Well quite simple really.
I have read and believe understand read back requirements yet every flight into Darwin I am asked by ATC to confirm or require a readback an item that is not in AIP/Jepps and is certainly not required anywhere else in Aus.
Maybe in Townsville or Willy but no major destinations.
I have to assume that Darwin has its own readback requirements and hence I am wondering where I might find a copy.
Had some of the best vectoring to a 7nm final I have ever seen the other day. Boy these guys are good.
