Why is my gyro precessing video

Precession occurs when the vacuum or electric motor of an AI operates outside the design limits, or when any excess frictional force disturbs the free rotation of the gyroscope at design speed. This causes a slow falling out or sluggish movement of the indicator. Precession will keep the instrument from giving a correct reading. Precession can be caused by bearing issues, wear and tear and other factors. Learn more: https://www.mcico.com/resources/flight-instruments/why-is-my-attitude-indicator-precessing
