What are the basic components of an attitude indicator?

The essential components of an attitude indicator are a gyroscope, a gimbaled structure, and a display. The gyroscope is crucial for providing the necessary stabilization needed to determine the aircraft's orientation relative to the horizon. The gimbaled structure allows the gyroscope to maintain its plane of rotation despite the movement of the aircraft, ensuring that the indicated attitude relative to the horizon remains accurate even in dynamic flight conditions. Finally, the display component presents the information in a visual format that pilots can easily read, typically showing whether the aircraft is climbing, descending, or in level flight relative to the horizon line. These components work together to give pilots critical information about their aircraft's attitude, which is vital for maintaining control, especially during instrument flight conditions where visibility may be limited.
