FlightAware and FlightRadar24 are operating as businesses that make a
lot of money (FlightAware in particular) providing tracking services
to government, corporate, private, and airline clients. In order to
provide the most data possible to their customers, they need the
tracking data feed from the FAA. Part of the deal with using FAA data
involves agreeing to filter out the tracking data for aircraft that
the FAA has agreed to block - which is not location-specific. While
this may irritate us as photographers / spotters / hobbyist, we're not
their cash cow and they're not going to dump the FAA feed to make us
happy. :)
Planefinder is geared to photographers / spotters / hobbyist and
doesn't use FAA data. This allows them to display whatever the like -
but they're only going to be able to show what they can gather on
their own.
ADS-B feeders at FlightAware receive an Enterprise account for free
(normally US $89/month). With this account, I can track and see some
flights that aren't available for public view on the free site or to
those that are logged-in with lower level paid accounts (positioning
flights, some military flights, etc). While this still doesn't get me
access to FAA-blocked aircraft, I can usually see tracking data for
them if they fly through an area where I'm providing ADS-B / MLAT
coverage. At that point, though, it's pointless for me to use
FlightAware or FR24 to see those birds as I can simply open Virtual
Radar Server on my computer and see their full data block on that map
as they're transmitting data to an antenna on the roof of my house.
This can come in handy if a blocked aircraft departs from a local
airport as I can see their reg. number while they're within my
coverage area...and then continue to track them as an unidentified
aircraft on FR24 / FA after they leave my area.
Several country music artists keep their private jets at BNA (Taylor
Swift, Kenny Chesney, Brad Paisley, Alan Jackson, and so on) as well
as several corporations that have their tracking data blocked with the
FAA. I see them depart BNA all the time on my own ADS-B map (with
reg. number) and can easily match that up to the generic Falcon 900,
Gulfstream 550, Learjet, etc. that appears on the public tracking
sites with no registration details (if i really cared enough to track
bizjets).
