What is the normal operating pressure of the hydraulic systems?

The normal operating pressure of the hydraulic systems in the Canadair Regional Jet is indeed 3000 psi, with a tolerance of plus or minus 200 psi. This pressure is critical for the effective operation of various flight systems, such as flight control surfaces, landing gear, and braking systems. Maintaining this pressure within the specified range is essential to ensure the proper functionality and responsiveness of these systems, which are vital for safe flight operations.

Understanding hydraulic systems' operating pressures helps ensure that pilots and maintenance personnel can diagnose and address any anomalies effectively. If pressures fall outside this range, it could lead to reduced performance or failure of the hydraulic components linked to flight safety, highlighting the importance of regular checks and maintenance.
