In a skidding turn, the gyro precesses towards the inside of the turn. After return on the aircraft to straight and level flight, the instrument shows a turn in the direction of the skid. In a normal turn, the gyro precesses towards the inside of the turn. The precession error is quickly corrected by the erecting mechanism. 2, record 3, English, - erecting%20mechanism
Record number: 3, Textual support number: 2 CONT
The only really tricky part of the attitude indicator is its erecting mechanism. When power (vacuum) is first applied to the instrument, the mechanism quickly erects the gyro spindle to plumb-vertical in order to align the artificial horizon with the natural horizon. In flight, the erecting mechanism continually compensates the gyro for precession errors in order to keep it aligned throughout the course of a long flight. The design of the erecting mechanism is quite clever. In an air-driven attitude gyro, there are "pendulous vanes" suspended from pivots attached to the lower portion of the sealed gyro housing, one vane for each exhaust port. The vanes are positioned so that, when the gyro is erect, each vane half-covers its associated exhaust port. If the gyro tilts so that its axle is not plumb, the pendulous vanes shift so that one exhaust port is more-than-half-covered and the opposite exhaust port is less-than-half-covered. The resulting imbalance of discharge air exerts a force on the rotor housing at right angles to the direction of tilt, causing the gyro to precess to the erect position. As soon as the gyro is erect, the pendulous vanes return to a balanced condition to remove the precessing force. Pure magic! The erecting mechanism can erect the gyro quite quickly at initial power-up because the gyro doesn’t exhibit much gyroscopic rigidity at low rotor RPMs. Typically, the horizon bar becomes level within the first 10 or 15 seconds, and then its oscillations (caused by precessional nutation of the gyro) are damped out within a minute or so as the rotor comes up-to-speed. 3, record 3, English, - erecting%20mechanism

[...] [La question] conduit à réaliser un asservissement permanent de l'axe du gyro à la verticale du lieu de la Terre survolé. Un tel système s'appelle système érecteur ou asservissement de verticale.

Dans ce tore, des billes circulent et sont très légèrement entraînées par des petits crochets fournissant des forces faibles. Quand le tore est «à plat», c'est-à-dire horizontal, les billes sont uniformément réparties sur le tore grâce aux crochets qui les font circuler en les poussant par l'arrière. 1, record 4, French, - syst%C3%A8me%20%C3%A9recteur%20%C3%A0%20billes

Principal Attitude Indicator Errors. Turn Error. During a normal coordinated turn, centrifugal force causes the gyro to precess toward the inside of the turn. This precession increases as the bank steepens; therefore, it is greatest during the actual turn. The error disappears as the aircraft rolls out at the end of a 180 degrees turn at a normal rollout rate. Therefore, when performing a steep turn, the pilot may use the attitude indicator for rolling in and out of the turn, but should use other instruments(VSI and altimeter) during the turn for specific pitch information. 4, record 5, English, - turn%20error
