PJ12:
The PAPI information is not on the Jepp Airport chart. The info is on the approach plates, just below the profile section.
It certainly is, on the 10-9A page, not the airport diagram side but the side with runway info and takeoff minimums. If the PAPI or VASI has limitations as less than standard distance or less than standard beam width, that info will be shown on the "takeoff info continued" page (usually the 10-9A page).
The info on the approach chart does show the PAPI and ALS, but is quick-reference info as opposed to the airport/takeoff pages.
