Garrett, X-Plane's data that you speak of is mainly airport updates...usually re-alignments of taxiways, sometimes better alignment of ILS fixes that were otherwise incorrect in previous data. In most cases, it's user submitted to Robin Peel and he packs it up and publishes it to everyone on the site you have linked to. To add to this, X-Plane data contains no SIDs or STARs information at all. Yes, what comes included with the aircraft is from 2006. Keep in mind that the only REAL difference here is STARs and SIDs change frequently, hence the reason there are always new cycles released. Waypoints, otheriwse known as VORs and NDB's, etc, are pretty much stagnant and always remain the same, thus such information is NOT outdated. The Navigraph data only affects the use of the FMS, and nothing more. As such, I'll echo your own words and put them out as a statement that your concern is in fact unfounded. Choosing to fly by radio frequencies and charts has nothing to do with the data we are speaking of in this topic. For someone who chooses to fly like you, nothing has changed.
