dutch roll
- Definição1
- A combination of rolling and yawing oscillations that normally occurs when the dihedral effects of an aircraft are more powerful than the directional stability. Usually dynamically stable but objectionable in an airplane because of the oscillatory nature.

- Contexto
- The Dutch Roll mode is a lateral/directional oscillation of bank angle, heading and lateral acceleration, which is the result of sideslip and cross-coupling of the lateral and directional axes.
