When tilting the aircraft to the side, it does not act realistically as it did before.
So this is what I think BIS did:
People were complaining about "auto-rudder" when using airplanes. When you start ArmA 3 by default you have mouseleft/right assigned to something called RIGHT TURN AND LEFT TURN in options. This bind makes it so not only do you ROLL but you also use your rudder to YAW. Thus making it seem like the airplane sways BACK AND FORTH after turning.
This could've been easily fixed by moving MOUSELEFT/RIGHT to something called BANK LEFT AND BANK RIGHT. But instead of BIS telling people to do this, they completely removed the turning physics from the game thus making it very unrealistic.
Please refer to the videos.
