B737NG Packs & Apu bleed
Dear all,
I am new on aircraft. I checked documents and saw the real procedures in the cockpit. But I haven't decided on one thing yet which is very simple.
Is there a flow to follow when both packs off, iso valve open and apu bleed off and we want to operate the packs with bleed air. In which order we should configure the switches and what's the logic behind that ?
Do you operate firstly the packs auto then apu bleed on or vice versa or mixed order ?
Thanks
