The engine driven hydraulic pump pressurizes the hydraulic system to which of the following?

Explanation:
Engine-driven hydraulic pumps in aircraft are designed to develop high pressure to power flight controls, landing gear, and other actuators. The system is built to operate at about 3,000 psi, with a tolerance of roughly ±120 psi. This provides enough force to move heavy components reliably while staying within the system’s safety limits. A pressure around 1,800 psi would generally be too low to actuate the required components effectively, and a looser tolerance (±150 psi) could lead to performance variations under different temperatures and wear. The designated range around 3,000 psi with a ±120 psi tolerance matches how the hydraulic system is specified to perform.
