Disclosed is a method of controlling an internal combustion engine (102) of a UAV (100), and also disclosed is a UAV engine system (101), The engine (102) has a fuel delivery means (123) operable to deliver a fuel to a combustion chamber of the engine, and an air flow control means (107) for regulating air flow to the combustion chamber. The method comprises controlling the engine (102) through control of fuelling by way of the fuel delivery means (123) independently of the air flow control means (107), including determining a fuelling requirement for the engine based on a request from a flight control system, and determining an air flow requirement based on or with reference to the fuelling requirement. This provides for fuel-led control of the engine system (101). Specifically, a fuelling requirement for the engine (102) is determined and implemented, and the corresponding air requirement is then determined contingent upon the fuelling requirement.
