The experimental Russian SJ-100 underwent flight tests in Belarus, where specialists from Yakovlev checked the autopilot, automatic landing approach, and the aircraft's operation in approximately 100 modes. Tests were conducted at Minsk and Orsha airports in various speeds and weather conditions – from ordinary daytime conditions to night flights in fog.
During the program, not only the standard operation of systems was checked. Test pilots practiced the minimum landing approach speed, piloting errors, go-around, and landing with simulated engine failure. The obtained results should be included in the certification materials for the import-substituted SJ-100.
The choice of Minsk is due, among other things, to its proximity to Zhukovsky airfield and the ability to use satellite navigation to assess the accuracy of approaches.
Firstly, Superjets, as we call them, of the basic version, fly here and are already undergoing normal operation. Secondly, the city of Minsk is not so far from Zhukovsky airfield – it's only a 1 hour 15 minute flight. Thirdly, there is a very good situation here in terms of satellite navigation. We can assess the accuracy of approaches using satellites. And we just like it here.
Tests of the import-substituted SJ-100 continue at other sites, particularly in Novosibirsk. The next stage will be checks in high and low temperature conditions: flights in hot weather are planned in Uzbekistan.
