The approach is designed to cross the centreline on the way to the VOR, with the MDA (or DDA if you like) occurring as the aircraft crosses the CL
Bloggs,
I didn't say anything different. The WTF was an explanation that the 737 VNAV will disconnect at the coded E/D at MA09, but the LNAV steering will remain to the VOR. With the runway/REILS in sight, you disconnect everything at MA09, ignore the steering, turn on to final, land and go to the bar.
My point was you can't use LNAV or VNAV inside MA09.
My question remains. What does 717 VNAV steering and auto-flight do at this coded E/D? Or do you know?
(and BTW for this approach it's 2.8 degrees and this will be displayed on the 737 legs page to enable approach geometric from the FAF, but the altitude at MA09 is hard coded and not 'computed')
