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

... the TSB [Transportation Safety Board of Canada] analyzed specifically the aircraft steering system, while not ignoring the other factors mentioned above, although no indication was found that they could have contributed to the occurrence. To steer the aircraft on the ground, the pilot in the left seat uses the nose-gear steering wheel on the console to the pilot's left. During take-off and landing, directional control of the aircraft is maintained solely by the rudder. The aircraft's ground steering system comprises several components, including the nose-gear steering wheel, a system of cables and pulleys, and a steering control valve fitted to a nose-wheel steering cylinder, which is attached to the nose-wheel strut. The cable and pulley system links the steering wheel to the control valve. When the pilot turns the steering wheel to the left or right, tension is applied to the cables connected to the pulley on the steering control valve. This action determines the direction and the deflection rate of the nose wheel by allowing hydraulic fluid to enter one side or the other side of the nose-wheel steering cylinder; the steering cylinder then deflects the nose wheel through a system of gears.  3, record 2, English, - aircraft%20steering%20system

[...] le BST [Bureau de la sécurité des transports du Canada] a analysé plus spécifiquement le système de direction de l'appareil sans toutefois négliger les autres facteurs mentionnés précédemment, ceux-ci n'ayant d'ailleurs révélé aucun indice permettant de croire qu'ils auraient pu jouer un rôle dans cet accident. Pour diriger l'appareil au sol, le pilote assis à gauche utilise le volant d'orientation de la roue de nez localisé sur la console à sa gauche. Lors du décollage et de l'atterrissage, le contrôle directionnel de l'appareil est maintenu uniquement par le gouvernail de direction. Le système de contrôle de la direction de l'appareil au sol est constitué de différentes composantes, dont le volant d'orientation de la roue de nez, un système de câbles et poulies, et un robinet de commande d'orientation monté sur un vérin hydraulique de direction du train avant, relié à la jambe de la roue avant. Le système de câbles et poulies relie le volant au robinet de commande. Lorsque le pilote tourne le volant vers la gauche ou la droite, une tension est appliquée sur les câbles reliés à la poulie du robinet de commande d'orientation. Cette action contrôle le taux de braquage et la direction de la roue de nez en permettant au fluide hydraulique de circuler d'un côté ou de l'autre du vérin hydraulique de direction du train avant; ce dernier fait tourner la roue de nez par le biais d'un système d'engrenage.  4, record 2, French, - syst%C3%A8me%20d%27orientation

A fixed trim tab is one that can be adjusted on the ground but cannot be adjusted in flight. This type of tab is usually a sheet-metal plate attached to the rear of the control surface and extending to the rear of the trailing edge. If the pilot reports that the airplane will not fly straight and level at cruising speed, the appropriate tab is adjusted on the ground by bending a rudder tab to the right or left, and bending the aileron and elevator tabs up or down, depending upon the correction required.  2, record 3, English, - fixed%20trim%20tab

The left rudder would operate normally since the RH [right-hand] nosewheel steering tube assembly could still operate in the compression mode. Furthermore, in this condition, the automatic centring action of the nose gear as the aircraft lifted off would have resulted in the application of two to four degrees of left rudder deflection. This is due to the left-hand rudder centring spring taking up the slack introduced in the right-hand rudder cable by the right-hand rudder pedal being moved aft of its normal position due to the shortened length of the RH nosewheel steering tube assembly.  2, record 4, English, - centering%20spring

La commande de direction vers la gauche aurait fonctionné normalement puisque l'ensemble de droite des tubes d'orientation du train avant pouvait toujours fonctionner en mode de compression. Qui plus est, dans une telle situation, le centrage automatique du train avant au moment du décollage aurait provoqué l'apparition d'un braquage de la direction de deux à quatre degrés vers la gauche. Ce phénomène est dû au fait que le ressort de centrage gauche de la direction a compensé pour le mou apparu dans le câble droit de la direction à la suite du déplacement de la pédale droite du palonnier en arrière de sa position normale à cause de la longueur moindre de l'ensemble de droite des tubes d'orientation du train avant.  2, record 4, French, - ressort%20de%20centrage

In the last lesson we learned to turn using the ailerons to roll the aeroplane into a banked attitude, and the elevator to raise the nose slightly to maintain the required lift by increasing the wings’ angle of attack. But the rudder plays an important part here as well. As we roll into the turn adverse yaw will try to point the nose in the wrong direction and so we will need to apply rudder in the direction of the turn as we roll. Once we are established in the turn the design of modern ailerons is such that adverse yaw is greatly reduced and we may not need to continue to apply rudder to keep the ball in the middle.  1, record 8, English, - apply%20rudder

The other component of the turn coordinator is the inclinometer, better known as the rudder ball. This is a black ball in a liquid-filled, curved and sealed tube. The ball is there to help keep your turns coordinated. That is, to prevent the airplane's tail from skidding to the outside of a turn or slipping to the inside. In a skid, the ball will roll opposite to the direction of the turn; In a [slip], the ball moves to the inside of the turn. To prevent slips or skids, pilots are told to "step on the ball, "meaning apply pressure to the rudder corresponding to the ball' s location. Ball left?
