Yup, planes have yaw, pitch and roll. Pitch is nosing up and down, rolling is rotating alongside the length of the plane, and yawing is using the tail to turn flat left or right.
Now, you absolute idiot, how many axes of movement does a mouse support? It moves alongside your table, so that's only two. Either you use two buttons for one of the three axes of movement (defeating the point of not dedicating buttons to plane movement) or you do the simplified control scheme of many other games and dumb down yawing to either non-existence or to be slightly applied whenever you roll, aiding in turns. Problem is, this yaw assist kills several plane techniques, like roll-pitch turns (the added unintentional yaw will crash you into the ground), and both no yaw and yaw assist will eliminate the ability to knife fly. It simplifies the movement mechanics, by making you less capable to control your plane than it is in reality, simply because you are too stupid to wrap your head around 3 axes instead of 2.
Also, precision movement isn't required for planes since the movement options are always very gradual. Turning in the air works by air drift and not by friction against a surface, and though lesser-than-100% application on the axes would be good for some techniques, if you are that deep into the stuff, you'd go for a flight stick anyways (or a controller using dual stick flight controls).
