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.
Good stuff! Guess my assumptions were too conservative (or not conservative enough).
