Notice that there is no knob to set the heading of the DG [directional gyro] to match that of the compass. Why? Because it is slaved. Slaved? Back in the tailcone of the aircraft, away from all ferrous metal, is a magnetic compass. The output of this compass is electrically "enhanced" and amplified through a "flux gate"... This signal is fed to the HSI to drive the DG portion of the unit. What this means is that the reading is very accurate, not subject to the vagrancies of the regular magnetic compass, and is constantly being corrected for drift. On some aircraft, this signal is also used to slave the ADF heading card. 2, record 1, English, - corrected%20for%20drift

Déplacement d'un gyroscope corrigé. Dans le cas d'un gyroscope corrigé pour la dérive apparente due à la rotation de la Terre, on applique une correction de 15° sin latitude par heure à l'écrou de compensation de latitude. 1, record 1, French, - corrig%C3%A9%20pour%20la%20d%C3%A9rive

Description et fonctionnement du gyrolaser [...] sources d'erreurs et solutions apportées [...] dérive de l'onde stationnaire (onde bloquée dans la cavité et qui est toujours en rotation même si la cavité reste immobile) [...] solutions apportées : on élimine la dérive de l'onde stationnaire en utilisant des cavités où deux écoulements de gaz se font en sens inverse, par exemple avec une seule anode et deux cathodes placées sur les 2 côtés opposés d'un carré. Ainsi les mouvements gazeux se compensent et la dérive est presque éliminée. De plus, on utilise un dispositif électronique supplémentaire qui mesure et compense la dérive résiduelle de sorte que seules des perturbations imprévisibles peuvent engendrer une erreur systématique. 3, record 1, French, - corrig%C3%A9%20pour%20la%20d%C3%A9rive
