Just as general interest and back ground but: how low are PAPI guidance lights supposed to take you? I have found in manufacturers blurb info suggesting that following 2R 2W down to as close as 300yds and roughly 15m to be accurate that, for a large aircraft doesn't seem feasible. From MDA/DA (substitute H as required) you're "in the groove" and at some in defined point transition to some sort of flare and landing attitude is going to happen such that you arrive on the black top in the touchdown zone. Crossing the threshold at a nominal 50' of course when you're main wheels are some 34 FT below you and perhaps the receiver aerial for the ILS and you're view of the PAPIs don't all match up......
Standing by for criticism for not knowing the answer
But also hopeful of some good he.......
