Well said, PJ2, as usual.
I want to clarify that I have been telling what we did in the past. I am quite happy that my current steed does auto-NPAs as well as the rest, but I also keep current in the old ways in case the box has a fit.
I also believe that timed descents/calculated VS are not the best way to do NPAs if you do not have VNAV, but, horses for courses, there are a few ways to skin a cat.
The Asiana crash , even if it had the ILS, probably would still happened as the basic requirement of sufficent airspeed was not present.
I doubt it; GS capture would mean speed with thrust, not pitch, which
appears to be their undoing.
