What is the maximum fueling pressure allowed?

The correct answer is based on the guidelines established for the fueling procedures of the MH-60S. The maximum fueling pressure allowed is 55 PSI. This specification is essential for ensuring that the fuel is delivered safely and effectively into the aircraft's tanks without causing damage or compromising the integrity of the fueling system.

Maintaining pressures within this limit helps prevent fuel spills and mitigates the risk of vapor release, which can lead to hazardous situations. Operating beyond this pressure could result in adverse effects such as fuel leakage or stress on the fueling equipment, which is engineered to operate within specific tolerances.

This standard ensures not only the safety of the aircraft during fueling operations but also protects ground personnel and equipment, making it critical for all personnel involved in fueling operations to adhere strictly to these pressure limits.
