The engine data manager performs all the following, EXCEPT _______________.

The engine data manager plays a critical role in the operation and monitoring of engine performance in the T-6B. It is specifically designed to handle engine-related functions, which include monitoring various operating parameters, processing these parameters to ensure optimal performance, and driving the engine instrument displays to provide real-time information to the pilot.

It also provides discrete alerts to the Integrated Avionics Computer (IAC) for any irregularities or necessary adjustments in engine performance. This function is essential for safety and operational efficiency, as it ensures that the pilot is informed of any issues that may arise during flight.

The option concerning monitoring and processing Angle of Attack (AOA) data falls outside the scope of the engine data manager's responsibilities. AOA data is typically managed by other systems designed to monitor flight dynamics and ensure the aircraft maintains safe operating limits during maneuvers. Therefore, the engine data manager does not handle AOA-related functions, making it the correct answer in this context.
