Was flying into LAX with a very experienced Skipper who had retired from one of the majors last year ....we were cleared for the ILS approach 24R at 40 miles.His view was that the mass of subsequent minimum approach altitudes are no longer applicable as the ILS glideslope effectively became our vertical clearance.
Unfortunately on this runway the glideslope can take you slightly below some of these minimum altitudes earlier in the approach.
I pointed out the glideslope validity distance to ensure we followed VNAV and maintained all minimum altitiude until we passed the final minimum alt but can't find the reference which confirms that an ILS approach clearance does not allow you to bust a minimum altitude.
One old thread on here says
"Cleared for arrival = cleared for the path dictated on chart, do not descend without clearance
Cleared for approach = descent at your discretion while adhering to the altitude restrictions on your "path" and cleared to fly the arrival "path"."
...but with no reference. Thanks in advance.
