I have to say that when I have operated into DXB that I have found simple R/T discipline to be lacking. Not only from pilots but also from some of the controllers. Often clearances / readbacks are given without the callsign being part of the clearance.
eg " EK 201 cleared to line up behind the 737 on final"
" err Sorry Tower confirm cleared to line up "
" affirm line up behind the landing 737"
Problem is some Illlusion or any one also tunes in at the second sentence
( or us on the day i heard this) and only hears "affirm line up behind the landing 737". Off course we questioned it , but its open for incursions.
I must say not an isolated incident , I encourage the DXB ATC,s to have a listen to the tapes and see just how often the callsign is omitted from transmissions ( Pilots and controllers alike) it will be astonishing !!
