The figure below, shows examples of off-scale areas, indicated by the grey shading.
Note, the grey shading is for illustrative purposes only and will not appear on the
published chart or display. These off-scale areas appear on the chart to convey
supplemental information. However, the depicted geographical position of this
information, as it relates to the chart planview, is not the actual geographic position.
Therefore, when the aircraft symbol appears within one of these areas, the aircraft
position indicated is relative to the chart planview, not to the off-scale area.
