I created some 52-week plans for my own use in FS9, they are formatted for FS9 (week day numbers). Some categories of aircraft (eg club and school aircraft) will tend to be busier at weekends, while for business aircraft it will be the other way around. All weeks have aircraft that fly into the early evening after dark, and all but the Piper Seminoles and C210 will be flying VFR. There are a very small number of TNG details.
Some aircraft (eg Druine Turbulent, Tiger Moth etc) that absolutely look mad flying at night will get flightplans that vary with the seasons (shorter flying days in winter, longer in summer), but there's nothing here that needs that sort of detail, so the flying day is the same year-round.
Bases are derived from these sources in order of acceptability
1/ Tracking sites
2/ G-INFO where possible
3/ Images where possible
There are some bases with accepted FS9 ICAO substitute codes for FS9, for example X6IN (Insch) and X2EG (Eggesford). Only aircraft based at these places will tend to visit them.
I think the repaints for all of these are here on OCH.
You can use just one of the weeks if you don't want the routes and timings from their bases to constantly change.
