As Kommersant found out, the main operators of the SSJ-100 complained about failures and incomplete information in the built-in navigation base of the aircraft. After the French Thales stopped updating software for Russia in 2022, Irkut approved the use of the database of the St. Petersburg Avia Briefing. Rossiya, the largest SSJ operator, asked to replace the system with an alternative development of the ATM Civil Code. But Irkut reminded that this development has not yet been certified. The SSJ-100 pilots interviewed by Kommersant confirmed periodic errors in the operation of internal navigation, but most consider them non-critical.
