A taxi guidance system is provided for an aircraft having a primary thrust engine and an onboard electric taxi system. The taxi guidance system includes or cooperates with a source of aircraft status data for the aircraft, and a source of airport feature data associated with synthetic graphical representations of an airport field. The taxi guidance system includes a processor operatively coupled to the source of aircraft status data and to the source of airport feature data to generate, in response to at least the aircraft status data and the airport feature data, taxi path guidance information for the aircraft, start/stop guidance information associated with operation of the primary thrust engine, and speed guidance information for the onboard electric taxi system. The processor generates image rendering display commands that can be received by a display system to render a dynamic synthetic representation of the airport field that includes graphical indicia of the taxi path guidance information, the start/stop guidance information, and the speed guidance information.
