System and method for conducting one engine inoperative flight

Abstract

A system and method for conducting one engine inoperative (OEI) flight procedures training in a dual-engine helicopter includes a multi-function OEI training switch that is operative to initiate OEI flight procedures training by selecting one of said engines as the single operative engine for OEI flight procedures training, and a training function module that is: (1) operative to establish suppressed 30-second, 2-minute, and maximum continuous OEI operating limits for selected engine operating parameters to limit the actual power provided by said powerplant system during OEI flight procedures training; and (2) operative to generate biasing factors to control the operation of the parametric indicators for the selected engine operating parameters during OEI flight procedures training. During OEI flight procedures training, the training function module limits the actual power output of the helicopter powerplant system to the suppressed 30-second, 2-minute, or maximum continuous OEI operating limits, as selected by the pilot, while simultaneously utilizing the biasing factors to cause the parametric indicators of the selected operative engine to provide display indications to the pilot that the selected operative engine is operating at the actual 30-second, 2-minute, or maximum continuous OEI operating limits, as applicable.
