I admit sometimes I waste too much time and energy to find out quite irrelevant things.
However, in doing so, I learn a lot of relevant stuff. And I like doing it.
I know of many very good pilots who don't know the airplane as well as I do.
In my opinion, in a computerized airplane, the system descriptions should always say which computer or hardware compares valuses, detects discrepancies, or controls automatic logics of a given system, etc...
Anyway, I think that this is a good question to ask:
Why do we have to BARO REF..... X CHECK when an FCU channel is lost?
We do it every time we change the setting, right? (as per SOP and if we use good cross cockpit communication). It is kind of insulting. Does the ECAM mean that we don't xcheck the baro settings?
Or is there another reason to be extra careful? Can the setting revert to STD on its own, or something like that?
