What should the pressure of the hydraulic accumulator be?

The correct pressure for the hydraulic accumulator is 900 +/- 50 PSI. This specific pressure range is critical for the proper operation of the hydraulic system, ensuring it can effectively store energy and release it when needed. The functionality of the hydraulic accumulator is influenced by its pressure, which must be maintained within designated limits to prevent system failures or inefficiencies. Having the accumulator at 900 PSI enables it to provide reliable hydraulic power, effectively accommodate fluctuations in system demands, and contribute to overall system stability and performance.

In contrast, the other options present ranges that are not appropriate as they fall outside the established parameters necessary for optimal hydraulic system performance. As such, maintaining the accumulator at 900 PSI is vital for safe and efficient aircraft operation.
