Yes, D, but to go from 1800kg total to 600kg total would take some significant errors, don't you think? Perhaps you should be sure before you 'commit' that you
will be able to land first time? Best not to get yourself into that 'statistical quagmire' you describe. We are beginning to go down the 'what if I get 2 emergencies' line and aviation is NOT designed to cater for that. As someone said elsewhere, if you are worrying yourself about that scenario, should you be flying at all?
However it is not uncommon these days.
- what is 'not uncommon'? 600 kg total, 1200kg total or what? A CMR of 1800kg should not get you anywhere near any of those.
The aft pump feed is only relevant during the g/a and accel. Once you either slow down or put the nose down for landing...................... In any case, providing they can find fuel in the tank, the motors will run without tank pump pressure.
Half of this problem (737NG) comes from the 'factory' (high)
LOW setting at 907kg (discussed in another thread). Any yellow warning anywhere and people start twitching. 1810kg is a lot of fuel in reality. 1200kg is equivalent to 30 minutes holding. The Classic does not call for any drills until below 453kg on any side, and the NG burns less.
