When at a recent working group at Boeing, it was put to them that it would be a good idea to have a standard terminology.
We pointed out that we have Cockpit, Flight deck and control cabin and to give it one title, to stop any confusion.
They said they would go away and look at it and try to have a standard name.
This is with the B757 and hopefully would migrate onto the other aircraft.
I wonder what name they will come up for the Airfix Kit they are to build, meaning the B787 who don't get my English humor or wit.
