The yaw damper system's main function is to reduce undesirable aircraft oscillations by counteracting the yawing motion around the vertical axis ¹. The yaw damper system is used for ² ³ ⁴:

- *Dutch Roll Prevention*: The yaw damper system prevents Dutch Roll, a phenomenon that occurs when an aircraft experiences oscillating motions due to yawing and rolling.
- *Counteracting Engine Failure*: The yaw damper system helps counteract the yawing motion caused by engine failure.
- *Assisting with Coordinated Turns*: The yaw damper system helps the pilot make coordinated turns, which results in a smoother ride for passengers.
- *Slip Prevention and Ride Quality*: The yaw damper system applies corrections when it detects slips or side-to-side G-forces, resulting in a smoother ride.
