<p><P>PROBLEM TO BE SOLVED: To provide a method for avoiding an increase in time and cost for improving the hydraulic devices of an aircraft and for designing and receiving accreditation of the improved hydraulic system. <P>SOLUTION: This aircraft 1 includes at least one in-flight attitude control system 4, 5, having at least one actuator 6; 7; and a hydraulic circuit connected to the actuator 6; 7 and having at least one pump 8. The hydraulic circuit is designed to deliver a first flow when the pressure of the hydraulic circuit exceeds a presettable threshold value. The pump 8 is designed to deliver a second flow greater than the first flow. The aircraft 1 includes a sensor 11a, 11b, 12, 13 for detecting a value associated with the pressure of the hydraulic circuit; and a programmable central control unit 10 which controls the pump 8 to deliver the second flow when the value detected by the sensor 11a, 11b, 12, 13 corresponds to the pressure of the hydraulic circuit below the threshold value. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
