ASN is integrated into their application. It's part of their program. :-/

I don't think I would say that ASN is "integrated" into the other 777:

ASN is the first weather addon to output an external 3D precipitation model, which we’ve used to accurately model the operation of the radar. The weather radar does not currently function with default FSX weather or with any other weather addon.

Without ASN, its WXR is INOP! ;D
