The ICAO number in the GP's comment is listed in the FAA registry for the N-number: https://registry.faa.gov/aircraftinquiry/Search/NNumberResul... (Mode S Code (Base 16 / Hex): A835AF). Are you saying that PIA program can make registry.faa.gov report data that's either obfuscated or out of sync? Why is it not reporting such data now? (Edit: Or maybe GP's comment is using a non-privacy ICAO number and the actual number squawked is private?)
