Vasi / Papi
Gentlemen, I would like to call upon all experienced pilots to help settle a debate about PAPI and VASI. We are in agreement that at larger airports these facilities are generally tuned for B747 aircraft. What we disagree on is when smaller aircraft are on the approach (ILS autoland or manual on the glideslope) do you see two red and two white ALL the way down (Down to DH). You inputs will be much appreciated as we have exhausted our trigonometrical analysis with no resolution to our debate.
