Looking good, but my main concern is with your dirt runway, a modern jet aircraft would never take off from one as there is far too much risk of engine damage from the engine sucking in some dirt, stones or w/e into the engine on take off as well as the very large risk of the wheels digging down into the dirt and the entire aircraft flipping over or having its landing gear damaged at the very least,
which was a massive problem for the Pucara in the Falklands war, even thou it was a repetitively light, turboprop aircraft.
In the Falklands war the Brits did make a Forward Airbase for their Harriers at San Carlos using some kind of metal matting, something similar to
Marsden Matting which they used back in WW2, Vietnam and still a bit today, entire airbases where crated in the Pacific using them:

You could perhaps look at doing something similar? Although don't know if this kind of matting is stable or safe enough for modern day jets with a long take off. Also it is more of an option for the Harrier not only because it has a much slower take-off speed than most aircraft but also a much shorter take-off in general which meant that it didn't need to be very long. Fast Jets, although require a much shorter runway ingame than in r/l, wouldn't really have this option I don't believe but still a far better option than a dirt runway.
I would also suggest you seriously consider and look into making a proper airbase, especially if you go down the metal matting route as they would be best done in this new system:

I know that finding someone to model them isn't easy but doesn't take much to draw up the dimensions and layout of what you need then ask someone on these forums if they would give a shot at making it
As for the rest of the map it looks pretty good, some nice colour work I see with the terrain, although your water colour needs quite a bit of tweaking.
EDIT: also from this pic:
http://i.imgur.com/jY53lTi.png looks like either your low detail texture is very, very repeated, or your detail texture is drawing really far away, you can see the repetition from only 100m away... This doesn't only look bad but is really bad for performance. Should lower your low detail tiling a lot and/or reduce your detail texture draw range for the same reasons. And also you should remove the undergrowth off of your roads and fix up the alpha but most likley your GFX card that's the problem there.
