Hi Guys, removing all AC is not really needed... just select Standby Pwr on Bat and the Standby busses will be fed from the Battery and Inverter.
Regarding the gear down case, it's true the
fuel flow is 1,4 times greater, but in a diversion you'll have to maintain 220 knots instead of normal speeds, thus the almost twice total consumption.
Ciao, LEM
