Methods of monitoring hydraulic fluid levels in an aircraft

摘要

A method 100 of monitoring hydraulic fluid levels in an aircraft includes identifying segments of operation where the aircraft meets predetermined stability criteria 102 and receiving output from a fluid sensor 104. Hydraulic fluid levels within the at least one hydraulic storage tank 106 are then calculated. A hydraulic fluid value indicative of the amount of hydraulic fluid in the aircraft is determined based on at least the calculated hydraulic fluid level 108. An indication of the hydraulic fluid value 110 is then provided.
