My before checklist required me to ensure that park brakes are ON and blue HYD pressure in the tiny green band before push back. Most of the time there is a slight bleed off during transit to just below the green band.

Unlike the Boeing aircraft there is a AUX pump to ensure that is done but the Airbus does not have a pump u leave on before push back.

What does your policy require u to do . Do turn the BLUE Elec pump on ...get the needle in the green band and turn it off. Is there a allowable limit below and just let the EDP do it or what...

Thanks in advance for the answers

I think it is relevant if you are doing engine starts out of sequence. Have a look at external start procedure - think it mentions blue system if starting No 2 first. Normally, No 1 brings the Blue HYD up on start.
