Selon les dictionnaires courants usuels, le terme «assiette» semble réservé au domaine de l'aéronautique et fait allusion à la «position du trièdre d'un avion par rapport au trièdre de référence terrestre» (Dictionnaire encyclopédique Larousse); le terme «attitude» est synonyme d'«orientation» et est réservé aux domaines de l'aérospatiale et de l'astronautique pour désigner la «direction des axes d'un engin spatial par rapport à un trièdre de référence (Dictionnaire encyclopédique Larousse). Dans la pratique, «assiette» et «attitude» sont cependant largement utilisés - abusivement diront certains - sur le même plan dans le domaine de l'aéronautique en parlant d'un avion ou d'un aéronef. 5, record 6, French, - assiette%20de%20l%27avion

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 7, English, - erecting%20mechanism
Record number: 7, 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 7, English, - erecting%20mechanism

The rotor of the air-driven gyro is mounted in a sealed housing. Filtered air is brought into the gyro housing through passages in the rear pivot, the gimbal ring, and the side pivots. The air then blows against the rotor through two angled nozzles on opposite sides of the housing. The circumference of the rotor is machined with dozens of little bucket-like cutouts which allow the airflow to spin the rotor like a waterwheel (but a whole lot faster). Having done its work, the air then exits through exhaust ports on the lower part of the sealed gyro housing, whereupon it is sucked out of the instrument case by the vacuum pump. 3, record 8, English, - gyro%20housing

The attitude indicator relies on the principle of gyroscopic rigidity in space--the rapidly-spinning rotor disk resists any attempt to disturb its orientation. Thus, the gyro provides a stable horizontal reference against which the pitch and roll attitudes of the aircraft can be measured. The "artificial horizon bar" on the face of the attitude indicator is mechanically coupled to the gyro inside, so it remains parallel to the natural horizon. The instrument's little "symbolic airplane" is fixed to the instrument case, however, so it follows the roll and pitch movements of the real airplane. Consequently, the relationship of the horizon bar to the symbolic airplane is the same as the relationship between the natural horizon and the real airplane. 5, record 11, English, - natural%20horizon

Gyroscopic instruments... Once the artificial horizon line is aligned with the natural horizon of the earth during initial erection, the artificial horizon is kept horizontal by the gyro on which it is mounted. An erection mechanism automatically rights the gyro when precession occurs due to maneuvers or friction. When the older-type gyro tumbles as a result of extreme attitude changes, the rotor normally precesses slowly back to the horizontal plane. Even an attitude indicator in perfect condition can give slight erroneous readings. Small errors due to acceleration and deceleration are not significant because the erection device corrects them promptly; nonetheless, the pilot should be aware of them... 3, record 13, English, - initial%20erection
