Not very often - but again here and there - I have the feeling that some radars feed
-> fake flight data
to FR24.
Here an example (screenshot from 23-DEC-2016 22:39 UTC):
FAKE.jpg
This one was not spotted by my equipment (a first indication - however: no proof, as my DVBT dongle - theoretically - may listen "beside" the frequency used by the AC).
BUT:
What makes me wondering:
1) AC's altitude is @ 30.000 feet, which is quite a "high" one. So I would think that - in most cases - an "F"-radar should be the "actual spotting radar", which is not the case here, although the area is brilliantly covered by "F"-radars spotting ACs flying even at much lower altitudes than this one. ACs with "high" altitudes in this area are spotted by at least 10 "F"-radars (my personal estimation).
2) "No Squawk" (see screenshot). Mhhh? Very strange...
3) From the same particular radar I saw at least 3 comparable "strange" AC-flights during the last hour. In the screenshot, however, I "blacked out" the number of the radar, because I do not want to declare this particular feeder as "feeding fake flights intentionally" - maybe it is just a technical problem of this particular feeder and the person behind it has no knowledge of the fake data "his" feeder is obviously producing.
4) No "GPS altitude" shown (see screenshot). This is - usually - the case for MLAT flight data. But: With MLAT flights we usually see "MLAT" (or "MLAT1" in this area) as the spotting radar, but not a particular radar (like in this screenshot).
Questions:
A) How come, that such (obviously fake) flights are published on the FR24 website? Is there no "cross check" of other radars' feed data within the FR24 system?
B) How should comparable obviously "fake flights" be correctly reported (in the future)? Intention is uppermost not to accuse particular feeders for delivering fake data, but making the FR24 system robust concerning fake data feeds.
C) After all: Maybe this is NOT a fake flight. If you think it is a real flight, please post this here including your arguments. I am willing to learn.
BTW: Happy Christmas days to everyone reading this posting.
