This is a set of miscellaneous classes useful for dealing with ACARS messages. Probably the most significant thing here is the info.koosah.acarsutils.wxdecoder package; it can actually interpret and decode weather observations coded by 10 (at current count) different airlines. These observations use proprietary, undocumented formats; the airlines consider them trade secret information. (The supported airlines are merely those that fly in and out of SeaTac regularly and thus which I have acquired enough samples from to reverse engineer.) I have never worked for, or written code for, any airline or aircraft manufacturer. Therefore all reverse-engineering I have done above is "clean." The info.koosah.acarsutils.AcarsMessage class might also be of some interest, as it provides more message breakdown and explanatory information than most such open-source ACARS code out there.
