    VH-VJE and VJN: Where do they go?

    Each morning, Dorniers VH-VJE and/or VJN depart Brisbane (Australia) airport and fly west about 100 kms to a point roughly to the east of the Bunya Moutains, then turn around and go back to Brisbane. Anyone know what they're up to? I'm most intrigued as to the purpose of these flights.

    Hi Mike:

    Thanks for this.

    One other question: RAAF KC-30s from Amberley have civil call signs ... but I've never seen any for the C-17s. Both are regularly over us here at Highfields, but only the KC-30s show up on Flightradar. Same with helios from nearly Army Oakey (and never any F-18s). Is there a reason for this?

    Making another trip as I type

    Tankers aren't too civil. 'DRAGON' Go from SQN 33 http://en.wikipedia.org/wiki/No._33_Squadron_RAAF and I think have to be identified do make sure they are well seen when doing operations in civil airspace. F18s, for obvious reasons have to remain stealth and after refuel at low level often don't fly in commercial airspace

    Same with C17, operational movements are classified most cases

    Every 3 months, VH-FIX is in WSSS doing calibration of Instrument Land Systems of Changi, Seletar and Pulau Batam ( Indonesia ) sirports.

    I know it's an old thread but just wanted to correct a bit of wrong info. These Dorniers ply between Brisbane and Chinchilla on energy industry business. The reason they seem to disappear is that they are unpressurized and only fly at about 10000 ft, hence they become invisible when they pass behind the Bunya Mountains because there are no FR24 feeders west of the range. BBN1 and one of the two feeders in Toowoomba provide the coverage you see on FR24. Although the planes appear to just turn around and go back, they disappear for a while while they land in Chinchilla then reappear going in the opposite direction at the point where they disappeared. This appears to be a mapping error within FR24 but is neither here nor there in terms of practical importance.

    Not a mapping error. It can't plot what it cant see. As the callsign doesnt change to indicate a to/from flight the entire length of the path is displayed, which happens to fall short of its destination using a similar path.. so it appears as a loop

    Yes of course you're right. I've seen the same effect on much larger freight planes that sometimes fly around the world on the same callsign.

    Thanks guys, this makes sense. Also, pity we can't see (over the Pacific and the Indian Oceans, and over the Tasman Sea) the oceanic tracks of aircraft (like Fligh radar shows for those over the Atlantic). Any ideas?

    Most of what can be seen over the Atlantic and northern Pacific comes from the American FAA feed which does not depend on radar exclusively - in fact a lot of info about trans-ocenanic flights comes from radio messages between pilots and various ATC centres around the world. The only way that FR24 coverage could happen in the south Pacific and Indian oceans would be for people to put up feeders on islands. There are suitable habitated islands in parts of the south Pacific but not many in the Indian. There are feeders in Hawaii and New Caledonia (currently not operating) and supposedly one at Fiji but I've never seen anything from it. Someone in another thread suggested Lord Howe and Norfolk islands - would be great for Tasman coverage if anybody in those places is willing and able. There are some interesting flights between Australia, NZ and South America but they fly a great circle route through the southern Pacific and there are almost no habitated islands down there so they also will never be visible on FR24 other then when they arrive and depart from Oz, NZ, Chile and Argentina.
