- Contexto
- Modern engines are electronically controlled through a dedicated computer, known with different names, including Full Authority Digital Engine Control (FADEC), Electronic Engine Control (EEC) or Engine Control Unit (ECU). This system is not hardened against crash damage and it is not intended to provide accurate data in case of an accident, but in the absence of FDR information, any data retrieved from the engine FADEC may be helpful in providing some information about the last minutes of flight. However, the FADEC memory is designed for engine maintenance troubleshooting purposes and the “time stamp” indicating when faults occurred versus when they were written to memory is of poor resolution for accident investigation purposes.
