## GM1 Article 2(8c) Definitions

MEANING OF THE TERM ‘SINGLE THRUST CONTROL’

The [SEP aeroplane](https://avioverse.aero/glossary/easa/sep-aeroplane) class, as defined in Article 2(8c), includes aeroplanes whose single propulsion unit (propeller) is driven by more than one engine (e.g. a hybrid engine system, consisting of a piston and an electric engine). Despite such a ‘multi-engine’ power plant system, such an [aircraft](https://avioverse.aero/glossary/easa/aircraft) can follow the single-engine [aeroplane](https://avioverse.aero/glossary/easa/aeroplane) licensing framework since malfunctions of one engine will lead to a (partial) loss of power but never to an asymmetric flight condition. Hence, if during the certification process for a particular aeroplane it is determined that, from a pilot’s perspective, there is no difference between operating a conventional single-engine power plant and the as above described multi-engine single-propeller power plant of the aeroplane under certification, that aeroplane for the purpose of flight crew licensing can be treated as a single-engine aeroplane. In this context, the term ‘single thrust control’ is meant to refer to engine controls of such an innovative power plant which are equivalent to the engine controls of a conventional single-engine power plant.
