The vacuum-drive heading indicator is the simplest of many types of gyro-controlled directional indicators designed to provide stable heading reference.... Errors. The chief cause of precession, causing the card to creep or drift, is bearing friction. Normal movement of the gimbal rings produces friction, which is increased if the bearings are worn, dirty, or improperly lubricated. Other sources of precession error include unbalanced gyro components and the effect of the earth's rotation. The latter effect depends upon the position of the instrument in relation to the earth, and is not appreciable unless a flight involves considerable change in latitude.  1, record 7, English, - unbalanced

Le gyroscope est monté à la Cardan comme dans le cas du compas mais il n'est pas balourdé. Un détecteur d'horizon monté sur la caisse de tore délivre un signal proportionnel à l'inclinaison du moment cinétique; ce signal est traité et est envoyé dans un moteur couple d'axe cd qui crée un couple vertical ramenant le moment cinétique horizontal.  3, record 7, French, - balourd%C3%A9

Apparent precession. A free gyro that is not slaved to any earth reference(as the vertical and directional gyros and the gyrocompass are) will tend to maintain a fixed direction in inertial space, that is, with respect to fixed stars. Then as the Earth rotates, the angle between the axis of such a gyro and an arbitrary line on the Earth will change, and to an Earth-fixed observer the gyro will appear to precess.  1, record 8, English, - Earth%2Dfixed%20observer
