A Correct answer
Explanation

The attitude indicator operates on the principle of gyroscopic rigidity. The gyroscope in the AI maintains a fixed orientation in space due to rigidity, while the aircraft rotates around it. The gimbal system allows the gyroscope to remain stable while the aircraft case moves, providing a reliable artificial horizon reference for both pitch and bank information.
