A gas turbine engine includes a gearbox assembly that includes a gearbox and a gutter for collecting a gearbox lubricant scavenge flow from the gearbox. The gutter is characterized by a lubricant extraction volume ratio between 0.01 and 0.3, inclusive of the endpoints. The lubricant extraction volume ratio defined by:VGVG⁢B.VG is a gutter volume of the gutter and VGB is a gearbox volume. The gas turbine engine includes a lubricant flow control system that includes a variable flow lubricant pump that generates a pump variable flow of lubricant to the gearbox assembly. The gearbox assembly has a variable consumption demand for delivery of lubricant. A lubricant flow controller is configured to generate a pump control command for the variable flow lubricant pump to produce the pump variable flow of lubricant based on the variable consumption demand.

The present disclosure relates to a lubrication monitoring system (15) configured to monitor a supply of lubricant in a hand-held cutting tool (1) having a cutting unit (3, 5). A lubricant tank (41) and a conduit (45) are configured to duct a flow of lubricant from the tank (41) to the cutting unit (3, 5). The lubrication monitoring system (15) comprises a heating element (29) and a sensor arrangement (31, 33), the heating element (29) being configured to heat the lubricant flow. The sensor arrangement comprises a first sensor (31) located at the flow, upstream of the heating element (29), and a second sensor (33) located at said flow, downstream of the heating element. The lubrication monitoring system outputs a monitoring signal based on a sensed temperature difference between the first and second sensors (31, 33).
