True. 62ft equates to a ground point of intercept of 360m; however, the distance between the PAPI and the threshold is 278m, according to Google Earth. Even given the errors in a non-vertical satellite picture, I can't see how 62ft could be close to being correct.

It also looks like the GS ground antenna is around 255m. From those Airbus figures, that would put the GS antenna over the threshold at 44ft, wheel height around 17ft.

Looking at the 747 video, they were 4 whites at the minimum and pretty much on GS. Given the glideslope would well below the PAPI if it was at 62ft, you expect to see at least one red.
