Gives a A330-300 eye to wheel height of over 10m.
By my calculations, on that runway, with an assumed PAPI angle of 3° located at just under 287m (giving a MEHt of 49ft), the wheels will cross the fence at 12ft and touchdown, with no flare, at less than 50m in. And that is on 2W2R. That is why they install "big jet" PAPIs with a MEHt of around 65ft.
Anybody thinking a 777 is the same as a 737 is this scenario is, IMO, mistaken.

Made more difficult when the PAPI "encourages" your mains to be only 12ft over the piano keys.
The 330 may have great brakes; it's where the PAPI leaves you which is the problem.
