BOAC, I think weīre saying the same thing but itīs not a question of what I want to call it. The point I was trying to make is that the words take-off is now only used by ATC when issuing a take-off clearance, and likewise only used by the FD when acknowledging a take-off clearance. In all other instances the word departure is used. ATC use the term departure in all cases with the exception of an actual take-off clearance. I simply thought that the same policy/logic would be applied by airlines in their SOPs and thatīs what sparked off my curiousity.
