So your saying the last 50' of the approach would invalidate landing distance calculations? I'm not so sure if I agree there, besides if you touch down before the lights, surely LD calculations are valid? That's the whole point of having those lights.
(correct me if I'm wrong)
wo ping's comment about the last 200' of the PAPI's being unreliable seem's to ring a bell from somewhere
"i.e. at LCY you are further below the glidepath with 3red 1white – closer to the obstacles, than for a 3 deg approach"
PAPI-74 isn't talking about flying the whole 5.4 miles below the glide here! Just the last 50' or so, and being over the runway surface at this height, how many obsticles are you likely to encounter?
As an F/O I don't get to land into LCY, so I really can't qualify my observations, and I guess it is just down to individual technique and A/C Type
Happy Landings nontheless!
