Oh, yes and when your a/c is burning and you want to get the thing on the ground pronto, you cant, not allowed. Why? Well the Emergency checklist (Law not an SOP) says you cant, as you are above the max landing weight. So land now or die waiting to get down to landing weight. That is the choice.
Say what?? Surely that sort of situation (onboard fire) would be a Mayday, in which case (assuming that aircraft Mayday procedures are the same as marine ones, which I know about) the commander's priority will be the preservation of the lives of those on board the aircraft rather than rigid adherence to SOPs?
