Where I work, we also do ECAM actions first, then normal checklists and computer resets and then STS. Like Stuck_in_an_ATR.
BDM, your previous statement defies the whole purpose of a OEB as it supersedes relevant ECAM action for the MC or MW triggered. In case there's no OEB reminder you're, put it simply, screwed by applying ECAM first. Think hard bout it. That's why when you check list of applicable OEB for MSN you check their OPS status RED or White and most importantly if ECAM is affected. If it states Y means you won't have any clues indicating that this ECAM isn't applicable and misleading but OEB is. Now you tell me, are you still gonna do ECAM actions for the warning applicable to OEB?
