Als Ringelpiez wird in der Fliegersprache eine Drehung des Flugzeugs um das äußere Ende der Tragfläche, verursacht durch einen Bodenkontakt während Start oder Landung, bezeichnet. (de)
In aviation, a ground loop is a rapid rotation of a fixed-wing aircraft in the horizontal plane (yawing) while on the ground. Aerodynamic forces may cause the advancing wing to rise, which may then cause the other wingtip to touch the ground. In severe cases (particularly if the ground surface is soft), the inside wing can dig in, causing the aircraft to swing violently or even cartwheel. In their early gliding experiments, the Wright Brothers referred to this action as well-digging. (en)
