What is the required hydraulic pressure to power the landing gear and other systems?

The required hydraulic pressure to effectively power the landing gear and other systems is specified as above 1,800 psi. This indicates that the hydraulic systems in many aircraft, especially in modern designs, require a robust and reliable pressure to ensure the proper functioning of critical components such as the landing gear, brakes, and other hydraulic systems.

Operating above 1,800 psi provides adequate force to engage and disengage landing gear smoothly and efficiently, maintaining safety and operational reliability. Higher pressures can facilitate the quick actuation of hydraulic systems, which is vital for performance during critical phases of flight, such as takeoff and landing. Adopting a pressure threshold above this level ensures that there is enough power to handle potential loads and rapid movements, which are crucial for the safe operation of these systems.

In contrast, lower pressures, whether set at 1,200 psi or 1,800 psi, may not provide the necessary performance and responsiveness required for such critical systems in high-performance aircraft, potentially leading to malfunction or slower response times during essential operations.
