If in FAA airspace, there is a FAA Information For Operators letter (InFO 11009) on the subject. KLAX is semi-famous for the ILS approaches having very long segments with numerous stepdown fixes prior to the final segment, on the order of 25 nm. Follow the glide slope and you will bust several of them and they are, in somes cases, for terrain/obstacles. The technique is to arm APPR, upon interception of the LOC return to NAV mode so the A/P won't follow the the glide slope until APPR is rearmed. Your plane may vary but the idea is there.
Google that InFO, if interested.
