Ural Civil Aviation Plant (UZGA) will equip its next-generation regional aircraft with Russian-made avionics and communications systems supplied by NPP Prima, a Nizhny Novgorod–based radio electronics developer. The decision covers the LMS-901 Baikal, TVRS-44 Ladoga and LMS-192 Osvey programs.

UZGA tailored the avionics suite for each platform to match mission profile, aircraft performance parameters and life-cycle cost targets.

LMS-901 Baikal and LMS-192 Osvey
Both aircraft will receive production-standard Prima-MV VHF transceivers. The radios provide stable voice communications in the civil aviation VHF band and meet KT-160G/14G qualification standards, Russia’s equivalent to RTCA DO-160 environmental and EMI requirements.

The Osvey will also incorporate a domestically developed audio integrating and switching system comparable in capability to Western solutions in this aircraft category.

For operations in remote regions without VHF coverage, UZGA will offer the Prima-KV HF transceiver. It will be standard on the Osvey and optional on the Baikal. This architecture provides communications redundancy and extends operational reach in sparsely served airspace.

TVRS-44 Ladoga
The 44-seat regional turboprop will feature a more comprehensive communications suite. It includes three Prima-DB digital VHF radios, two Prima-KV HF radios, a CIMS-A–based intercom system and a CIMS-21 communications control unit.

The digital VHF radios support VDL Mode 2 and integrate with ACARS. This configuration enhances controller–pilot data link communications and improves operational efficiency in high-density airspace.

By standardizing on domestically produced systems, UZGA establishes a unified avionics baseline across its new aircraft family. The approach supports fleet commonality, improves maintainability and optimizes communications management. System architecture reflects route structure, mission requirements and aircraft-level weight and power constraints.
