Scandi...calm down cobber, you WILL note in my post that I did indeed make reference to the PDC procedure as laid down in our truely awesome manuals, it was a sarcastic play on the Ozzie predilection for believing their own BS, but it was a reference none the less, apologies for not being clear.
I agree with your points 1-2-3, but there is always the exception..."DXB app EK XXX 77W passing 8500"
"EK XXX confirm you have Hotel QNH 1002?"
"Affirm we've got hotel, 1002"
Thats one more call than there need be IMHO.
