Switching AP on Control Transfer
Does anyone know of any benefits of switching the Autopilot over to the side of pilot with control when control is handed over for short periods of time i.e. washroom breaks etc.? I'm talking here specifically about Airbus and switching between AP1 and AP2.
Are there any threats associated with flying the aircraft with the offside AP in control. Obviously it is recieving all it's data from the offside sensors and computers, and the threat here is that if there is a discrepancy between the two sides. But other than that any others? One would assume here that during cruise there are no major discrepancies, or that they've been sorted well before control is handed over.
