In Zunum's plane, battery packs are located in each wing and will be relied upon first to power the aircraft. The plane's rear fuselage can be used to store either a third battery pack — to make the plane fully electric — or in the case of JetSuite, a range extender consisting of a traditional gas turbine coupled with a generator that creates electricity to power the plane's electric motors, said Ashish Kumar, chief executive of Zunum.
