Following alphacentauri's post, the timing of the mode change is actually a minor issue for aircraft I fly. All the approaches listed above look quite easy to fly (much like YSCB Rwy 35 off the Bungo 9 STAR for that matter), but we cannot identify LOC or DME beacons until after the RNAV display has been removed from the HSI.
So the mode change on an RNAV - ILS approach involves about 30 seconds of manual flying, or HDG-VS modes, as we turn onto the approach. A stick-and-rudder non-event, certainly, but the pilots must think ahead to manage navaids as we turn onto the ILS, given that other things will also be happening at that time. With more modern aircraft, it would go from "takes thought, but no big deal" to "do nothing".
it's not necessary to "over-think" and make the procedure more complex than it actually is
You obviously don't work for my employer...
OBN, you're embarrassing yourself with this talk about MAPts and LOC approaches. Slide your seat back a couple of notches and relax!
