Some comments are made in the judiciary report on the BUSS and they're not that
positive
I lack the french language so can not comment on that one.
AFAIK BUSS activation comes with increased workload (e.g. ALT LAW and manual outflow valve control)
... It is also said that its activation is definitive. You said
otherwise
here. Do you have more info ? I can't find anything in the
documentation.
on ground and in early simulator experience (but could be sim issue) it is reversible by selecting any ADR to ON.
Procedural it will be difficult to revert to the normal display because one selects the BUSS when ALL ADR FAULT or in case of ADR DISAGREE.
Without displayed air data information it will be a gamble to reselect an ADR with valid information.
