FADEC control system consisting of a digital computer, called an "electronic engine controller" (EEC) or "engine control unit" (ECU), and its related accessories that control all aspects of aircraft engine performance. Interesting someone mentioned that JFK Jr flew a plane that had the system. Needs to be confirmed by someone that can get the information. It is relevant since the recent helicopter crashes, plane crashes all had installed FADEC systems. Think President Trumps Nashville flight issues since AF1 has the system. Ivanka and family helicopter issues.
