Go ahead and prep your swamp land, I'm buying. It's an absolutely true statement.

Who starts engines at AA? The CA.
Who answers EVERY challenge on the T/O checklist (11 items?) The CA.
Who makes the PA to seat the F/As for takeoff? The CA.
Who chimes the F/As when we are cleared onto the runway? The CA.

Furthermore, most if not all airlines get their T/O data at the gate. We usually get it on pushback or taxi out. Meaning that the F/O is now heads down comparing predicted vs. actual T/O data - while we're taxiing.

I'm just getting warmed up... we could do this all night. AA has long been doing it this way, flying in the face of conformity and normal F/O duties at EVERY OTHER AIRLINE worldwide. All of this stuff results in a whole lot of stuff not very evenly split between both crewmembers. This results in slower than usual taxi speeds to get all the stuff done SAFELY.
