Definition#
The rudder is a movable control surface attached to the trailing edge of the vertical stabilizer (fin). It controls yaw — the rotation of the aircraft about its vertical axis.
Why It Matters Operationally#
The rudder coordinates turns (preventing slip or skid), corrects for crosswinds during takeoff and landing, and manages asymmetric thrust in multi-engine aircraft if one engine fails.
