The tendency of a rotating body, when a force is applied perpendicular to its plane of rotation, to turn in the direction of its rotation 90 degrees to its axis and take up a new plane of rotation parallel to the applied force.  7, record 1, English, - precessional%20motion

Gyroscopic precession ... When force is applied to a gyro, the device reacts as if the force had been applied at a point 90 degrees from the point of actual application, in the direction of rotation. Precession affects propellers, which act like gyros, and gyro instruments. Its principle effect is on the heading indicator, which tends to drift over time.  8, record 1, English, - precessional%20motion

A gyroscope will not only resist being moved out of its vertical position, it will also generate force as it attempts to travel in large, circular patterns. These patterns are most easily seen with a spinning top. As the top begins losing its energy, it never simply spirals straight down in the same direction that it was originally spinning. As it destabilizes, it will always begin slowly rotating or precessing in a slow, even circle that is in the opposite direction to its normal spinning motion. These circular patterns are known as "precessional" motions, and they are another aspect of a gyroscope's movement that will occur either in air or in a vacuum and can be used to overcome gravity.  9, record 1, English, - precessional%20motion

If an airplane changes suddenly from a nose up to a nose down position, as is the case during the take-off roll in a tail wheel airplane, the airplane will yaw sharply to the left as the pilot shoves the wheel forward to raise the tail. The application of right rudder compensates for the precession tendency.  7, record 1, English, - precessional%20motion

Tendance qu'a un corps en rotation, sur lequel on applique une force perpendiculairement à son axe de rotation, de tourner 90 degrés par rapport à son axe de rotation, dans le même sens que la rotation, pour finir sur un nouveau plan de rotation parallèle à la force appliquée.  5, record 1, French, - pr%C3%A9cession

Si l'on applique un couple à un gyroscope en rotation, couple appliqué sur un axe différent de son axe de rotation, il réagit à ce couple de manière à amener son axe de rotation parallèle à celui du couple appliqué, et ceci par le plus court chemin. Ce mouvement est dit «mouvement de précession» lorsqu'il est provoqué volontairement, et «dérive» lorsqu'il est dû à un élément perturbateur.  6, record 1, French, - pr%C3%A9cession

L'usage fait donner des appellations différentes à cette composante de rotation instantanée [...] : lorsqu'elle est due à un phénomène déterministe et connu, on l'appelle «précession gyroscopique»; lorsqu'elle est due à un phénomène aléatoire, ou bien que l'on ne maîtrise pas, on l'appelle «dérive gyroscopique».  8, record 1, French, - pr%C3%A9cession
