I think the problem might be that AS2012 is not designed so that users can add their own regional airports to a list of airports that should be searched for data.AS2012 should have a process on the local machine of each user, that checks for METAR data for these custom user lists, and then combines it with the master download of weather that comes from HIFI. That would be great because it adds flexibility to the system. Users could trade off the downside of inserting more data into FSX without affecting other users who are not interested in that data.I'm only guessing, but AS2012 probably has one master list that applies to all AS2012 users around the world. The problem with that is that if too many regional airports are added to the AS2012 master list, the download and insertion times into FSX are deteriorated for everyone simply because of these regional airports.I'm only guessing! Thinking out loud.Cheers
