But it seems that that's not fashionable in these supposedly enlightened times where CRM seems to be perceived by many as "lets all get along and have a lovely time" rather than as effective communication between the cabin, the flight deck and the ground.
Yup, the 'lets all get along' scenario will many times result in botched up actions.
Also this
"Evacuate, Evacuate...Hazard on left!"
is a very large trouble-prone idea.
IE: Specific doors are to be identified for evac use not just a casual reference to the left or right side of the airplane.
SQ and SV did this many years ago...and it worked perfectly, and our small airline does the same.
FD crew are told to identify the specific doors
to be used and SCCM's are trained likewise, if an evac is necessary.
It is
no good having pax slide down, only to be greeted by a burning or still-operating engine, close by.
