In other projects Wikimedia Commons. The heart of the AI is a gyroscope gyro that spins at high speed, from either an electric motor, or through the action of a stream of air pushing on rotor vanes placed along its periphery. But once they are started, that pendulous weight in the bottom will not pull them level if they are out of level, but instead its pull will cause the gyro to precess. To start with, they often have slightly more weight in the bottom, so that when the aircraft is resting on the ground they will hang level and therefore they will be level when started. Modern AIs don't have this limitation and don't require a caging mechanism. Volume 1". An adjustment knob, to account for the pilot's line of vision, moves the aircraft up and down to align it against the horizon bar. The stream of air is provided by a vacuum system, driven by a vacuum pump, or a venturi. Categories : Aircraft instruments Avionics Navigational equipment Technology systems.


  • 52 AVIONICS NEWS • SEPTEMBER While there are names such as, Attitude Gyro, Gyro. Horizon some basic aircraft instrument theory. The primary​. The attitude indicator (AI), formerly known as the gyro horizon or artificial horizon, is a flight instrument that informs the pilot of the aircraft orientation relative to Earth's horizon, and gives an immediate indication of the smallest orientation change.

    Attitude indicators have mechanisms that keep the instrument level with respect to the direction of gravity. It may take a few minutes for the erecting mechanism to bring the gyros to a vertical upright position after the aircraft engine is first powered up.

    The gyro is mounted in a double gimbal, which allows the aircraft to pitch and roll as the gyro stays vertically upright. A self-erecting mechanism, actuated by gravity, counteracts any precession due to bearing friction.
