Since Russia, and in particular the Asian part of it, is huge, I was wondering if there are special procedures for commercial pilots to follow over Russia (in particular and specifically Siberia and other sparsely populated parts)? (Except that they use the metric system.)
Does Russia provide radar coverage and flight following services over its entire territory? As an example, do the use procedures like the North Atlantic Tracks, or do pilots implement their "own ATC" by stating position reports regularly, just like over some parts of Africa?
Or is flying over Russia comparable to flying over any other European / U.S. / ... country with continued ATC service?
