A method of controlling load share between a plurality of engines, comprising: ascertaining a load share participation value indicative of a load share participation regime for a first engine, the load share participation value depending at least in part on one or more operating conditions of a second engine and being indicative of one of: a full-participation load share regime, whereby the first engine may fully participate in load sharing by either increasing torque and/or thrust or decreasing torque and/or thrust so as to more closely match the torque and/ or thrust of one or more of the other engines; a partial-participation load share regime, whereby the first engine may partially participate in load sharing, but a nature or extent to which the first engine may participate in the load sharing is limited relative to the full-participation load share regime; and a non-participation load share regime, whereby a load sharing requirement control command for the first engine may cause a change in the torque or thrust of the first engine, but a decrease in fuel flow to the first engine is prevented or not caused for purposes of load sharing; and outputting a load sharing requirement control command for the first engine configured to change a torque or thrust output of the first engine for purposes of load sharing when the load share participation value indicates a full-participation load share regime or a partial-participation load share regime for the first engine; characterized by outputting a load sharing requirement control command for the first engine that may cause a change in the torque or thrust of the first engine, but either prevents or does not cause a decrease in fuel flow to the first engine for purposes of load sharing, when the load share participation value indicates a non-participation load share regime for the first engine. ascertaining a load share participation value indicative of a load share participation regime for a first engine, the load share participation value depending at least in part on one or more operating conditions of a second engine and being indicative of one of: a full-participation load share regime, whereby the first engine may fully participate in load sharing by either increasing torque and/or thrust or decreasing torque and/or thrust so as to more closely match the torque and/ or thrust of one or more of the other engines; a partial-participation load share regime, whereby the first engine may partially participate in load sharing, but a nature or extent to which the first engine may participate in the load sharing is limited relative to the full-participation load share regime; and a non-participation load share regime, whereby a load sharing requirement control command for the first engine may cause a change in the torque or thrust of the first engine, but a decrease in fuel flow to the first engine is prevented or not caused for purposes of load sharing; and a full-participation load share regime, whereby the first engine may fully participate in load sharing by either increasing torque and/or thrust or decreasing torque and/or thrust so as to more closely match the torque and/ or thrust of one or more of the other engines; a partial-participation load share regime, whereby the first engine may partially participate in load sharing, but a nature or extent to which the first engine may participate in the load sharing is limited relative to the full-participation load share regime; and a non-participation load share regime, whereby a load sharing requirement control command for the first engine may cause a change in the torque or thrust of the first engine, but a decrease in fuel flow to the first engine is prevented or not caused for purposes of load sharing; and outputting a load sharing requirement control command for the first engine configured to change a torque or thrust output of the first engine for purposes of load sharing when the load share participation value indicates a full-participation load share regime or a partial-participation load share regime for the first engine; characterized by outputting a load sharing requirement control command for the first engine that may cause a change in the torque or thrust of the first engine, but either prevents or does not cause a decrease in fuel flow to the first engine for purposes of load sharing, when the load share participation value indicates a non-participation load share regime for the first engine.
