Which outcome occurs when a commercial aircraft experiences a sudden, uncommanded rudder deflection at cruising altitude?

💡 Explanation

Dutch roll occurs because strong uncommanded rudder input excites a combined rolling and yawing motion which is positively reinforced. This oscillatory instability grows therefore because aerodynamic coupling induces a spiral rather than gradual return to equilibrium.
