Flightradar24 question
I was tracking a Bizjet with known registration but private destination and owner details. I predicted the destination but it disappeared off Flightradar24 completely. Would this suggest security precautions due VVIP flight?
Thanks
Thanks
Maybe they turn off M-LAT or whatever under a certain altitude for their own reasons, whatever they may be ? I notice that certain aircraft are visible on some tracker, yet on others empty space. Who knows why, not me, but I'm sure someone will be along with a detailed explanation soon enough :-)
Tracking systems are a compete mystery to me. Remember being in Barbados a few years ago when FR 24 had some flights and Planefinder had others and some appeared on both. Never found out why.
Similarly last week in Madeira looking at Shipfinder, Cruise Ship Tracker and FleetMon to see what was coming into harbour and it was a compete arbitrary mix what appears on what tracker and occasionally 100,000 tones would appear with no warning at all.

Are you talking about MLat? Or ADS-B/Mode S in general ?
Perhaps the jet landed at an airport not covered by a contributor to FR24. At Teesside airport a contributor turns his equipment off so aircraft disappear once they get to a certain height.

Thank you for your replies :-)
Nothing to do with being blocked (in that case, FR24 wouldn't show the aircraft at all).
In my experience FR24 is not bad with passenger flights but poorer with biz jets and cargo flights. With the last flights often appear multiple times often with unknown against some of them. I don['t know if anyone knows what the problem is. It could be a lack of data from airline and airport sources and confusion with triangular (or more complicated) patterns where a sector may carry the number of the inbound or outbound flight.
The FAA have an option (LADD) for flight tracking data to be blocked on application, usually from owners of N-registered executive jets
Ironically, ADS-B, which states it does not block anything, has an LADD filter which allows the display of just these aircraft which are blocked by FR24 and other trackers.

When I looked a while ago Cloudflare was giving me a 7-minute waiting time for FR24 b before seeing the site and moments later I was blocked just like that! As mentioned they must be overwhelmed today as perhaps the most well known of the trackers.
On the right hand side of the adsbexchange.com display there are a number of optional filters. One will restrict to military aircraft. Another "LADD" will only show aircraft blocked by FR24 etc. This filter will probably only show half a dozen aircraft over the whole of Europe.
