IVA Sydney

Question for the SY ATC team regarding parallel ops and crossing assigned runway centre line, When IVA and ATIS has

"do not pass through assigned runway centre line"

when we are vectored on a base leg and for whatever reason the heading for final is not given, are we required to turn on to our assigned runway without clearance?
I have had this discussion many times, Ill usually arm the LOC (I know we can’t descend past the last clearance level) when on base as a threat mitigation as id rather not head for the 380 on the other runway, this usually leads to a the other crew member stating "we are not cleared for the approach"

The answer is yes, and its an independent visual approach NOT an independent LOC approach.

The ref to LOC armed is to capture it to prevent crossing CL; not to perform a LOC approach.

SHVC,

That sounds to me like a damned smart risk mitigation, arm LOC so you will not pass through the CL. As you say, descent is not cleared yet so LOC is the go.

The reason that the phrase is on the ATI is because pilots have allowed the LOC to capture and when it doesn't or is late in doing so, BINGO its no longer an independent approach. Aircraft too fast on base, aircraft not correctly flying the intercept, aircraft not flying an independent visual approach had led to increased R/T and the phrase on the ATI. Perhaps I should bang on about CASA and AsA not educating the pilot bodies.

The answer is yes and it is spelled out in the Sydney airport charts.

Good question and good on you for asking SHVC. Made me a little bit smarter now as well.

Here is the relevant passage:

Commence the turn to enable intercept of the final approach course for the runway assigned, then track the extended centreline of the runway assigned.

Because that would increase the load when it's obviously busy.
Nothing wrong with a handfly, time and a place etc
What's wrong with LOC?

IVA only? What about ILSs?

Unless ATC advises an expectation to pass through CL, you should turn final as per the posts above. Check the IVA user guide in DAP-E. Bear in mind the LOC isn't protected during IVAs. GLS better if you have it.
