On Guard
"Another question - What happens in AU if you are given a direct GPS track. When you change freq do you say "Centre XYZ FL250 direct XXXXX?" In NZ if we have been cleared direct we say this, otherwise if on FPR just standard call."
I fly direct GPS tracks regularly. When changing frequencies I just give them "Centre, XXX maintaining 9 thousand", for example. I have never been asked for any more. An eroute controller in here could give us the drum, but I think it is clear from my clearance and their software that I am on a direct track from A to B, even though A might be 562 (for example miles from B.
What I always find amusing though is when I drop off radar and then get re-identified -
"XXX, Brisbane Centre, your identified 347 miles south east of (Destination)"
I would be curious to know if I am legal flightplanning direct tracks over long distances using GPS RNAV rather than following airways, but I have never been chatted for doing it.
