I know this is an old topic, sorry, I’m searching for specific things and saw this.
Full control deflection is not common, but it does happen especially at slow speeds in adverse and gusty wind conditions. Control authority decreases with airspeed so the pilot will make large deflections of the controls at slow speeds, especially landings.
This is something that MSFS is terrible at simulating. It’s not remotely authentic or realistic. So, in the simulator, you have to be extremely precise on landing or you will over control. That’s wrong in the real world, but it’s how you fly the simulator as opposed to a real airplane.
