In the real plane there on the ND (navigation display) a weather radar it will be more realistic if there is one on the AirTrack.

Yeap, this would be nice. Perhaps for a future version.

The problem would be to access the weather in the flight sim. I might look of how it's done in X-Plane but not sure about FSX ...

Unless we only use real weather from the Internet like the one AirTrack uses for the METARs which is also possible.

thanks for the suggestion,

There're different types of weather modeling: in FSX it takes METARs from some points (if using Active Sky, it creates virtual ones) and generate weather and clouds using them; in X-Plane... in fact, I don't know how for sure, but I guess it takes a huge square of weather around the plane using actual satellite weather (forgot where from) with clouds, temperature, pressure and more things WITH DIFFERENCE IN ALTITUDE (FSX don't) and creates weather using this. So, maybe there will be two different works for two different plugins for the one feature. Phew!
And yeah, what about VATSIM weather? Sometimes it becomes different from real one.
