ABSTRACT:
The minimum fuel flow to a combustor of a gas turbine engine is controlled in response to the combustor inlet temperature T3in order to provide a FAR stability margin which responds to the combustor inlet temperature. This enables the FAR stability margin to be reduced when the risk of flame out is low, for example when the combustor entry temperature is high, while increasing the FAR stability ratio when the combustor entry temperature is low, ie when the engine is idling or when water is ingested.
