We have all these things we can say to the FO to get her to reconfigure the fuel tanks as the 747 burns down: "Fuel Low Stabilizer Left", "Fuel Tank to Engine", etc. But the -ER model has Aux fuel tanks as well, with corresponding EICAS messages FUEL AUX L and FUEL AUX R. There should be a "Fuel Low Aux Left/Right" voice command that prompts the FO to turn off the pumps.

Also, related, I think there should also be a "Fuel Low Stabilizer [Both]" (same for Aux) that prompts the FO to turn off both pumps. It's awkward to say "Fuel Low Stabilizer Left … (wait for her flow) … Fuel Low Stabilizer Right".

That gets messy.  It really best to control the fuel pumps manually in those situations.

The more voice commands you have the greater the chance of false detection.
