There were other satellites at Warracknabeal and Edenhope as well as numerous farm strips which were utilized in an emergency, an all too frequent occurrence back in the days when men were men and sheep were nervous.

    I didnt mean to frighten you mate, I just saw the YDMB and the YHNL and couldnt understand the discrepeancy. We've had quite a few odd radar codes and I wasnt sure where the mistake lay. I certainly wasnt having a go at you or anybody else.

    And as I said before, greetings to you too. Cheers and beers, as you say.

    It's Dubai http://www.flightradar24.com/25.26,-304.63/14

    My browser (chrome on w7 pro x64) is showing it correctly.

    Though AIR15 seems to be the type of track I get from my GPS logger driving to work - following roads in from the suburbs, through junctions etc (neatly avoiding buildings)
    I'm not ruling out an occasional server cluster sync prob..

    Cheeky but yes, as with NZCH where the intl's flow in after about 2200-0100 theres a 1hr period daily where NZAA gets 3 EK A380s back-to-back, and add to that the domestic and extra air-freight (PST) flights.. it can be busy for a few hours at a time during the day with ground staff and security patrols too

    Sorry Wal,

    I didnt mean to frighten you mate, I just saw the YDMB and the YHNL and couldnt understand the discrepeancy. We've had quite a few odd radar codes and I wasnt sure where the mistake lay. I couldnt find either ICAO code so my head was in something of a spin. I certainly wasnt having a go at you or anybody else.

    And as I said before, greetings to you too. Cheers and beers, as you say.

However there is one thing that I did neglect to mention in my earlier post, and that is the Lat/Long indications for individual A/C. In almost every case, whenever the 'glitch' occurs, the last two digits of the coordinates have been dropped; for example 25.2448/55.3695 becomes 25.24/55.36 respectively.

    So unless you zoom right in they will always appear to over-lap as it can't pinpoint to the seconds/metre location on the map at that height.

    The other issue may be the ground uploader is sending bad data. Dongles are known to do this if too close to the source and need error adjustments made

    I think the grid (if it's just one locality) might be rounding errors on an feeder computer - small software problem

    If it's everywhere - it's FR24 (sh*t happens, though it shouldn't)

    Yep, my initial thought after seeing it was possibly a default 'home' or similar old data that is used when an active updated packet is missed as they kept bouncing back/forth to it

    What would be useful would be to click some of them and to read off what radar has uploaded the positional information from some of those 'wrong' planes. (I would do it but I don't know what airport the image is of).
    psst... I included it was NZAA and 2 radars that were displaying it in the end there

    I don't think it's anything wrong with your browser, much more likely to be a local example of 'garbage in (from a feeder), garbage out (from the web site)' .
    Yeah, included what I was running as secondary information since the OP mentioned he had chrome. And we all know how bad IE is in any case..

    ...and with a site like this moderators are needed to give 24/7 coverage - it's an unpaid responsibility that keeps site like this free of porn and third party advertising - that there is so little here it shows what a good job they do.
    There's a lot less here nowadays with the added security, but like most things the odd one gets through. Usually actual paid people.. nay people with "far too much time on their hands" (that actually get paid) who sit in an office and join forums manually posting them instead of bots. Can usually spot them as it takes them 1-2mins between post times and dig up old threads with key words.

    Whereas my mention of the bad upload data from dongles did, so I re-quoted to point out I had already included a plausible answer to the second half of his query.

    By quoting me and then adding your own weekend experiences only says to me "you're wrong.. cause I saw this.."

    Your given examples in this case would have been better to have been added to a thread on said weekend if you have seen some examples the last few days for the dev team to take note or added here without openly quoting my post.




    No, It sure isn't the the way. It's by being an active poster on the opposite side of the planet to the main admins, and attempting to assist people with issues in a methodical manner, eliminating apparent multiple issues/causes bit by bit rather than writing the whole system off as being at fault for the whole part like many are keen to do around the forums at present. And keeping the bots at bay.
    You are wrong on all counts - the issue at Sydney affected more than a single feeder - the implication in your original post is that there was maybe a maladjusted feeder present. It is not an issue that caused me any concern or inconvenience at the time I spotted it - I expect that it will eventually right itself - and I have only commented today because someone else posted about a similar problem elsewhere. You and a few others here obviously have far too much time on your hands to be able to churn out endless verbage apparently just for the sake of writing it. It is not mine, yours or any other user's responsibility to be 24/7 troubleshooters for the operators of a commercial website that I for one pay money to use. Keep this trivial matter going if you want to but I won't engage further with you.

    Much like this..

    Attn Mike/Devs/FR24Support

    Further to the OPs queries I have just seen one of these phenomenon's occur myself:

    Premium status: logged OUT
    FF v25
    0740 UTC over NZAA region

    (http://oi42.tinypic.com/2zp2is3.jpg)

    APRT12 (which for some reason is now marked as a fuel vehicle..) was doing its normal perimeter patrol, but then the track was straight-lined for a bit from the centre location where the other AC (JST250 and PST42) appear here, Later moving to other parts of the airport at each 8 second update

    Contact was distributed between NZAA2 and NZAA8, both T feeders
