misd-again, yes...I got that indicator one sideways..
With the .52 designs, the 140kts is for the entire final section, typically at least a 5nm segment....so if you have a turn that ends at the FAF, the curve is designed with 140 +winds, so one can start to see how difficult it is to get an 800 to 140kts 8 or 9nm out....and who wants to....
I know that quite a few procedures have been re-worked that were originally designed with the 737-400, and the 7/8/900 series just cant make the turns with stab flight.
