What indication is displayed on the EICAS when the cargo door is not fully closed and locked on the ground?

The indication displayed on the Engine Indication and Crew Alerting System (EICAS) when the cargo door is not fully closed and locked while on the ground is an amber cargo door caution. This caution alert informs the crew that there is a potential issue that requires attention, specifically regarding the status of the cargo door. The amber color signifies that the situation is not an emergency but is something that should be monitored and addressed before proceeding with flight operations.

In contrast, a red warning would typically indicate a more critical failure requiring immediate action, while a green indication would mean that the cargo door is in a normal operational state. The absence of any indication would imply that the cargo door is securely closed and locked, which is not the case in this scenario. Therefore, the amber caution serves as an important reminder for the crew to ensure that all cargo doors are operationally safe before takeoff.
