Description
AGR-74V-10 Series 2 artificial horizon
AGR-74V-10 Series 2 is a gyroscopic artificial horizon used in aircraft flight and navigation instrument systems. The instrument provides the crew with visual attitude information relative to the true horizon. It displays roll and pitch angles and supports aircraft attitude monitoring during different flight conditions. The unit is installed on the instrument panel and is used as part of the onboard flight reference set. It is an indicating gyroscopic instrument, not an autopilot actuator or flight control drive.

Roll and pitch indication through AGR-74V-10 Series 2
The instrument shows aircraft bank and pitch position using its gyroscopic assembly and display mechanism. Roll indication covers full rotation, while pitch indication is limited by the approved operating range of the instrument. The display gives the pilot a direct visual reference for aircraft attitude, especially when outside visual references are limited or unavailable. Proper operation depends on correct power supply, stable gyroscope run-up, installation angle and serviceable indication mechanism.
AGR-74V-10 Series 2 output signals
In addition to visual attitude indication, the instrument generates AC electrical output signals proportional to roll angle. These signals can be transmitted to external onboard circuits that require roll reference data. This makes the unit part of both the cockpit indication system and the wider avionics signal chain. If external attitude-related functions show incorrect data, the check should include the artificial horizon, output circuits, connectors, wiring and associated receiving equipment.
AGR-74V-10 Series 2 on Ka-32 helicopters
AGR-74V-10 Series 2 is used on helicopters and fixed-wing aircraft equipped with compatible flight instrument systems. A specific application is the Ka-32 helicopter, where the unit forms part of the standard attitude reference and navigation instrument equipment. Exact applicability depends on aircraft modification, installed instrument panel and avionics configuration. Similar artificial horizons may differ by power supply, output signal configuration, mounting version or failure warning arrangement.
Identification and ordering of AGR-74V-10 Series 2
Before ordering, the full designation and series should be checked against the aircraft parts catalog, avionics documentation or product passport. The “Series 2” marking is important and should not be omitted when confirming interchangeability. It is also useful to verify the power supply, illumination voltage, output signal requirements and aircraft installation. The product is also known under alternative designation AGR-74V-10 Series 2.
