On your ADS-B user stats page (located at flightaware.com/adsb/stats/user/), each receiver (contingent on sufficient data) now shows a radial chart depicting that receiver’s coverage distribution.
This chart breaks your coverage into sixteen cardinal directions, and for each direction it shows five distance ranges (0-50 nm, 50-100 nm, 100-150 nm, 150-200 nm, 200+ nm). Each distance range is represented by a colored block. If you hover over a block, a tooltip will show you exactly how many positions we’ve received in that region of coverage.
A darker block means we’ve received more positions in that region, and a lighter block means we’ve received fewer. The colors also indicate this: a light blue block means we’ve received comparatively few positions in that region, whereas a dark red block means we’ve received comparatively many positions in that region. Green blocks fall somewhere in the middle.
