Why is that?

I've had the same problem with my grabby guys, FO's need to be helpful but there's a line you don't cross. I guess they don't teach that at ATP or Expressjet.

Hey Rory, just hold down the red button of doom for 40 seconds and remind him that the priority is always left.

Rory you were like that as a FO so you will live

The FO can hit his button and regain control even after that. Don't confuse it with Autothrust disconnect.

Good thing there's an FO present during the flight to help clear up confusing concepts like this.

If AQP ever comes around, it's gonna hit some folks square in the ego.

Classic

I still want to know why FO's are taking the tiller over.

Apparently some captains are letting them taxi, that and the fact that andreas was spreading bad info about FCOM probably lent itself to the situation. Why do you think it's happening Tom B?

I naturally assumed it was warranted for some safety reason otherwise why would an FO do so.
