The same goes for MALSRs
, REILs, and other lighting arrays that are located on or beyond the runway threshold.

If your approach is an ILS or LPV with minimum visibility less than 3/4-mile, then it must have an ALSF-2 or -1, a SSALR or MALSR
Jeppesen lumps the MALSR
into the category "ALS out" in the minimums section.
The changes in the required visibility for an inoperative MALSR
that are shown on this approach chart supersede the inoperative components table found in the NACO terminal procedures book.
In the minimums section (or the briefing bar on NACO plates) you'll find that LOC Z requires the CH1TT FIX minimums to be increased for an inoperative MALSR
I'm used to at least a MALSR
guiding me to the runway.
In our case, "We have a MALSR
system, with a PAPI on the left side of the runway.
Runway Alignment Indicator Lights are an integral part of the advertised MALSR.
Although that's part of the rule, you must see other things to continue as a MALSR has neither.
The light setup is identical to SSALR but, because of the reduced intensities, this is called MALSR or "medium intensity approach light system with RAIL.
For example, to continue on a MALSR, you'd better see the threshold or one of the other items in the FAR 91.
