Question for Tim Capps:

How did you prepare a transatlantic flight plan?  

When I tried with other CS aircraft, JFK to Lisbon for example, FS wanted to route me way back west and then north and finally east, something like a 20 hour flight plan.  The only way I could get other aircraft to follow a transatlantic plan was to enter it as a GPS  direct route with only a beginning and end point, and then add by drag and drop in the map about 2 additional waypoints at each end of the route.  Even then sometimes the 757 and 767 went off track.  I haven't tried this with the 707 DNS as yet.

Is there a better way?

I haven't made the DNS modification Capatin Sim recommended in the KB;  does that matter?
