New issue 518 by h....@hy...: LNAV course on Map using Great Circle  
Course
http://code.google.com/p/flightgear-bugs/issues/detail?id=518

When the distance between way point is larger such as between RJCN and UHPP  
over 700NM, LNAV course on Map application is drawn as direct line of  
Mercator map. This causes discrepancy of course heading and ship heading  
and deviate from the course. Eventually ship arrives next way point but we  
get the deviation until that time.
Could we have Great Circle Course between waypoint?
Best method is change the Map to sphere.
Then we can fly even over the pole on the map.
