A power management symbology (PMS) display system for helicopters that provides a continually updated, combined analog/digital symbolic display of selected status information vis-a-vis the helicopter powerplant. The PMS display system includes a multi-dimensional, continuously updated, combined analog/digital display symbol that is optimized for discriminability and compatibility with respect to the pilot's visual system. The power management symbol includes a first dimension that is a static, analog representation of 120 percent nominal torque rating of the helicopter powerplant that functions as a referent, a second dimension that is a dynamic, analog representation of the maximum continuous power available from the powerplant, a third dimension that is a dynamic, analog representation of the power required to hover OGE, a fourth dimension that is a dynamic, digital/analog representation of the average instantaneous power being provided by the powerplant, and a fifth dimension that is an analog representation of a "torque split" condition of the powerplant that is only visible when the individual power outputs between the engines of the powerplant exceed a predetermined threshold differential. The PMS display system further includes a computer means, first and second sensor subsystems, a video display subsystem, and a sensing subsystem which, in combination, generate a synchronized video image of the power management symbol for the video display subsystem.
