Which unit is responsible for collecting information to be displayed on the EICAS?

• A. Data Collector Unit - Collects information for showing on the EICAS
• B. Lamp Display Unit - Illuminates various lamps around the cockpit
• C. Data Communications Unit - Handles ACARS messages
• D. Display Control Unit - Manages primary screens

Answer: (A)

Data Collector Unit is responsible for gathering information from sensors across engines and other aircraft systems, then feeding that data to the EICAS so the engine parameters and crew alerts can be displayed accurately. This data flow is what makes the numbers and messages on the EICAS meaningful. The Lamp Display Unit handles cockpit lamp illumination, the Data Communications Unit deals with ACARS messages, and the Display Control Unit manages how information appears on the screens—relying on the DCU to provide the actual data.
