FSX Alaska Navaid Update 2011. The default Flight Simulator database of VOR/NDB's is fast becoming out of date, making VOR navigation using current IFR en-route charts impractical to impossible. When flying along charted airways, this discrepancy can cause you to become far off course. This update solves that problem by re-calibrating all navigation aids in Alaska (AK) based on information submitted to the FAA January 13, 2011. This allows you to accurately navigate using any navaid in Alaska while using current IFR en-route charts. This update includes magnetic variation data, and navaid position. All data was compiled from the ground up. By Wilson Malone-AKFS Design.
