PAPI LIGHTS
Just a random question- is there a value or thumb rule where the perceived PAPI lights will change based on your ground speed or distance if you fail to follow the correct glide path? What I am trying to infer here is say, you're on the correct 3-degree glide path (visual or ILS) and PAPI shows 2REDS 2whites, and then a sudden increase, and constant Tailwind follows, assuming you don't compensate your VS for it, and don't bother to see the glide slope indicator slowing moving down. At what point or distance will the PAPI show 3whites and 1 Red or vice versa?
