Hi Andrei, and welcome.
If you haven't done so already, you could ask AOPA Ukraine (aopa.ua or aopa.org.ua).
You might also enquire on euroga.org, but most of those guys are upper airspace cruisers, whereas it sounds as if you're looking for advice from "bottom-feeders" like us...
Good luck, and when you have found the info you're looking for, please come back and post it here, with trip reports. Reports including photos of real sunshine would be a source of fascination to those of us in northern Britain...
