WebDescription A Dutch roll is a combination of rolling and yawing oscillations that occurs when the dihedral effects of an aircraft are more powerful than the directional stability. A Dutch roll is usually dynamically stable but it is an objectionable characteristic in an airplane because of its oscillatory nature. Related Articles Stability
WebIn aviation, a phugoid or fugoid / ˈ f juː ɡ ɔɪ d / is an aircraft motion in which the vehicle pitches up and climbs, and then pitches down and descends, accompanied by speeding up and slowing down as it goes "downhill" and "uphill".
