ID-6 Series 1

Magnetic sensing function of the ID-6

The ID-6 detects the magnetic field components along two mutually perpendicular aircraft axes, normally aligned with the longitudinal and transverse axes of the aircraft. This allows the system to determine magnetic heading information from the Earth’s magnetic field. Since raw magnetic data can be affected by airframe magnetization, onboard equipment and installation conditions, the ID-6 is normally used together with correction mechanisms and gyro units rather than as an independent cockpit instrument.

ID-6 with GA-8 and KM-2 units

In typical aircraft heading systems, the ID-6 operates together with units such as the GA-8 gyro unit and KM-2 correction mechanism. The ID-6 provides the magnetic reference, the KM-2 introduces correction and compensates residual deviation, while the GA-8 stabilizes and memorizes the heading in gyro-semi-compass mode. This combination helps reduce magnetic fluctuations and provides a more stable heading signal than a standalone magnetic sensor could deliver.

Role of ID-6 in Greben-1 and related systems

The ID-6 is used in aircraft heading systems such as Greben-1 and compatible Soviet / Russian heading equipment. It may also be found in systems related to magnetic or gyro-magnetic heading formation, depending on aircraft configuration. The sensor is part of the heading reference chain, not a separate display unit. Its output is intended for further processing, correction and synchronization inside the heading system before heading data is shown to the crew or sent to connected systems.

Installation of the ID-6 heading sensor

The ID-6 heading sensor is usually installed on the aircraft structure in a location selected to reduce magnetic interference. Depending on the aircraft type, this may be an area of the wing, tail, fin or another approved installation point away from strong magnetic fields and electrical disturbance sources. The sensor body is typically made as a sealed cylindrical or hemispherical housing on a flanged base. Correct orientation along the aircraft axes is essential for proper heading measurement.

Accuracy and environmental stability of ID-6

The ID-6 is designed for operation in aircraft conditions, including vibration, moisture exposure and wide temperature variation. According to the supplied technical description, the remote transmission error is not more than ±0.5°, while the temperature-related error is not more than 0.1° per 10 °C. These values are important because the sensor is part of a precision heading system. After installation or replacement, the heading system normally requires checking, alignment and deviation compensation.

Important note on ID-6 designation

The designation ID-6 may refer to two different devices. In aircraft heading systems, ID-6 Series 1 usually means the induction heading sensor. However, there is also an ID-6 inductive pressure sensor, drawing 9Zh2.329.000, used for remote measurement of excess pressure in liquid and gaseous media. These are completely different products with different functions, construction, installation and technical parameters. When ordering or replacing ID-6, the application and drawing number must be clarified.

Supply and documentation for ID-6 Series 1

For procurement, the full designation ID-6 Series 1 should be stated together with the required application: heading sensor or pressure sensor. For the aircraft heading sensor, the heading system, aircraft type, condition and documentation should be specified. The product may be supplied from storage, serviceable, repaired or in another agreed condition. For installation, the passport and system documentation should confirm designation, series, acceptance, configuration and suitability for the target aircraft heading system.
