The EDM passes oil pressure data to which computer that contains the logic to illuminate CWS annunciators?

The correct answer is the Signal Conditioning Unit (SCU). This unit is responsible for processing and conditioning sensor data, including oil pressure readings, before passing this information to the systems that control various alerts, such as the Caution and Warning System (CWS). The SCU takes in signals from various sensors, conditions them for accuracy and reliability, and then transmits that information to other computers or systems within the aircraft.

In the context of oil pressure, the SCU processes this critical data and ensures that any anomalies can trigger the appropriate warnings, contributing to overall flight safety. Understanding the role of the SCU is vital for comprehending how mechanical data is integrated and communicated within the aircraft's systems, making it a fundamental component in warning and monitoring processes.
