I was never trained where to aim for, just assumed and went for the big squares and PAPIs (400 mtrs at 98 % of my airports of first 8 years).
Hope nobody teaches using the aiming piont markers located at 150 as that will result in 8 feet wheel clearance. (no-flare geometry)
If you or I end up doing exactly that (at absence of active understandig what the location and meaning of the markers is), here at JSI the wheel pass approx 27 feet over the edge of the paved surface (turning loop). Which actually covers for the compromised aiming point by the virtue of airport design.
The road itself is little further away and has lower elevation, please check.
