Gyro-Horizon G6A/3182 643720-R

Used on RAAF aircraft in WWII.

The gyro-horizon, a device which created for pilots an artificial horizon so that the orientation of an aircraft with respect to the earth's horizon could be indicated accurately without the earth's horizon being visible. Like the directional gyro it consisted of a spinning wheel (15,000 revolutions a minute) supported by gimbals, but it was also fitted with a pendulum and vanes which automatically corrected any drift error caused by friction in the bearings.
