    There are various Canadian a/c that are blocked according to laddlist.com, and the Micronics.de site. They don't appear on the usual commercial tracking services either. But using the LADD filter in tar1090 only seems to show US registered a/c. I ran the ./update.sh script to update the ac-db but no change. What am I doing wrong? I've just switched from skyware to tar1090, so I may be missing something very basic here.

    As an example, tail CFGMQ (icao c01121) would be one such a/c.

    TIA. ...John

    LADD list comes from some FOIA request i think, not sure how often it's updated.

    Canadian aircraft are recent additions.

    Thank you. So just run that ./update.sh regularly and it should eventually sort itself out?

    I don't know if they'll appear on wherever the list comes from.
    Might work at some point, might not.

    Best of luck.

    I discovered a current list of LADD tails/call-signs which can be downloaded for free. It includes a/c from all countries, and seems to be actively updated. https://laddlist.com/download/ It's from Jack Sweeney, who is an (in)famous user of adsbx data. I might try updating the the .csv file that gets imported by that ./update.sh script to use the LADD flag from this other source. The db flag in that .csv seems to be 1 for LADD, and 10 for military, and 0 otherwise. Alternately, changing the ./update.sh to do this on the fly might make more sense. I may look at that if I have time. cheers.

    Well if we have a public source we can somewhat trust, we'll use it.
    Don't worry about it, coming soon (TM).

    Ok, found a bug when foreign aircraft are on US LADD list. Working on a fix.
