In the lessons topics I learn that when you bank the plane the aileron goes down at the side you turn and therefore drag increases and the wing drags behind and yaws the plane opposite to the turn.But the other aileron goes up. Shouldn't this also increase drag in the same amount?How can only one wing be affected?

Hi,When you bank, the aileron going DOWN is producing more lift (by changing the average chord line and thus the AOA). This is what creates more drag (induced) on that side of the aircraft, and thus the adverse yaw. The aileron going up actual "spoils" and reduces lift, thus reducing induced drag. While it adds some deflection/parasitic drag, it is not near the drag created by the down aileron. Aircraft with bigger ailerons, and ones with ailerons closer to the fuselage generally have more adverse yaw characteristics. Hope that helps!Damian ClarkHiFi Simulation SoftwareDeveloper of ActiveSkyhttp://www.hifisim.comhttp://www.hifisim.com/images/as2betateam.jpg

Is this covered somewhere in the FS9 documentation?I suppose that I had deflection drag in mind, andthat drag is equal on both wing but not the induced drag.If I understand things correct.

Hi,I don't think FS documentation goes into very much detail on the subject. I learned what I know about it through my private, instrument, multi and commercial tickets. Any good basic pilot training manual should do the trick.-Damian
