Attitude Indicator

, GH025/GH025C/GH025Y/GH025YC

The GH025/GH025C/GH025Y/GH025YC attitude indicator is constructed in line with TSO-C4c standards, suitable for use on small civilian airplanes. There are essentially two purposes the attitude indicator can serve, measuring the fore and aft tilt as well as side-to-side tilt of an airplane. With startup time no more than 3 minutes, the gyro horizon delivers excellent performance.

Measurable side-to-side tilt range: 360°
Measurable fore and aft tilt range: ±80°, with adjustable reference mark no less than ±5°
