The heading indicator (also known as the directional gyro, or DG; sometimes also called the gyrocompass, though usually not in aviation applications) displays the aircraft’s heading with respect to geographical north. Principle of operation is a spinning gyroscope, and is therefore subject to drift errors (called precession) which must be periodically corrected by calibrating the instrument to the magnetic compass.
Features:
operating voltage: 14 ± 10% V DC
ambient temperature: -40 – +50 °C
ambient relative humidity: no more than 95%
vibration strength: 1.5g
working range: indicating heading angle within the range of 360°
accuracy: the drift error is not more than 4°/10 min
operating current is not more than 0.72A
rated Rotating speed is 22000 turns per min: it warns when power-off the rotating speed is below 70% of the rate rotating speed
the insulating resistance between the power and case is not less than 20M?

The attitude indicator (also known as an artificial horizon) shows the aircraft’s attitude relative to the horizon. From this the pilot can tell whether the wings are level and if the aircraft nose is pointing above or below the horizon. This is a primary instrument for instrument flight and is also useful in conditions of poor visibility.
Features:
ambient temperature: -40 – +50°C
ambient relative humidity: no more than 95%
vibration strength: 1.5g
working range: banking 360°, pitching ± 70°
the gyro can return to zero point from any point and lock-in.
accuracy: the indicating error is not more than ± 1°
operating current is not more than 0.8A.
reference mark should be adjusted in the range of not less than ±5°
the insulating resistance between the case is not less than 20 MOhm

MC022 magnetic compass can provide directional reference of geomagnetic meridian and indicate magnetic heading of an aircraft. It has advantages of simple structure, good independence and reliable operation. It is an indispensable compass in aviation. It is mainly used in small aircraft, indicating magnetic heading.
Features:
360-degree azimuth can be seen clearly by adopting vertical azimuth dial
Fast drying, fast penetrating, strong flow action cleans and degreases delicate precision parts. Removes oil, grease, dirt, flux and other contaminants. Safe for use on metals and plastic, inverta valve for 360° spraying action.
