I'm more interested in what the FMA says, not the MCP.
That is what the call should be: if any. The FMA. PF announces that you've made the selection after you see the FMA. PM then verifies it by glancing themselves.
More importantly, in some companies they call all changes, even automatic ones. I as PM called them out and PF said"check." (what else.) However, the FMA was an unhelpful one. I called it again and received the same response. I called it again in the hope the hint would ring a bell. The response was, "check, i heard you the first time." Unfortunately, VNAV PTH at SID cap altitude was not what we wanted when ATC had requested us to climb. But the guy had pushed the VNAV button, so that must be alright then. Ya!
Being a parrot is not being a pilot; neither is being a trained monkey. The combination of the two is deadly.
