Just as I thought, wishful thinking. I have an experimental registered glider and I'll just wait a while to install a transponder.



It's very unfortunate that FAA has strayed so far from the original vision of ADS-B Out so small and inexpensive that portable units would be carried by skydivers and hang glider pilots. The system integrity requirements for ADS-B Out are ridiculous when compared with the current system integrity requirements for mode C. Any approved glider logger with integral baro sensor is capable of producing position and altitude data with integrity at least as good as the altitude data of a mode C transponder with separate encoder.



Another good idea killed by excessive regulation.

Small portable units is not where the vision of ADS-B started, and was clearly really never a significant FAA goal for ADS-B, its being driven as technology that enables NextGen, and that's been obvious for a long time. It was probably wishful thinking of some folks who kept promoting it as something else. Especially when those goals would conflict with other needs like NextGen.

Another idea that came from an extremely highly regulated/complex area and was really a pipe dream to hope it could be repurposed for low-cost uses.
