Abstract
A method is provided for determining a gas charge pressure Pof a hydraulic accumulator within a hydraulic fluid system. The method includes receiving pressure decay data representing the pressure decay within a self-pressurizing hydraulic reservoir of the hydraulic fluid system as the self-pressurizing hydraulic reservoir depressurizes from an operating pressure of the self-pressurizing hydraulic reservoir towards atmospheric pressure. The method also includes calculating the gas charge pressure Pof the hydraulic accumulator using the received pressure decay data of the self-pressurizing hydraulic reservoir.
