Dave - I would very much like to obtain a copy of your Utility as the ANRB update process is very cumbersome and slow. With AirNav using a photographic site to update a DB, (what logic!), my ANRB DB is constantly being corrupted with erroneous data. Yesterday I got an Air Canada DC-8 come up, a couple of weeks ago, it was an AC L-1011 - both long, long gone from the fleet. Those standout easliy but there are many biz and others which are less obvious; at an airport I can see from my Aerodata Analyser, (and confirm with my eyes), that the type that ANRB shows is in a fact a completely different type of aircraft, quite common with bizjets, but how much else is slipping through.
