I agree with PFunk too, the ODS mod is just amazing and at the moment is at the top of SF development. But adding a working A-G radar can enhance the experience a lot, specially for planes like the Hornet or the Strike Eagle, does not have to be more complicated than the current A-A radar, but that and CCRP will improve the game a lot and will let the player play until nowadays planes.
Can you imagine flying a argie Super Etendard in bad weather over South Atlantic and searchig for a radar eco for your Exocet without knowing If you will hit a british carrier or not...
Or searching for SCUDS in the open desert at night using the radar to hit'em hard with a GBU...
The same goes for NVG, are those that really hard to add? Not need to be the lighted circle of real life NVG but a simple filter that let you see outside and that can be activated and deactivated trough player in game input.
I agree about A-A refuelling as being useless cause maps are not to scale, but not about some guys saying is too hard and does not match SF. Anyone remember the Falcon 4 refuelling options? there is one that let you do all the approach and once you're close to the boom it takes control of the plane until is fully refuelled. Air to Air refuelling are part of every air campaign in the last 50 years, not having them is a lost to the sim.
So many options...
