I've always used the on-board FSX flight planner to plan my real-world flights that I obtain from http://flightaware.com/, and overall, it does an adequate job.

 

But in some parts of the US/Canada,  airspace fixes (intersections) are missing,

 

Does anyone know a good source which can add in the missing intersections in one easy step to the FSX flight planner (not one at at time).

 

Thanks.

Good afternoon Bob

 

This will update the FSX database and most, if not all, of those 'missing' waypoints will then be available for flight planning.

Terrific.  Thanks, Brian.
