A method of operating an aircraft hybrid gas turbofan during an idle mode of operation includes reducing a fuel flow to a primary gas turbine engine (12) and boosting a high spool (18) of the primary gas turbine engine (12) using a secondary gas turbine engine (14) via a first power linkage connecting the primary and secondary gas turbine engines (12, 14), such that a net fuel reduction is achieved. The net fuel reduction accounts for fuel flow to the primary gas turbine engine (12) and fuel flow to the secondary gas turbine engine (14).
