DFC:
Would you climb to the cleared level and wait for the asel to be set also?
Off course not. I would set the altitude myself or wait those 10 seconds with the climb. I'm sure you are just asking this as a provocation and you would well know the answer to that question.
Waiting for the PF turns to heading 230 and sits there and after doing some other task the PM sets FL230 in the asel window and direct ABC in the FMS.
Or maybe the PF
with AP engaged sets 180 in the speed window when told to turn south (done it myself a few times too, say on already on heading 220 with a speed of 220). Point being that false MCP selections can always be made, and thats why we are 2 to crosscheck it - with or
without the AP engaged.
What you are describing is no different from the PF who because the PM is busy with a frequency change reaches over and retracts the flap. The SOP crosschecks are there for a reason.
Absolutely not. By communicating what I set, I give the PM the chance to correct me if I am wrong. And by starting a turn I also give him the chance to say, "hey it was 080 in a left turn not a right turn" or whatever (an error that could also be made if the PF was manipulating the HDG bug with AP engaged).
Changing a configuration with out communicating and agreement (aka the call for, and check/action by the PM) does not provide a chance for the other pilot to disagree.
It's all a matter of common sense.
