An aircraft propulsion system includes a hybrid-electric power plant for delivering power to an air mover for propelling an aircraft. The hybrid-electric power plant includes a heat engine operatively connected to a first air mover, and an electric motor operatively connected to a second air mover. The second air mover is positioned on a wing of the aircraft outboard from the heat engine. A method for reducing trailing vortices includes powering a first air mover of an aircraft with a heat engine during a take-off stage, a climb stage, a cruise-stage and/or a descent stage. The method includes powering a second air mover of the aircraft with an electrical motor during the take-off stage and/or the climb stage. The method includes freewheeling the second air mover during the cruise stage and/or the descent stage to generate mechanical energy and reduce wing tip vortices.
