If a PAPI was calibrated to a 3 degree slope, would maintaining 3reds 1white make you land shorter or on the TDZ if you didn't flare(just for thoretical purposes)
I hope this one is answered
Would you still be flying a 3 degree glide path if you maintain 3R 1W.
Nope, maintaining that would give you a flatter approach.
Is it the same on a VASI and the glide slope of an ILS.
ILS is the same principle, yes. VASIs, since they are at two locations, one short of TDX and one long, complicate the geometry somewhat, but once you get two reds there is no predicting at all where you are and what you're doing.
If it brings you to the TDZ, then being 3whites on the PAPI shouldn't be problem since you will stll be ending up on the TDZ. Only your rate of descent will be higher.
Correct, for the same airspeed.
Also, if I am 3reds and maintain a normal 3degree rate of descent, would I end up being 4reds.
Yes, you would
ANd the same for 3whites, would i end up being 4 whites.
Yes
