*Note: this serviceable BF Goodrich Standby Attitude Gyro comes with a yellow-tag.
The Attitude Indicator shows rotation about both the longitudinal axis to indicate the degree of bank, and about the lateral axis to indicate pitch (nose up, level or nose down). It utilizes the rigidity characteristic of the gyro. It is gimballed to permit rotation about the lateral axis indicating pitch attitude, and about the longitudinal axis to indicate roll attitude. Once powered up, the indicator is maintained in a fixed position no matter what the aircraft attitude may be.
