Final answer:
The "Engine Oil" aural warning and EICAS message ENG OIL PRESS signals an issue with the engine oil pressure in an aircraft, requiring immediate action by the flight crew to prevent engine damage.
Step-by-step explanation:
The message "Engine Oil" along with the EICAS (Engine Indicating and Crew Alerting System) message ENG OIL PRESS indicates that there is an issue with the engine oil pressure in an aircraft. This is a significant warning that requires immediate attention from the flight crew. Low engine oil pressure can lead to insufficient lubrication of engine components, which in turn can cause engine damage or failure. The standard procedure that crews should follow upon such a warning includes checking the engine oil pressure indications, confirming the operating parameters, and potentially shutting down the affected engine if necessary, following the checklist procedures provided by the Aircraft Flight Manual (AFM).
