United Aircraft has flown prototypes of the Yakovlev SJ-100, Irkut MC-21-310 and Ilyushin Il-114-300 to Arkhangelsk's Talagi airport to carry out natural-icing trials. Specialists will evaluate aircraft systems and performance in real-world icing conditions to support certification and operational readiness.

Briefing
Natural-icing trials are a critical step in validating aircraft environmental performance and safety ahead of certification and entry-into-service timelines; successful results directly affect program schedules and operator deployment.
The tests matter for near-term fleet plans: Il-114-300 serial deliveries are slated for 2026 and operator induction depends on proven winter performance (Il-114-300 serial deliveries in 2026); MC-21-310 development is tied to domestic component substitution and performance restoration (MC-21 import-substitution and range targets).
Outcomes will feed commercial and industrial strategies, including licensed-production and export discussions that reference the SJ-100 and Il-114 platforms (licensed manufacture talks with HAL and UAC) and marketability for regional routes.
