What Will said.
Also, for pilots flying in, take a look at the new ILS RWY 25L transitions.
http://155.178.201.160/d-tpp/1705/00237IL25L.PDFIf you have one of the newer AIRACs, you should have the new ILS RWY 25L IAFs. (If you have the ANJLL1 or HLYWD1 arrivals, you've got these.)
There are three IAFs used on ILS runway 24R and 25L approaches for arrivals coming from the east: CRCUS, SEAVU and CLPUR. The ANJLL and HLYWD STARs feed to CRCUS and SEAVU. You'll likely hear this from your approach controller: "Descend via the ANJLL1/HLYWD1 arrival, at SEAVU/CRCUS, cleared ILS runway 24R/25L approach."
Now, specifically check out the new CLPUR IAF (initial approach fix). If things get busy, your friendly approach controller may let you know to expect CLPUR for ILS runway 25L approach. You should continue the arrival, but setup your FMS to take the CLPUR IAF. You'll get instructions on when to proceed direct CLPUR and be cleared on the approach.
Why? The CLPUR IAF moves 25L arrivals a little further south. This keeps them separated from 24R arrivals so they can be run side by side. This means more efficient flow for everyone.
Let me know if you have any questions.
