Abstract
A lubrication circuit for a gas turbine engine comprises a heat exchanger having an inlet pipe which carries a flow of lubricant to the heat exchanger; a heater configured to heat lubricant to produce a flow of heated lubricant to be provided to the heat exchanger; and a sensor operable to measure a measured parameter from which it can be determined whether the lubricant requires heating.
