I live in Adelaide, South Australia an I have spent a modest amount of time listening to ATC-Live while following the traffic on
FlightRadar24 or
PlaneFinder but many of the aircraft don't show up.
I know AirServices have a "
Web Track" service which seems to show a lot more aircraft but when in "Show current flights" mode the movements don't seem to correlate to ACTLive, FlightRadat24, PlaneFinder or even my own observations. Is anyone able to explain the disparity and possibly suggest a better method of observing?
Here are a couple of screen grabs I took within a few seconds of each other showing the difference between "Web Track" and FlightRadar24:
Web Track:
FlightRadat24:
As you can see there are numerous discrepancies between the images. The only thing that seems to correlate is the SYD-ADL flight in the NE but even then one lists it as a A320 at 4500' while the other lists it as a B737 at 6700'. In my observation FlightRadar24, PlaneFinder and LiveATC all seem to correlate with my own observations so it appears it's AirServies "Web Track" that's out. I know "Web Track" use to have a 1/2 hour delay but I see that is has a "Show current flights" mode now a but is this mode still delayed?
Just now I brought up these three sites as a large helicopter just flew low over my house and I wanted to see what it was. I suspect it was the Westpac 1 rescue helicopter but wanted to see it on radar to confirm. It has not shown up on any of the radar sites and I have been monitoring "Web Track" for over half an hour now and it still hasn't shown.
Is anyone able to explain what is going on?
Thanks.
