Welcome to Rossiya, the portal dedicated to Russian and Soviet virtual aviation.
This portal has been created in order to respond to the growing demand from Flight Simulator's community. In fact, more and more flight simmers are seduced by Eastern aeronautics and want a structured approach to what they believe is unattainable. That's precisely why Siberia Virtual created Rossiya, which aims at being a reference as regards Flight Simulator add-ons dedicated to Eastern aeronautics.
There is a tutorial section too, where you can find explanations on how to download on avsim.ru, how to fly some add-ons, etc...
Please notice that Rossiya's content is updated very often, that's why you should visit it regularly if you want to be up to date.
