The standard requirements (ICAO?) for lighting on an instrument runway is that PAPI matches the ILS GS; if not, this deviation should be identified on the chart. I see no evidence of this.
On the chart you link to, no PAPI is shown at all. But I can tell you that the PAPI is there, and it is
not aligned with the ILS GS.
The ILS threshold is displaced; this gives a LDA of 2610 m
Well, 2610m is not too much with the groundspeeds you get at an elevation of ~9200ft... runway behind you, and all that.
I guess what it all means, is that with the described technique you can use the entire runway, which is nice, but it is no longer an ILS approach. It is an ILS-letdown to a circling approach, and circling minima are used.
