    Anything to avoid 4 digit callsigns, they are awful. Even the attempt to change how they are spoken e.g. instead of 4 8 6 2 use forty-eight sixty-two is only a half measure to avoid numeric dyslexia.

    Unless they have re-programmed the TAAATS system since I left, you cannot have two flights with the same callsign (flight plan) active at the same time.

    I often see flights with the D appended to the flight number. I thought it was to do with the flight being delayed and as there is a possibility of the usual flight also being in the air much later, the delayed flight has the D appended so that you do not have two flight numbers in the air at the same time. Giving the delayed flight a new flight number causes great confusion for waiting/connecting pax, so the D while signifying a delayed flight for the original flight number.

    The only Qantas flights I've ever seen with a D suffix are those operated by Dash Q400 aircraft as distinct from the smaller Q300 and Q200 versions that Qantas also operate. The Q400s are actually operated by Sunstate Airlines, the other Dashs by Eastern Australia Airlines. Both of these are wholly owned QantasLink subsidiaries. QantasLink itself is a Qantas subsidiary! It's got a lot to do with salary levels and you can probably guess that the highest salaries are not generally found in the subsidiaries.

    Like Air New Zealand I don't see the need for QANTAS to use alpha-numeric callsigns and believe the suffix "D" still remains an indicator for a delayed scheduled flight. ANZ also use this suffix.

    This mornings A380 from Sydney to Dubai is using the new format callsign UAE8JH and flight number EK415 while the Melbourne - Dubai service hasnt changed. Interesting as the scheduled and actual departure times were identical. They are currently playing follow the leader across Western Australia.

    I have my aircraft labels set to show callsign on the first row and not the flight numbers as many of the light aircraft apparently haven't configured the callsign field and it comes up blank. What do other feeders do ?

    Not really that novel an idea. In the UK, many moons ago, there were frequent issues with BA intercity shuttle flights using calls like BA4682 BA4826 and so on. The resolution, which I think may still be used, was callsigns such as SH6T (Shuttle 6 tango) with the 6 for the London-Glasgow and various other numbers (I cannot recall the rest) for the remaining London to provincial city flights. For some reason there was never a Shuttle 1 Tango.

    No info about that flight but in case you have not come across it, a lot of blocked flights that overfly Brisbane can be identified on SEQ Radar. Just Google those words and you'll find it. It's a tracker a bit like FR24, run by enthusiasts but with a limited range over mainly SE Qld /NE NSW. There is no playback facility as far as I know so you have to pick up the plane live while it is within range. Very few aircraft except combat military types and law enforcement are blocked.
    I have to wonder why anyone wants to have their aircraft appear as "BLOCKED". Nothing is more certain to draw attention to that aircraft and given that there are any number
    of sites that do not filter aircraft, its easy to find out what it is. Who worries about generic aircraft eg GLEX they draw little attention and by at least giving the type it satisifys
    the interest of most observers.
