National Flight Centre in Dublin has an interesting functional decor item next to the front desk: two big flat-screen televisions showing the location of the flight school’s fleet (why two? a view of the traffic pattern and then a view of the region). ADS-B is not mandated in Ireland currently so they are doing this with portable GPS trackers that are in a key/notebook bag that students take out to the plane when renting. For a U.S. school in a transponder-required area, however, I think the same thing could be done with software pulling ADS-B data from public sources.
When customers and potential customers come in they can see all of the fun that is happening. For our school it would be planes out on Cape Cod, up in Maine, etc. (Would need to program the software to show the last received position so that the plane does not disappear from the Martha’s Vineyard airport once shut down.)
Readers: What’s the easiest way to build this using ADS-B data? What source?
