Hey Mauleguy, the requirement is in the FAR. as 14 CFR Part 91-314. The FAA doesn't send announcements of regulatory changes to each aircraft owner, they just expect you to know and follow the FARs. Besides, if you don't fly in any of the airspace where ADS-B is required, you don't have to have the equipment. The FAA doesn't keep tabs of where certified aircraft fly, so they have no way of knowing who will need it and who won't. The rub will come in 2020 if you want to fly in airspace that requires ADS-B-Out and you don't have the equipment. Remember, the FAA doesn't have to follow criminal justice rules. For "aviation safety", they are the executive branch regulator, the enforcer and the judge when there are disputes. There isn't any good way to get sideways with their regulations and come out unscathed.
I saw the video about this product and it is clever, but I wonder if it will be certified in time for installation on production aircraft. The FAA estimates there are still 125,000 certified aircraft that will require ADS-B that don't currently have it. For all of those aircraft to comply will require 3,906 installations of the hardware per month between now and the deadline. Current installation rates are 1,500/month. I'm not sure there will be enough avionics shops available to complete all of the installations in time if owner/pilots delay much longer. I signed up for a weight neutral installation. I'm removing a Garmin 327 mode C transponder and replacing it with a Garmin 335 mode S with extended squitter. No new antennas are needed because the WAAS GPS source will come from my 430. There were less expensive options available but all of them required adding the weight of a separate box and an antenna. The installation costs were higher for the less expensive hardware options. I made my 20% down payment in February and the earliest dedicated date available for installation was in July. That is a 4 month waiting list! I got in earlier by agreeing to leave my plane with them for a week so they could work on my simple installation between other jobs.
This is coming whether we like it or not and some of the innovative solutions being developed now may be too late to cover folks that live inside a current 30 mile mode C requirement veil. I fly into a Mode C veil regularly, I fly through Class C airspace and I sometimes fly above 10,000 MSL and more than 2,500 AGL. All of those flights require ADS-B-out by January 1, 2020.
