    Thanks fungus,(and all) this all helps me and I understand most of it. I think it was just the point that no ATC radar is used that threw me. I'm retired, however worked 35 years in the Aviation Communications realm, so have had
    some opportunity to understand the system. I also am a FR24 volunteer member with FR24's ADS-B equipment. Appreciate the links. As far as I am concerned this case can be closed. Cheers All./Bill

    Bill,

    This link may help;

    http://en.wikipedia.org/wiki/Aircraf...ay_to_Industry

    The following link may also help those who want to understand why and how aircraft are 'Blocked' from display. It may be posted elsewhere and if so I apologise but havent located it;

    http://www.fly.faa.gov/ASDI/asdi.html

    Aircraft blocking is however covered elsewhere on another thread somewhere so I wont go into it further here. Suffice it to say that some aircraft are blocked (both our 'receiver' aircraft and FAA) and therefore not 'visible' on FR24.

    Regards,
    Gregg

    FAA feeds appear as orange icons if enabled. Only cover certain areas of the world and are delayed by 5 mins. This still does not include smaller aircraft ill equipped with ADSB capable transponders, it is simply to cover more parts of the globe where FR24 receivers are lacking and its not a form of 'capture all' feed

    Thanks Mike. I was under the impression that data from FAA (and I assume in Canada, Nav Canada) was radar data? In 'about FR24' it says :

    "In addition to ADS-B and MLAT data, we also get data from the Federal Aviation Administration (FAA) in the United States." Can you kindly explain this.

    Cheers/Bill

    FR24 has no connection to any ATC radars.

    Thanks Mike, I was more or less aware of that but was under the assumption it would still have ATC Radar following and therefore show up Orange? Appreciate your time./Bill

    This is a Dash8 aircraft so it does not have an ADS-B transponder so it can't be tracked by FR24 receivers. For information about visibility and coverage please read http://www.flightradar24.com/how-it-works
    FAA is not providing data for this flight.

    Can't locate tis aircraft

    I am looking for Westjet Encore aircraft, in the air at the present time, ident WJE3242. When I type that ident into the search box top left hand side of screen, it does come up on screen but seems to hover around
    the departure station CYYC and then eventually heads towards the destination however I am not sure it is working properly as I tried earlier and the aircraft made a quick trip to the destination station, even though
    it does not arrive for another 25 minutes. Can someone else please check this for me. Thank you.
    PS: I have had this trouble with this aircraft previously also.
Working...
