Airbus Cockpit question.

If you look at the left side of the glareshield panel in the picture below, there is a button marked “Side Stick Priority”. Can someone explain what its for please?
I thought myself its to do with the change in Pilot Flying during the flight but I’m not sure.

There is no practical application for the dual input scenario as the proper technique is to use the takeover pushbutton instead. What it is there for is to advise if PNF is making subconcious inputs while covering the controls during take off or landing. On an aircraft with conventional controls the only indication is the other pilot restricting control input 😮

If the takeover button was not pressed but the other pilot operated his joystick then the aircraft will follow a path according to the algebraic sum of both joysticks and the synthesised aural ‘dual inputs’ will sound.

Sorry to step in the Com forum from GA like that, but I can’t help to wonder what would be the actual result of a dual input and in what sort of situation that functionality would actually come useful….

If one moves the stick to the left and the other one to the right, the aircraft carries on straight? Would you want that?

Thank to unravel the mystery 😉

If one guy/gal takes over from the other then the button will illuminate on the side that has been taken over showing an arrow pointing to the other side. There will also be an aural synthesised voice call out of ‘priority left/right’. This is achieved by the pilot who wants to take over pressing (and holding down) his takeover button on his sidestick. It remains in place until he releases the button or 30 seconds when control latches to his side.

If the takeover button was not pressed but the other pilot operated his joystick then the aircraft will follow a path according to the algebraic sum of both joysticks and the synthesised aural ‘dual inputs’ will sound.
