An observation from the virtual world:
In the process of VV&A of civil and military simulators it remains a challenge to explain why in zero wind compass heading, VOR radial, GPS, and ground track are not all identical. The reasons are multiple. I am repeatedly surprised by the number of Chief Pilots, O4s and CW4s that "Know" VORs are aligned to current magnetic north. I have yet to run across a pilot out side of engineering test that understands vertical CG has any effect, "if the ball is centered in zero wind, heading and track are identical."
These pilots all seem to discount the variation they see in the real world to “unreported wind variations” This explanation has always satisfied them until the day the get to be God, and have absolute control of the wind. Now the error must be in a “phantom wind” (or the aeronautical engineers lack of understand of physics) because they “Know” given the opportunity to zero that wind all references (compass, VOR, GPS, and ground track) will align perfectly.
Previously you covered the physics that accounts for the differences in these navigation references. Keep them and fortify them with additional real world navigation examples.
BTW - FSXXI is due to add more simulators soon; Ft Rucker’s Warrior Hall will be full plus some. Know that the young men and women that walk through those doors, though they may never know it, in some way benefit from your life’s work.
