Our procedure is to transition to the PAPI at 9900 feet, deliberately flying beneath the slope (this is an approved procedure)
Correct me if I'm wrong but isn't this always true when referring to a CAT 1 ILS?
No, correct procedure is to follow the glidepath all the way to the runway.
For some aircraft ( like 747) papi is giving wrong info ( below a certain height) due to the distance between glidepath antenna and cockpit.
