Check out the links in my signature below for more information on that.(working on new lists with all real-life equivalents but it's taking time...)__________________________________________________________EricUPDATED: List of all airlines, aircraft manufacturers and aircraft types recognised by ATC:http://www.geocities.com/eric_2203/orhttp://ftp.avsim.com/library/esearch.php?D...atID=fs2002misc

You may want to change "atc_heavy=1" to "atc_heavy=0". I believe heavy is for the big birds -- 747, 777, A340, etc.
