Its primary goal is to counteract the typical Dutch roll aerodynamic mode of many aircraft. It also helps keep turns coordinated by automatically providing the … Dutch roll is a type of aircraft motion consisting of an out-of-phase combination of "tail-wagging" (yaw) and rocking from side to side (roll). This yaw-roll coupling is one of the basic flight dynamic modes (others include phugoid, short period, and spiral divergence). This motion is normally well damped in most light … See more In aircraft design, Dutch roll results from relatively weaker positive directional stability as opposed to positive lateral stability.
