“Yes; the mandate will cost me money, but having traffic in the cockpit, and seeing other traffic is priceless…”
While it’s nice to see SOME, maybe MOST traffic, ADSB won’t show ALL traffic unless and until all aircraft (those with electrical systems, and those without) are appropriately equipped. That would mean all lighter than air, and both new and antique aircraft that were never electrified, ultra-lights, drones, etc. etc. etc. would continue to be invisible to any gadget filled panel.
As far as reliable signal goes… I don’t suppose sat based navigation equipment will fare well if either of our peaceful friends in the far west or far east (both across the big waters) decide it’d be a hinderance for the Western world to lose ADSB and other stat based tools.
