Difficulty: MediumQuantitative Detail Extraction

During scheduled maintenance on the airfield Mobile Aircraft Arresting System (MAAS), technicians inspect the energy absorber brakes. The primary hydraulic retractor operates at an operating pressure of 1,850 PSI, while the brake accumulator must be pre-charged with dry nitrogen to 450 PSI. During routine proof-testing, the maximum allowable surge pressure is 2,200 PSI, and complete fluid replacement is mandated every 36 months.

According to the passage, what is the required dry nitrogen pre-charge pressure, in PSI, for the brake accumulator?

Answer: 450 PSI

Answer

450 PSI
The passage explicitly states that 'the brake accumulator must be pre-charged with dry nitrogen to 450 PSI.' Thus, 450 is the exact required value.

Step-by-Step Solution

1
Scan the passage to locate the specific component and parameter in question.
Located the phrase: 'the brake accumulator must be pre-charged with dry nitrogen to 450 PSI.'
Isolating the target component ensures that the quantity extracted is not confused with adjacent technical specifications.
2
Extract the exact numerical figure associated with the accumulator pre-charge.
450 PSI
The passage directly links 450 PSI to the dry nitrogen pre-charge requirement for the accumulator.
