Thanks Lou for that lesson. I did not know, that you go for 3 white in a big bird.
And I´m pretty sure that FSX models both, PAPI and VASI. I think I saw VASI somewhere in Australia in FSX and I think it was an option when I created the Runway for my modified EDJA Airport many moons ago.

But as far as I recognize, FSX does not model the pink colour in the VASI... only Red and White like you have it at the PAPIs.
