Remember when you were taught 'Straight and Level'?
Ignoring altitude, there were three elements to maintain. 1. Wings level. 2. Constant heading. 3. Balance(ball centered). If you can maintain any two of these, the other one will look after itself.
The ailerons are the most direct method of maintaining 'wings level'
The rudder is the most direct method of maintaining direction.(Preventing yaw)
The balance will then take care of itself, because, if you hold the wings level with the ailerons, and maintain direction with the rudder, the ball
will be in the centre.
