All of the functions performed by the engine data manager (EDM) are engine related.

The statement that all of the functions performed by the engine data manager (EDM) are engine related is false. While a significant portion of the EDM's functions pertains directly to engine performance and monitoring—such as tracking parameters like RPM, fuel flow, and temperature—it also encompasses other essential functions that extend beyond just engine data. The EDM integrates information from various systems, including fuel management, and provides critical alerts and information related to operational status, thereby enhancing overall aircraft performance. Therefore, it engages with other subsystems which may not be strictly classified as engine related, highlighting the multifunctional capabilities of the EDM within the aircraft.
