What function does the engine data manager (EDM) NOT monitor?

The engine data manager (EDM) is designed to monitor and manage various parameters related to engine performance for optimal efficiency and safety. It tracks important metrics such as engine torque, fuel flow, and cockpit pressure altitude to ensure that the engine operates within its prescribed limits.

Fuel combustion, while critical to engine operation, is not a parameter that the EDM directly monitors. Instead, the EDM focuses on quantifiable metrics that reflect the operational status of the engine. Monitoring fuel combustion would typically involve more complex analysis related to combustion efficiency and emissions, which goes beyond what is routinely measured by the EDM. Thus, the option of fuel combustion is accurately identified as the function that the EDM does not monitor.
