What is the maximum defuel pressure?

• A. -1 psi
• B. -3 psi
• C. 0 psi
• D. -5 psi

Answer: (B)

The maximum defuel pressure for the MH-60S is -3 psi. This pressure indicates the maximum negative pressure that can be safely applied during the defueling process. Proper defuel pressure management is crucial to ensure the safe transfer of fuel from the aircraft to the storage system without causing damage to the fuel system or creating hazardous conditions. A negative pressure is utilized to aid in the removal of fuel, and adhering to the specified limit is essential for operational safety. Knowing the correct maximum defuel pressure is an important aspect of fuel management tasks for the plane captain, as it helps in preventing potential fuel spills, contamination, or system failures that could arise from exceeding these limits.
