All this extra callouts nonsense stated at one airline where I worked, when the first Airboos arrived on the property.
Then, when these folks upgraded to the next airplane (TriStar) it was...silence once again.
One First Officer complained that his 'new' Captains on the TriStar told him to 'shut up' when the young guy tried to bring his Airboos callouts to the TriStar fleet.
The L10 fleet manager, having a limited sense of humor, sent the youngster straight back to the Bus...where he remained.
Ahhh, silence once again.
