The take-off hydraulic pressure controlled by LP is in what range?

• A. 250-260
• B. 300-310
• C. 320-330
• D. 290-300

Answer: (B)

The main idea here is that the LP (low-pressure) hydraulic system is tuned to hold take-off pressure in a narrow, specific window to ensure the flight controls move reliably during takeoff. The LP-controlled take-off pressure is maintained around 300–310 psi, which provides enough actuator force for rapid and precise control surface movement without pushing the system beyond its design limits. Pressures lower than this window could result in sluggish or insufficient control response, while pressures higher than this window could risk overloading components or causing leaks. Among the given ranges, 300–310 psi is the only one that matches the intended take-off pressure window, making it the correct choice.
