Paul Henty Posted July 9, 2009 Report Share Posted July 9, 2009 Hi Pete, Your trafficlook program displays the magnetic heading of the AI planes. As FSUIPC only gives the True heading, are you assuming that the AI planes have the same magnetic variation as the player? Or is there something more cunning going on there? thanks, Paul Link to comment Share on other sites More sharing options...

It uses the MagVar at the user aircraft. Since the max range for AI is around 60-80nm, or about 1 degree of arc, it will not be far out. I suppose I could read the MadDec BGL (which is merely a complete table of MagVars) and work out the correct value, but it isn't worth it -- the difference would be small, even in areas of maximum change.
