I am using Ultimate Traffic to provide AI traffic for my virtual world on flight sim, but I have just downloaded an AI Britten Norman Islander in the Mountain Air livery and it's flight plans for New Zealand.
What I want to know now is how do I make the planes fly around as AI traffic alongside my UT AI planes...?
Also, does it matter that the flight planes say "For Summer 2004-2005"
Does this mean I will have to set my simulator to "Summer 2004-2005" or I will not see them?
The "For Summer 2004-2005" means that the plans were built from real world information gathered on actual routes for that airline. It does not mean you have to change FS9 settings to see them.
A good starting point for flightplans is here
A very useful site.
