"just in case someone believes this to be a new FSX feature."As you climb in altitude the effect is a whole lot different in FSX than it is in FS9 (just in case someone believes this is not a new feature).I've seen plenty of videos that confirm FSX gives you the curvature of the earth as you climb in altitude.Check the link out below to see what's not possible in FS9.http://www.youtube.com/watch?v=a-xYZSGBWrc...related&search=

Hi Reggie!The "crown" on top of the earth's "head" (see my earlier posting) is a very satisfactory SMALL spot then. Let's hope that, when FSX ages, the bald spot doesn't expand like it tends to do on the head of us blokes (grin)!Seems that the developers have strived for, and indeed reached, the maximum obtainable: an almost pinpoint-small spot that's actually unflyable, while immediately next to that spot life (and your aircraft) retakes its normal course. Good oh!Be well!Jaap Verduijn.

I didn't mean the curvature, I meant the globe overview with the top down view. ;)That video is impressive indeed. Almost looks like the real thing from up there.

The is a fundamental mathematical problem with overflying the poles using the world coordinate system (latitude and longitude).Assuming you are flying due noth to the north pole then, when you fly over it your heading changes instantaneously to due south at an infinite rate. It goes from 0 deg to 180 deg in an infinitely small period of time.The undelying reason for this is the mathematical function tan. This become infinite at 90 deg (north pole) and at 180 deg (south pole).There are ways to get round this but presumably Microsoft, not unreasonably, didn't think they were worth implementing.

I think this representation will be close enough for any simmer and a significantly vast improvement over the past.

I cant wait for the PMDG 747-400F to be FSX compatable so I can watch the magnetic heading swtich go to TRUE!
