That was really helpful as before. I appreciate it is difficult not to talk down to enquirers but doing so ensures that the picture painted is complete. Better to assume nothing!
I have been a lifelong yachtsman so am pretty happy with two dimensional navigation. I grew up in a world of Decca, Loran, Omega, DF radio fixing, DR, buoyage, compass bearing fixing, visual range finding, sextant, and eventually, GPS.
Three dimensional navigation is very similar except that there is a strong incentive to get the third one right! Up to a point, when sailing, you can stop (or at least slow down or hold safe position). I understand that is generally frowned upon in flight.
I wonder how the move towards GPS is viewed in the professional pilots' world. The various yachting forums I subscribe to, carry not infrequent reports of local GPS outages. Not disastrous in sailing (with forewarning and contingencies) but if air radio navaids are discontinued, that could be concerning.
Flying tuition is burdened with a huge list of abbreviations which are, initially, a block on assimilation of new skills. As an old git, that is a bit of a struggle!
The audio warnings are presumably a Boeing thing. Our holiday flights have nearly always been in 737 NGs and the local (static) simulator is based on that (approved for commercial training). That is why my "flying" is with this aircraft. I am fascinated much more by the technology than actually flying.
I believe it was Smiths Industries (my previous employer) who introduced auto land in association with BLEU (WIKI last line refers to SI although the link doesn't work!). The technology was frightening by modern standards. The autopilot used electro-mechanical switches (whose cute name I can't remember) and the "clicking" was both worrying and reassuring!
