Practice, practice and practice.
Many of the Russia airports without ILS might have an NDB. Knowing where on the field that is located will help you use it for guidance.
From my real world small GA flying experience, I almost always overfly an airport before I land the first time unless the weather is super clear with unlimited visibility. With any kind of haze, I want to get a good look at the field before I come into the pattern to land.
I do the same thing in FS, in jets or props. Fly over the field on a missed approach to make sure I'm established where I want to be, and can then fly a proper pattern.
But the main thing in FS is to practice, practice, practice. It takes hundreds of landings to be comfortable flying into strange airports with less than perfect visibility.
