Quoted by AoA
As for localiser frequency I have been prompted a few times for not reading it back in Sydney. I see what you mean about it as a check but at the end of the day they are instructing you to use that runway are they not? As in they are checking that your ATC instruction for the appropriate runway has been correctly interpreted by you?
But they are also giving you the runway to be used. To confirm what SY APP has told you.
SY DIR: "descend to 4000 runway 34L, localiser check 110.1"
So to me that says that the localiser frequency isn't required but you have been given a runway and therefore that IS to be read back but the check is just that...a check. Perhaps I'm looking too much into it. I tend to do that with air law.
