Just starting my fuselage so I probably shouldn?t be even thinking about avionics, but here I am sitting here thinking about avionics. After doing some searching, I?m left pretty confused about the design of a glass panel system, particularly about how you know what components you need given your airplane?s mission. There are so many components and options, and many products? capabilities seem to overlap.
Let?s say I?m intending to go VFR only and I want a GPS. And we?ll pick a vendor: Garmin. So these guys have their G3X touch displays (GDU 450/460/470) which have VFR WAAS GPS. Great! But wait.. they also offer a GPS 20A box also with VFR WAAS GPS. I guess it?s different because it can be used with ADS-B out. So would I need both for ADS-B position out? But then wait?they also have this GTN 625 which also looks like a GPS display but it?s massively more expensive than the GDU. What am I getting that I don?t with the GDU displays?
And this is just one product (GPS display) out of one product line (G3X) from one vendor (Garmin). How do you guys start out navigating all this information? Is there a beginner?s guide somewhere? Any advice?
