Which item is the third check in the AFFF 'manned and ready' readiness procedure?

• A. X50J AFFF phone circuit is manned
• B. Power Availability Lights illuminated
• C. Fuel level indicator
• D. Interior temperature

Answer: (B)

In the manned and ready readiness sequence, confirming that electrical power is available is essential before proceeding with other checks. The third check is to verify that the Power Availability Lights are illuminated, which signals that power is present to the AFFF system and its controls. This ensures the system can be activated, alarms will function, and you can perform the remaining readiness steps safely. The other items — ensuring the AFFF phone circuit is manned, checking fuel level, and noting interior temperature — are important aspects of readiness, but they do not confirm that power is available, which is why the power lights being on is the correct third check.
