Variations between companies depending on how many Aux pumps are fitted and requirements for electrical load minimising for engine start.
e.g. GE engines, 1 Aux pump on the No4 system, pre-start:1,2,3 ADPs to Auto, No4 Aux pump on; after-start: all ADPs to Auto.
GE engines, 2 Aux pumps, pre-start: 1 and 4 Aux pumps on, 2 and 3 ADPs to Auto; after-start: all ADPs to Auto.
RR engines, 2 Aux pumps, pre-start: 1 and 4 Aux pumps on, 2 and 3 ADPs OFF; after-start: All ADPs to Auto.
and so on...
