Abstract

A gas turbine engine for an aircraft. The gas turbine comprises a staged combustion system having pilot injectors (305) and main injectors (306), a fuel metering system (211) configured to control fuel flow to the pilot injectors and the main injectors, and a fuel system controller (212). The controller is configured to identify an atmospheric condition, determine a ratio of pilot fuel flow rate for the pilot injectors to main fuel flow rate for the main injectors in response to the atmospheric condition, and inject fuel by the pilot injectors and the main injectors in accordance with said ratio to control an index of soot emissions caused by combustion of fuel therein.
