What is Standard Note 1?

• A. Loss of Power
• B. Loss of System
• C. Loss of Water
• D. Loss of Air

Answer: (A)

Standard Note 1 is about Loss of Power. In CSOSS, Standard Notes are concise, pre-approved casualty statements that guide the immediate actions you take when a specific condition occurs. Loss of power is the fundamental casualty because power supports virtually all shipboard systems—sensors, weapons, communications, and consoles rely on it. Recognizing this condition with the standard note prompts you to follow the established, rapid actions to identify the power loss, protect critical equipment, restore essential power, and coordinate with the engineering team for recovery. The other conditions listed would be handled under their own standard notes, so Loss of Power is the best fit for Standard Note 1.
