The heading indicator(HI) uses the principle of rigidity in space for it's operation. The gyro is mounted such that it registers changes around the vertical axis only; i. e. direction changes. The compass card attached to the gyro appears to the pilot as though it is turning. In reality, it and the attached gyro are remaining rigid in space, while the aircraft and case turn about the gyro. The HI is not automatically synchronized with the magnetic compass. It must be set to the compass heading while level on the airport surface prior to take-off. 13, record 2, English, - directional%20gyroscope

Le conservateur de cap, également appelé directionnel, est un gyroscope libre dont l'axe est orienté horizontalement selon la direction qui lui a été assignée lors de sa mise en rotation. Cette orientation sera prise pour référence horizontale. En choisissant le nord magnétique comme référence, cet appareil indiquera le cap magnétique de l'avion.

Le conservateur de cap, ou gyroscope directionnel, est l'un des trois instruments à gyroscope. Aligné avec le compas, il donne une indication précise et stable concernant le cap magnétique de l'appareil. Le conservateur de cap constitue une aide importante car le compas est sujet à des erreurs causées par l'accélération, la décélération et la courbure du champ magnétique terrestre, particulièrement sous les hautes latitudes. Il arrive fréquemment que le compas oscille; il est particulièrement difficile à lire dans les turbulences ou pendant les manœuvres. Fonctionnement. Le gyroscope du conservateur de cap pivote dans un plan vertical. Une carte comportant des caps maintient son orientation lorsque l'avion tourne. Le mouvement apparent de la carte donne au pilote une indication précise et instantanée du cap de l'avion et de la direction dans laquelle il tourne. La carte est marquée de 5 degrés en 5 degrés, avec une indication chiffrée tous les 30 degrés et les points cardinaux repérés par N, S, E, O. 11, record 2, French, - conservateur%20de%20cap

Angular rate gyro accuracy is characterized by two parameters: scale factor and drift. The scale factor describes the capability of the gyro to accurately sense angular velocity at different angular rates ... Gyro drift characterizes the ability of the gyro to reference all rate measurements to the nominal zero point. It appears as an additive term on the gyro output, so any actual drift away from a given or predetermined value will cause the angular errors to accumulate. 3, record 5, English, - gyro%20drift

The free gyro... can be converted to a directional reference by remounting its case with the spin axis horizontal and the indicator axis vertical. The indicator will then give the airplane's heading. Gyro drift is countered by slaving the instrument to the Earth's magnetic field, via either a separate magnetic compass or a flux valve device. 5, record 5, English, - gyro%20drift

The gyrosyn compass combines the functions of both the directional gyro and the magnetic compass. It provides stable compass headings in rough air, is north seeking like a magnetic compass, but is free from northerly turning error and oscillation. It does not precess and, therefore, does not require resetting as does the directional gyro. The gyrosyn compass system incorporates a flux valve that senses the earth’s magnetic lines of force through electromagnetic induction. 6, record 9, English, - gyromagnetic%20compass

As a CME [Coronal Mass Ejection] hits the magnetosphere, the compression of the magnetic field produces an increase in the field measured at ground level. This gives a characteristic rise in the field and is known as a Sudden Storm Commencement(SSC). Not all SSCs are followed by auroral activity, but it is a good early indicator. If the solar wind speed and IMF [Interplanetary Magnetic Field] direction are favourable, the energy in the magnetosphere will gradually build up into a large storm, with the magnetic field decreasing and changing rapidly. 2, record 14, English, - sudden%20storm%20commencement

On small aircraft like the Cessna 182RG, the pilot sets the heading indicator to coincide with the compass before takeoff and resets it periodically during flight to make sure that it remains in sync with the compass.

"Set" and "reset" express the same reality except for the time aspect and are not real synonyms. However, because of the necessity to periodically and continuously "reset" the gyros, one could say that the pilot "resets" the instruments in flight as well as he "sets" or "resets" them before take-off, referring to the last in-flight setting operation. "Reset" would be more appropriate for in-flight setting operation. 4, record 16, English, - reset

Gyroscopic precession. The reaction of a gyro when a force is applied to the spinning wheel. 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. 2, record 19, English, - precession%20re%2Dadjustment

Erreur de précession. Les forces de friction présentes dans le système gyroscopique engendrent la précession. Cette précession occasionne un «glissement» ou une «dérive» d'environ 3 degrés dans la lecture de l'instrument et ce, à toutes les 15 minutes. Le gyroscope est aussi sujet à la précession apparente. L'inertie gyroscopique garde le gyroscope fixe dans l'espace de sorte qu'il ne bouge pas par rapport à l'espace. Cependant, la terre qui tourne en dessous du gyroscope donne à ce dernier un mouvement apparent par rapport à la terre. La rotation de la terre cause une dérive apparente, ou précession, qui varie avec la latitude [...] L'erreur de précession, à la fois mécanique et apparente, doit être corrigée à intervalles réguliers, c.-à-d. toutes les 15 minutes. 2, record 19, French, - correction%20de%20l%27erreur%20de%20pr%C3%A9cession

Record number: 20, Textual support number: 1 CONT
The free gyro... can be converted to a directional reference by remounting its case with the spin axis horizontal and the indicator axis vertical. The indicator will then give the airplane's heading. Gyro drift is countered by slaving the instrument to the Earth's magnetic field, via either a separate magnetic compass or a flux valve device. 3, record 20, English, - slaving

Sur les petits appareils comme le Cessna 182RG, le pilote règle le conservateur de cap pour qu'il coïncide avec le compas avant le décollage, et le réajuste périodiquement pendant le vol pour être sûr qu'il reste synchronisé avec le compas. Le conservateur de cap dérive parce qu'il est basé sur un gyroscope, sujet avec le temps à la précession. En règle générale, le conservateur de cap ne doit pas dériver de plus de 3 degrés toutes les 15 minutes. Les appareils plus importants sont équipés de conservateurs de cap asservis qui maintiennent l'instrument correctement aligné avec le compas. 3, record 20, French, - asservissement
