Patent ID: 8025503

Claim:
A method of providing for simulation of a one-engine-inoperative (OEI) condition in a multi-engine helicopter, the method comprising the steps of providing a OEI training program in a control system such that the control system is adapted to control the engines in an engine normal operation mode and in an OEI training mode; and providing a selector for selection of the OEI training mode to allow the control system to control a plurality of engines in accordance with the following steps: reducing a power level of all of the engines from a respective normal operational power level to a non-zero power level below the respective normal operational power level, the normal operational power level of an engine being the power level set prior to entering the OEI training mode; and then increasing the power level of each of the engines from their respective non-zero power level to a respective power level higher than the respective non-zero power level, the increasing returning each engine, substantially to its respective normal operational power level after the step of increasing and while still in the OEI training mode, and wherein the power levels of the engine are thereby substantially equal to one another.
