As Cpt I never had to take the controls out of any FO.
As FO I had to take the controls out of a CPT who was training to be a farmer...
I'm no better than any one of us dear friends, but my point is that I was a FO, so I know what an FO thinks... I remember my fears and limitations... that's the only difference between CPT and FO. We have been on the right seat.
Regarding Flight Controls, of course PF hands, feet and brain on the controls.
PNF talks on te radio with a nice and sexy voice, professionaly do the wonderful paper work that without it the airplane doesn't fly and with the corner of his/her eyes keeps on monitoring the beautiful job PF is doing.
If you fell the rudder is a bit hard, just say "easy on the rudder tiger".
Aren't we all the best Pilots on the world??? Of course we are... so just enjoy and fly.
Don't fight amoung each other... Save your energies to flight against Company Administrations that try to makes us comun office employes.
We are the Aviation Industry.
