RV-5M version V is an onboard radar radio altimeter designed for accurate measurement of true altitude above ground or water during low-altitude flight.
The system was widely used on helicopters and aircraft prior to the introduction of the A-037 family and was standard equipment on Mi-8, Mi-14, Mi-24 and several fixed-wing platforms.

The RB-5M provides continuous height measurement and supplies the crew with:
• real-time altitude information via indicator;
• visual and audio Danger Height warning;
• Failure/INOP signaling;
• pulse outputs for integration with other avionics;
• automatic health monitoring with a built-in control circuit.

The radio altimeter operates in the 4200–4400 MHz band and supports measurement ranges up to 1000 meters depending on configuration.
The system warms up automatically and continuously tracks altitude based on frequency-modulated radar reflection.

Supplied set (per passport), included in baseline system delivery:
— Transceiver RV-5M (PP-5M)
— Altitude Indicator A-034-4-24
— Two antennas AR5-1
— Shock-mount frame RA-5
— Main cable GU4.850.668-29
— Power/connection cable GU4.850-759
— Documentation, passport and operational manual

This configuration forms a complete ready-to-install radio altimeter set for aircraft integration.
