What is the normal pressure range for the nitrogen system?

The normal pressure range for the nitrogen system, which is crucial for various aircraft systems including hydraulic systems, is indeed 1350-1650 PSI. This range ensures that the nitrogen can effectively act as a pressurizing medium, maintaining proper system functionality and efficiency.

In many aircraft, nitrogen is used in systems that require a stable, non-flammable gas that can withstand high pressures. The specified range allows for safe operation while accommodating the pressures needed for system activation and performance. When the pressure falls below or exceeds this range, it can lead to inadequate system performance or potential failure, impacting safety and operational effectiveness.

The other ranges provided do not align with the established standards for nitrogen system pressures, as they either fall short or exceed the necessary operational threshold for ensuring safety and functionality in aviation systems. Thus, the selection of 1350-1650 PSI is backed by standardized practices in aircraft engineering and maintenance.
