Aircraft within a certain distance of an airport

IS it possible to set the system up so it tracks any aircraft within, say, 20 miles horizontal or an airport? For the whole day? or whatever…this may not be possible, due to deviations in flight plans sometimes, but i was jsut curoius.

It is possible, but it would take a good bit of development work. I don’t see it happening in the near future for free.

ok, well, i can wait :smiley: would be sweet though
