm not a 747 pilot and don't have actual numbers but there are some generalities that need to be considered here. If the pilots had a problem that required them to go to the nearest suitable airport (or some such rule) while it is pretty serious, it does not wipe out all the other safety rules. They cannot begin an approach into ANC
at a weight that would not permit them to do a missed approach or a rejected landing with an engine inoperative. Fuel dumping sees a likely option under the circumstances.
I'm curious who it was that had the power to order this pilot to write an essay on anything. I believe that I'd have changed the rules a bit and written one on the environmental damage caused by dumping ALL
my fuel plus three hundred dead human bodies in the ocean.
It is called "captain's emergency authority"
Happiness is not seeing another trite Ste. Maarten photo all week long.
