A-037 Version 10

The A-037 Version 10 is a complete radio altimeter set designed to measure true flight altitude of a helicopter above any type of terrain — land, water, or rugged surface.

The system consists of:
• A-037-1V transceiver — signal generation, transmission and reception;
• A-034-4-22 height indicator — analog pointer display and warning output;
• Two A-037-2 antennas — transmitting and receiving;
• GU4.137.080-01 mounting harness and frame;
• GU4.850.668-03 interconnecting cable.

The A-037 system provides the aircraft crew and onboard avionics with:
• continuous indication of current flight altitude on the analog scale;
• aural and visual low-height warning when descending below the preset value on the indicator;
• fault indication — a red flag on the indicator scale when a malfunction is detected, radar contact with terrain is lost, or the aircraft exceeds the display range (approximately 300 m).

The system operates on continuous-wave radar with frequency modulation.
Altitude is calculated from the delay of the reflected signal, providing real-time height data in low- and mid-altitude ranges.

Alternate / Alternative names:
A-037 Variant 10, A037-V10, A-037-10, A-037 kit with A-037-1V and A-034-4-22

Use of the system is permitted only under applicable aircraft documentation.
Reliability, electrical requirements, and accuracy are derived from the manufacturer’s passport and confirmed test data.
