The FAA’s Notice of Proposed Rule Making for Remote ID goes well beyond just remote ID. I have not had time – yet – to read the entire proposal, but it does include a requirement that most all model aircraft be tracked in real time, once per second. Where “Internet is available” (which they mean 3G to 5G cell service), the position information must be relayed through a phone app to an Internet cloud database for real time tracking. They propose that third parties will run this air traffic management system and everyone will be charged an annual subscription fee. They’ve pulled a number out of a hat and say this might cost $30 per year (presumably PER aircraft); if this estimate is as accurate as the Affordable Care Act estimates were, then it will probably cost more like $100 per year. They will also change pilot registration to per aircraft registration, charging $5 per aircraft to be registered.
This is contrary to the recommendation of their own consensus of stakeholders advisory committee which recommend EITHER Internet tracking OR broadcast remote ID depending on the use and application. The FAA instead said it wants BOTH to be mandated. It is not entirely clear what happens when Internet is not available, and how they define that. If you have TMobile and no service, but Verizon has coverage are you required to also have Verizon service? While you can fly without Internet service such as in remote lands, there may be enforced restrictions such as a 400 foot horizontal limit (enforced by the certified quadcopter controller).
