ILS altitudes

[Booker]

Doesn't the depiction of the "Fan" on the approach plate have something to do with this? The civet arrival and approach to 25L at LAX have crossing restrictions that will be violated if you follow the GS too soon. The "fan" is only out to the marker and if you use that (as to when to follow GS, you're safe).

Without looking at chart legends, I'd say that's correct for Jepp profile views. The fan extends to the GSIA and is analogous to the lightning bolt on government charts. However, the length of the fan in the plan view is typically not coincident with its length in the profile view and typically extends beyond the location of GS intercept.
