Google Earth flight simulator visualization showing how the Angle of Attack (AoA) changes during the final approach of an F-16 flight. In the first part of the approach we have a negative AoA (dotted yellow line is under the uninterrupted yellow line). The distance between the 2 yellow lines grows, showing that the AoA increases as we approach the runway. The red mark appears when the 2 yellow lines actually meet together and the AoA is zero.
