First Hybrid-Electric Plane Flies For Ampaire Ampaire has flown its first hybrid-electric plane. The aircraft utilized is a Cessna Grand Caravan that has been modified with Ampaire's integrated propulsion system of a compression ignition engine and an electric engine. They call it the Eco Caravan. At present it is a hybrid aircraft and eventually the company may endeavour to fully electrify the aircraft. However, it isn't very easy to decarbonize aviation and with current battery tech limiting range, sometimes hybrid is the best methodology to use.
