The GPS sure has come a long way in the last 30 years! When I was working on my first instrument rating in the 90s, the GPS was more or less and experimental thing and not really certified for IFR approaches.
A friend of mine bought one of the first moving map GPS’s out there (I forgot the brand). It came from the helicopter that flew around the world and he was able to get it second hand and put it in his Jet Ranger. It had a gigantic box in the baggage compartment that used floppy discs to update the data base every two weeks. And it must have weighed close to 200 pounds total, turning the 5-seater helicopter into a 3-seater pretty much, lol.
Over the years, the screens got bigger, the units got smaller, and lighter, and gained really cool features. Naturally, the manuals for these smaller units with more features grew with all the added capabilities. I feel, that even though the Garmin product is fairly intuitive to use, the manuals are not all that easy to read for me. It’s almost like you have to have somebody show you a few moves first to get started. And now that they have LPV*, LP+V, and all these other navigational and IFR capabilities, the FAA started requiring more and more documents being kept in the aircraft. I was laughing at the gigantic package that was required to be kept in the aircraft when I got back into instrument flying after a 20-year break. And so, another comic strip was born…
*) LPV = “localizer performance with vertical guidance”
