Below is a screen grab from the ILS RWY 25R approach chart for HKG/VHHH. What should the plane do after passing SMT radial 084 (or TD D8 NM)?
It doesn't look like immediately turn heading 253 degrees; from an algorithmic point of view does the plane do an RNAV from PLOVE to RIVER, then track SMT radial 253 after RIVER? Or does it start to track SMT 253 right after SMT radial 084?
Also, what does "ITFR" stand for in this graph? The ITFR distance measures from the east and west side of the runway are based on two different ILS localizers, is that correct? Thanks!
