In terms of certification, what aircraft is certified as what? I know planes are theoretically capable of certain weapons layout but certification is another matter. For example, the J-7G can theoretically carry BVR missiles, but it doesn't. Is the J-8B certified to carry the PL-11? Does the J-8E carry the PL-8? Is the J-8F the only variant of the J-8II that caries the PL-12 or can the J-8H also capable of using and is certified for the PL-12?
