A method of automatically regulating a power plant (') of an aircraft (), said power plant comprising at least one turbine engine (), said aircraft () having at least one rotary wing () provided with a plurality of blades () having variable pitch and driven in rotation by said power plant (′), it being possible for each engine () to operate in an idling mode of operation and in a flight mode of operation. During a selection step (STP), a two-position selector () is operated either to stop each engine () or to set each engine () into operation. During a regulation step (STP), each engine () is controlled automatically so as to implement the idling mode of operation if the collective pitch (CLP) of said blades is less than a threshold and if the aircraft () is standing on the ground.
