Aircraft: Flight Profile By Down Range

Flight data sampled using a constant downrange distance between grid points. Note: the downrange for a hovering aircraft will not increment as the time increments, meaning that vertical lines can appear on graphs using this data provider.

Type: Fixed data. Intended to be used only with elements from this same data provider.
