Two consecutive cycles of 2 min duration maximum, plus one additional cycle of 1 min, with a run down to zero N3 between each cycle, or
One 5 min cycle.
Wait 30 min after the last cycle to allow the starter to cool.

Min Feed Tank Fuel Quantity before pushback
4000kg
Before pushback, if at least one fuel transfer tank is not empty, ensure that the fuel quantity in each feed tank is more than 4 000 kg.
Note:
If the fuel quantity in one or more feed tanks is less than 4 000 kg with fuel available in transfer tanks, perform an automatic ground transfer using the AUTO GND XFR pb-sw to adjust feed tanks fuel distribution.
