It's doesn't seem like there is very much AI aircraft in FSX, even when the AI's are turned all the way up.What do you folks think?Also how many world flight plan schedules are in FSX?For example I think Ultimate Traffic has around 420,000.

I think there are roughly 34253 flights in the FSX AI traffic database.

FS was never designed to handle real world levels of AI traffic at major airports. There are still only five incoming waypoints to separate aircraft for each runway. Higher traffic levels results in two or more aircraft being assigned to each waypoint.The default FSX AI traffic is much higher than FS2004, but much lower than the real world at most airports.I've got a 115MB stats folder if you want it of how the FSX TrafficDatabaseBuilder program creates AI traffic with the default settings.It involves adding aircraft data to 35,243 cells around the world, and notes like this:"warning: Airport PAOR not usable by any auto-routed aircraftwarning: Airport RJTR not usable by any auto-routed aircraft"In the case of Kastner (great golf course at Camp Zama) the ruway is too short for any default aircraft (2,500 ft min for auto-routing). Northway has a long enough runway - but it might be a range issue - don't know.Anyone notice that the default AI now has local regional registrations in FSX?

>Anyone notice that the default AI now has local regional>registrations in FSX?Wow, hadn't noticed this! That's a pretty neat little detail :) Not all aircraft have regional registrations, though, suggesting that some AI aircraft "come from afar". I was sitting at EFHK and looking at the AI aircraft list and there were a couple of aircraft from Sweden and UK as well as some I didn't recognize.

The "auto-route" aircraft tend to fly close to their max range - which in Europe can cover several countries.If you have the Deluxe version and have installed the SDK's - you can see the default settings in the fs10.AircraftTypes.csv.But, I'm willing to bet the registration is approximately correct at one of the two airports in any default aircraft flight plan.But even so, it still beats N# US type registrations world-wide.The greatest number/ percentage of invalid registrations continues to occur in the United States.The number ZERO cannot be the first number in an aircraft registration by the US FAA rules - but every automated program always puts 10% of the reg #'s with zero as the first digit. :-(
