So many think that it is OK to use a tongue to fly an airplane. Yack yack, constant chatter repeating the bleeding obvious
No, Sir!
Callouts have been developed through the years because in a team communication is essential.
Of course when everything goes well you could say they are superfluous. Even boring, maybe. But that's what keeps awareness up when things go to worms and are not obvious at all. If I'm busy with something else, I want my colleague to tell me of every change he's made in the cockpit. The callouts method
is the guarantee that will happen in bad times. Or when I'm tired. Or bored or distracted. I'm human, after all...
It doesn't mean I'm not using my brain or flying with my tongue.
It means I'm realistic and know and accept my limits.
Callouts help me, yes.
Repeating the obvious? Until you keep it obvious you keep it safe.
