All the OEBs I have seen before were always applicable before initiating the ECAM. Our QRH states: « The flight crew must disregard the ECAM procedure and/or Status of the Ecam alerts listed in the « Ecam Entry » field and must apply the QRH’s OEB procedure instead »
Now it’s a good time to be on A320 Family. No more OEBs in our fleet now except a simple one on the NEOs (OEB 57).
