Air pressure differential is the principle on which the vacuum driven gyro instruments operate. A vacuum pump run by the airplane engine creates a partial vacuum in the system. A filtered air inlet upstream of the gyros allows air to rush into the system causing the gyro wheels to spin. 3, record 1, English, - vacuum%20gyro

La pression d’air différentielle est le principe de fonctionnement des instruments gyroscopiques à dépression. Une pompe à dépression(ou pompe à vide) entraînée par le moteur de l'avion crée une dépression partielle à l'intérieur du système. Une prise d’air filtrée, située en amont des gyroscopes, permet à l'air de s’engouffrer dans le système et de faire tourner les roues du gyroscope. 2, record 1, French, - gyroscope%20%C3%A0%20d%C3%A9pression

The gyro, of an attitude indicator that is driven by a vacuum system, requires 4 or more inches of mercury vacuum to operate and 5 minutes to get up to operational speed.

The gyro instruments require a source of power to drive their gyros. This power is supplied either by the electrical system of the airplane or by a vacuum system that functions by means of an engine-driven pump or venturi... Electrically driven gyros were first developed for use in airplanes that flew at very high altitudes where atmospheric pressure was too low to operate a vacuum system. Alternating current from engine driven alternators or generators provides the power to the gyros. 1, record 3, English, - electrically%20driven

Horizon artificiel. C'est un instrument important du tableau de bord. Il permet simultanément de maintenir une assiette et de mesurer une inclinaison. Il n’ indique pas le taux de virage. Il est essentiellement constitué d’un gyroscope tournant à vitesse élevée dont la principale qualité est la fixité dans l'espace. Il reste donc fixe et le boîtier dans lequel il est contenu est solidaire du tableau de bord. Il doit être alimenté soit par dépression(pompe à vide entraînée par le moteur), soit électriquement. 1, record 3, French, - aliment%C3%A9%20%C3%A9lectriquement
