QRH
Have a look at the AIR ENG 1 + 2 BLEED FAULT QRH procedure. Also some aircraft have the bleed OEB others, not. Airbus says do the ECAM first then the QRH, in certain situations may be better to do the QRH procedure then to the ECAM , first. If you agree(?)
Bear in mind Airbus has changed the QRH procedure.
There were flaws in the dual bleed procedure, and unecessary emergency descents with dual bleeds that had a bleed reset.
Interested also a critique of the Airbus procedures. As we are trained to do the ECAM first.
