Hydraulic Functionality: A hydraulic landing gear retraction system utilizes pressurized hydraulic fluid to actuate linkages to raise and lower the gear When the switch is moved to the UP position, hydraulic fluid is directed into the gear-up line The fluid flows through sequenced valves and down-locks to the gear-actuating cylinders A similar process occurs during gear extension The pump that pressurizes the fluid in the system can be either engine-driven or electrically-powered If using an electrically powered pump to pressurize the fluid, the system is called an electro-hydraulic system The system also incorporates a hydraulic reservoir to contain excess fluid and to provide a means of determining the system fluid level Regardless of its power source, the hydraulic pump operates within a specific range When a sensor detects excessive pressure, a relief valve within the pump opens, and hydraulic pressure routes back to the reservoir Another type of relief valve prevents excessive pressure that may result from thermal expansion Limit switches also regulate hydraulic pressure Each gear has two limit switches-one dedicated to extension and one dedicated to retraction These switches de-energize the hydraulic pump after the landing gear has completed its gear cycle In the event of a limit switch failure, a backup pressure relief valve activates to relieve excess system pressure
