The method comprises receiving a gaseous fuel flow request indicative of a change in demand for gaseous fuel to the engine; applying a fuel loss bias to the gaseous fuel flow request to obtain a biased fuel flow request, the fuel loss bias associated with a change in mass flow rate of the gaseous fuel from the fuel manifold (200) to the combustor (16) in response to the change in demand; and causing the gaseous fuel to flow into the combustor (16) in accordance with the biased fuel flow request.",
