The main operators of the Sukhoi Superjet 100 (SSJ-100) aircraft have asked the Irkut aircraft manufacturer to allow them to install alternative navigation databases (NDB), Kommersant writes, citing the April minutes of the meeting in the Federal Air Transport Agency.
According to the publication, Rossiya Airlines, the largest SSJ operator (its fleet includes 78 superjets), asked the manufacturer to replace the databases of the St. Petersburg company Avia Briefing with an alternative development of the Aeronautical Information Center (CAI) from the State Corporation for Organization air traffic (ACT) after identifying problems with the use of an authorized base. However, Irkut denied the carrier, citing the fact that this development has not yet been certified, the newspaper notes.
Gazprom Avia and Red Wings also announced the incompleteness of the aeronautical information contained in the Avia-briefing databases and periodic navigation failures. Failures and errors in the built-in navigation base were confirmed to the publication by pilots from three SSJ-100 operating companies.
The developer of alternative navigation bases carried out work to bring their bases into the format of the aircraft navigation system, as well as a number of checks, including on a simulator, and contacted Irkut several times, but received no answer, a representative of the ATM Civil Code said at the meeting.
“The issue of using navigation databases is within the competence of the aircraft manufacturer, which, together with the aviation authorities, determines the conditions for the admission of suppliers of this data,” Rossiya told the publication.
