Bushy- please believe me when I say I wasn't trying to cast apsersions on GA pilots (I guess when I fly, I am one). The post could be read that way. The post should be read in the context of FB's posts re; risks if the GPS signal is lost. The big end of the industry are covered, and we are talking about fitment to the GA fleet. I was trying to point out that pilots, full stop, shouldn't be navigating on GPS without any other clue, and so the "risk" in losing the GPS signal as per FB's scenario, is miniscule.
Fully agree that GA is undervalued, and maybe ADS-B fitment is a step in inlcuding GA in a more professional aviation system? As opposed to the "dirt road", backwards and exclusionary 'vision' vaunted by some posters here.
