I’m also an FAA licensed A&P mechanic, and have worked for airlines in fleet maintenance. Air carriers have extremely thorough systems reviews, by law, through the Airworthiness Directive program, which started identifying 2019 GPS rollover vulnerabilities in ... 2009! Nobody was surprised. If any GPS systems “went nuts”, it was through the incompetence and negligence of their owners.
How many GPS owners happen to have $30,000 GPS simulators to check their $300 GPS/NTP servers? Some of mine did, most did not. Seems to me the negligence is in the GPS manufacturer that failed to notify their customers. To be fair, Avidyne and Telit did notify their customers, but not with a fix or enough lead time to swap out the units.
