Classification: CPC F | IPC F

Claim 16:
17. A system for a gas turbine engine, comprising:
a lubricant system with a lubricant reservoir;
a sensor system configured to monitor lubricant within the lubricant reservoir; and
a monitoring system configured to
determine a first lubricant parameter based on first sensor data received from the sensor system while the gas turbine engine is operating during a first period of an operating cycle of the gas turbine engine, the first lubricant parameter indicative of a first quantity of lubricant within the lubricant reservoir;
determine a second lubricant parameter based on second sensor data received from the sensor system while the gas turbine engine is operating during a second period of the operating cycle of the gas turbine engine, the second lubricant parameter indicative of a second quantity of lubricant within the lubricant reservoir; and
determine a lubricant consumption parameter based on the first lubricant parameter and the second lubricant parameter, the lubricant consumption parameter indicative of a quantity of the lubricant consumed by the gas turbine engine during the operating cycle.
