If the airport/Jeppeson would inform us about the set-up of the PAPI's i.e. the TDZ distance in, we could make a reasoned pre-approach brief about what to expect. But they don't.
They do 'ere. Meht for every PAPI/TVASIS installation in the country is published on the 10-9. Not as easy as giving the actual TDZ distance in but will give a good idea. A simple Excel will give you the distance. Otherwise, look where the PAPI boxes are relative to the 300m markers.
