Abstract
An indication system for a hybrid aircraft power plant including an electric motor and a heat engine for driving an air mover configured to propel an aircraft is provided. The indication system includes a display providing a display area and a computer operatively connected to the display. The computer is configured to cause a first visual indication to be generated in the display area of the display. The first visual indication indicates a current amount of energy stored in a battery powering the electric motor of the hybrid aircraft power plant along a scale. The computer is configured to cause a second visual indication to be generated in the same display area of the display. The second visual indication indicates a remaining run time for the electric motor based on the current amount of energy stored in the battery.
