There are loads of places worse than Vnukovo. Luanda and Lagos spring to mind but these places have not just invested billions for GA operators and then it all falls flat cos of ATC, Fuel, etc.
V3 now has the infrastructure to be OK. It's 90% there but the remaining 10% is all so important.
ATC is the biggest problem with simply no idea how to space incoming a/c. How about heading control or speed control before TOD rather than 100 miles of vectors from the downwind leg????
