IMHO this could not be right!
Example: you fly a turn at low bank angle lets say 5�, so you will need no
(or very less) aileron to hold the bank. (aileron = 0)
but at 5� Bank you have to use rudder to fly a correct(!) turn, and
rudder=aileron/ 2 = 0/2 = 0 != rudder needed.

As soon as the ailerons go to zero, the rudder should normally go to zero as well. The rudder does *not* make the airplane turn, and you should not hold any rudder at all in a normal turn once the bank is established -- the rudder merely compensates for adverse yaw from the ailerons (which isn't all that serious in most modern, general-purpose planes). That said, some aircraft do need a bit of top or bottom rudder to keep the ball centred at any given bank angle, but that's not to turn the plane, just to compensate for adverse yaw in the bank. Likewise, you may need to use some aileron to keep the plane from levelling out or overbanking, and in that case, you *may* need a bit of rudder as well, if the ailerons cause any adverse yaw.



All the best,
