FlightPathOBN:
I am not skeptical! I am cynical! The ADSB system is already over 50 years old. A 'new' system of ADSB in and out is still based on the same signal, protocal, and syntax. That is why I feel that by 2020, the system will be hopelessly outdated in terms of software, electronics, and the aircraft that use it. We already know that a passenger with an internet connection, can see all of the ADSB aircraft on flight aware, while the crew cannot?
Have you written about this to the FAA Administrator, Congress, Aviation Week, and the Washington Post?
