But one of our F/Os just called "Go-around" in response to a GPWS terrain warning and it confused the whole show....they did a go-around rather than the escape maneuver.
That's why in my company the callouts by the Pilot-Not-Flying should be 'PULL UP' or 'WINDSHEAR', causing the respective recocery-procedure.
I had some similar expiriences in SIM-Training, if PNF calls for 'Go-Around', PF will in most cases call for a flap-reduction.
