What is the maximum fuel pressure allowed during fueling operations?

The maximum fuel pressure allowed during fueling operations for the Super Hornet is 55 PSI. This pressure level is essential to ensure the safe and efficient transfer of fuel into the aircraft's tanks without causing damage to the fueling system or the aircraft itself. Maintaining the proper fuel pressure is crucial to prevent issues such as fuel spills, which can arise from excessive pressure. These operational parameters are established in safety regulations and manufacturer guidelines to ensure that all fueling operations are conducted within safe limits, thus minimizing risks associated with fueling handling and aircraft operation.

The other options exceed the recommended maximum, which would pose safety risks during fueling operations, making 55 PSI the key value to adhere to in order to operate within safe and effective parameters.
