... gyros and accelerometers have an offset, known as bias. The gyro bias for instance, shows itself after integration as an angular drift, increasing rise linearly over time(ramp)... To compensate for sensor drift, a process called augmentation is used, whereby gyro and acceleration errors are compensated by utilising other system states. For instance the angular drift error of a gyro after integration can be compensated, if true angular measurements are taken. Comparing the two shows then the gyro drift. Assuming that inertial systems are generally operated around an equilibrium position and thus linear acceleration integrates to zero over time, then attitude can be processed via gravitational acceleration, thus giving true angular measurements to compensate gyro drift. 1, record 1, English, - angular%20drift

Rigidity in space. The gyroscope resists turning. When it is "gimbaled"(free to move in a given direction) such that it is free to move either in 1, 2 or 3 dimensions, any surface such as an instrument dial attached to the gyro assembly will remain rigid in space even though the case of the gyro turns. The attitude indicator(AI) and the heading indicator(HI) use this property of rigidity in space for their operation. 6, record 2, English, - gyroscopic%20inertia

L'inertie gyroscopique, appelée aussi effet gyroscopique, constitue la propriété fondamentale des gyroscopes. [...] Il s'agit d'un principe selon lequel tous les objets résistent naturellement à l'accélération ou au changement de direction. (Par exemple, les occupants d'une voiture sont projetés vers l'avant quand celle-ci s'arrête brusquement parce qu'en raison de leur inertie, les corps continuent leur mouvement vers l'avant même si la voiture s'est arrêtée.) Lorsqu'on parle d'inertie gyroscopique, on fait allusion à l'inertie que possède un corps qui tourne. Tous les objets tournant autour d'un axe ont tendance à maintenir une orientation fixe, c'est-à-dire une direction de rotation et une position fixes, si aucune force n'intervient. En d'autres mots, un objet qui tourne a tendance à rester dans la même position. 2, record 2, French, - inertie%20gyroscopique

The attitude indicator(also called the artificial horizon or the gyro horizon) provides the pilot with an artificial horizon as a means of reference when the natural horizon cannot be seen because of cloud, fog, rain or other obstructions to visibility... The natural horizon is represented by a horizon bar on the face of the instrument. The attitude of the aircraft in relation to the horizon is indicated by a split bar or, on some instruments, by a miniature airplane.

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.

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 10, 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 11, English, - gyro%20housing

The attitude indicator(also called the artificial horizon or the gyro horizon) provides the pilot with an artificial horizon as a means of reference when the natural horizon cannot be seen because of cloud, fog, rain or other obstructions to visibility... The natural horizon is represented by a horizon bar on the face of the instrument. 4, record 16, English, - natural%20horizon

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 16, English, - natural%20horizon

The attitude indicator and heading indicator are based on a gyro's rigidity in space. Because a gyro resists being tipped over, it can provide a stable reference to the real horizon or to a specific direction. 2, record 16, English, - natural%20horizon

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 18, English, - turn%20error

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 20, English, - initial%20erection

The pitch and roll gyros were torqued by signals obtained by two Barnes mod IIA infrared horizon sensors. Gyrocompassing oriented the vehicle to an orbit plane yaw reference by detecting a component of the programmed pitch rate through the roll horizon sensor. The geocentric pitch rate(typically 4 deg/min, for a low-altitude orbit) was programmed as a constant torque to the pitch gyro.

The attitude indicator(also called the artificial horizon or the gyro horizon) provides the pilot with an artificial horizon as a means of reference when the natural horizon cannot be seen... The natural horizon is represented by a horizon bar on the face of the instrument. The attitude of the aircraft in relation to the horizon is indicated by a split bar or, on some instruments, by a miniature airplane... When the airplane noses up, the miniature airplane rises above the horizon bar, indicating a nose high condition. When the airplane noses down, the miniature airplane sinks below the horizon bar, indicating a nose down condition. When the airplane banks, the miniature airplane banks on the horizon bar and the pointer indicates the degree of bank on the index scale...

The gyroscope exhibits two predominant characteristics. Rigidity in space. Precession. Rigidity in space. The gyroscope resists turning. When it is "gimbaled"(free to move in a given direction) such that it is free to move either in 1, 2 or 3 dimensions, any surface such as an instrument dial attached to the gyro assembly will remain rigid in space even though the case of the gyro turns. The attitude indicator(AI) and the heading indicator(HI) use this property of rigidity in space for their operation. 2, record 29, English, - rigid%20in%20space

Le gyroscope a été imaginé par Foucault pour mettre en évidence le mouvement de rotation de la Terre. Son emploi repose sur ce principe de mécanique que lorsqu'un corps, qui n'est soumis à aucune force extérieure, est animé d'un mouvement de rotation autour d'un de ses axes principaux d'inertie, cet axe doit rester parallèle à lui-même si l'on vient à déplacer le corps d'une manière quelconque, tout en laissant l'axe libre de prendre toutes les directions. Si donc, on imagine qu'une toupie soit suspendue de manière à être soustraite à l'action de la pesanteur, et de façon que son axe de rotation puisse s'orienter dans tous les sens, il arrivera que cet axe conservera une direction fixe dans l'espace, quoi qu'il soit entraîné par le mouvement de la terre; [...] 2, record 29, French, - fixe%20dans%20l%27espace

Attitude gyros, technically called vertical gyros because of the orientation of their spin axis, do precess, but correction is applied automatically. All attitude gyros have an automatic erection system that drives the gyro back to vertical when it precesses. The erection system detects gravity by means of a pendulous sensor that in turn opens air blast vanes on an air-driven gyro or powers electric torquer motors to drive the gyro back to vertical when it precesses. 3, record 31, English, - electrical%20torquer
