Planes go far past destination, then disappear from map

#1
I was watching two flights today enroute to FCO (Rome). The display showed them flying far beyond their destination, then they suddenly dropped off the map. (LH1850 and AZ1320). If the map shows real data, how is a situation like this possible?

Hi Chuck,

Sorry about this problem.
This happens when we don't have ground level data from an airport.
This when combined with "Move Planes" in Settings is causing the problem.

The Move Planes (or Estimate Positions on the website) is designed to calculate positions based upon last know position, heading and speed.
It is designed to fill gaps between data updates.

When coming in to land planes can disappear from range of our receivers as is happening at FCO I think.
Our estimations can then project their position inaccurately. After a while they will timeout and disappear from our maps.

We are looking for a data feed or a location for our own equipment near FCO.
Please let us know if you know anyone that can help with this.

Regards,

Mark

Hi Chuck, ;)

I agree entirely with Mark. :) Without a data feed close to the ground, this is what may happen together with 'move planes' setting in the settings box. It can be a bit confusing sometimes! Just wondering if a similar problem might occur if your network connection temporarily crashes?

I have been experiencing a similar problem with the planes at Adelaide International Airport. A plane without data can fly as far as Kangaroo Island before finally disappearing of the map. It had been good a few days ago when the ground coverage at the airport was functioning well. Then it just stopped... :eek: I do now understand a bit from the discussion "Ground Coverage" discussion I posted on Pinkfroot (http://my.pinkfroot.com/forum/topics/ground-coverage) that obstacles can restrict the coverage an ADS-B reciever can pick up. Hope the coverage at Adelaide Airport comes back soon! :cool: Good luck also with the coverage at FCO!

Hope this can help! ;)

Got a screenshot relating to this problem. Can be a bit confusing at some times! :confused:
Flying Right Past!.JPG

The picture shows VA233 flying straight past Adelaide International Airport at cruising altitude! :rolleyes: And landing at 739km/h!? :eek: The plane then suddenly changes position, course, heading and speed all at once, showing as the plane is on its final approach. I hope people using Plane Finder don't get confused by glancing at the clouds expecting to find a Virgin Australia B737-800 flying overhead! :( Hopefully more people share data and provide better coverage soon! :D It wasn't like this before the feed may have been obstructed or had crashed. :)

I know that we can't do anything about this until more people volunteer to share data with Plane Finder! ;)

Just to add to the amusement.
Planefinder has just tracked VT AKU from Mumbai (it is based there), the correct picture of the a/c was shown (correctly in Reliance Industries colours). It was labelled as 'Air Tahiti' , I can't imagine why as no flight number was shown. It tracked over my position at 25k, clear blue skies but I couldn't see or hear it. Seconds later it vanished off the map.
It didn't appear on the SBS either, but my antenna is not positioned well and bizjets often don't.
Have fun
Terry

VT AKU departed GOI a few minutes before 14.00 local, so track was close but not correct.

Hi Terry,

That is all a bit odd!
It sounds like we didn't match the callsign to the flight number properly.
Did you happen to make a note of the callsign?

Cheers,

Mark

Hi Mark
Sorry didn't notice one. Reliance seem to send one of their bizjets from Bombay down to Goa quite frequently
(VT AKU was in again today), so will look out for it, and let you know.
I'll contact you about (hopefully) contributing data in a week or so.
