Where are the crew alerting system (CAS) messages displayed when a master warning occurs?

Explanation:
When a master warning occurs, the CAS messages are shown on the EICAS display. The EICAS is designed to centralize engine parameters and crew alerting messages, so all urgent system alerts appear there in a dedicated area, making it easy to identify what’s triggering the warning. The PFD mainly shows flight data and may hint at warnings visually, but it doesn’t present the full CAS list. The NAV display focuses on navigation information, not system alerts. The engine instrument panel shows engine parameters, not the centralized alert messages.
