Directional stability refers to an aircraft's ability to maintain a straight flight path without undue yawing or side-to-side motion when subjected to external disturbances, such as wind gusts. This characteristic is crucial for ensuring that the aircraft can navigate effectively and safely, particularly during maneuvers or when encountering turbulence. A well-designed aircraft will exhibit good directional stability, allowing it to return to its original flight path after being disturbed.
