Auto ILS
I flew the 'best' Aircraft in the 70s and remember the Auto ILS worked very well, though it wasn't purely Auto. The system worked well and produced a smooth approach. However, you did have to control speed with power as the Auto throttle function had been disconnected (spares? / didn't work?). I have a feeling, my memory is not that long, that the speed limit was something in the region of 180 Kts - I'll have to go in the loft sometime & dig out the Pilot's Manual.
On a final note, the Aircraft was much more fun flying everything manually. In fact it was my time on the Vulcan that caused my decision not to go to the Airlines; although the 10 West rule etc was fun as was the going to exotic places, those high level transits showed me the utter boredom of hours of Autopilot flight. Some of you will, of course , beg to differ.
