The engine data manager (EDM) also performs non-engine related functions such as ______________.

The engine data manager (EDM) serves various critical roles within the aircraft systems, extending beyond just engine management. It monitors and processes data related to the engine, but it also plays a vital part in managing broader aircraft systems.

The role of the EDM in fuel balancing and fuel quantity indications is essential as it ensures proper distribution of fuel across the tanks, which is crucial for maintaining balance and performance. This affects the aircraft's center of gravity, which is vital for safe handling and stability during flight.

Additionally, the EDM's capability to determine and display DC volts and amps is important for managing the electrical systems of the aircraft. This information is critical for monitoring battery performance and ensuring that the electrical system is within operational specifications.

Furthermore, the EDM provides cockpit pressure altitude and differential pressure readings. This information is important for the overall situational awareness of the crew, particularly during ascent and descent phases of flight, as it directly impacts aircraft performance and safety.

Therefore, the correct answer signifies that the EDM integrates multiple functionalities, including fuel management, electrical monitoring, and pressure data, indicating its comprehensive role in the aircraft's systems. Each of these functions contributes to the overall safety and efficiency of the aircraft operation.
