Ampaire’s Electric EEL Skymaster Makes Longest Flight Yet Electric propulsion systems developer Ampaire last week achieved its longest flight with the Cessna 337 Skymaster that it has converted to hybrid-electric power. On Thursday, the six-seat, Electric EEL aircraft took off from the Los Angeles-area Camarillo Airport and made a 341-mile flight to Hayward Executive Airport in the San Francisco area in 2 hours and 35 minutes. Ampaire, claims this was the longest flight to date for what it defines as a “commercially relevant” aircraft using electric propulsion.  The Electric EEL is powered by a 310-hp Continental IO-550 engine installed in the tail of the aircraft and a 130-kW electric motor in the nose. According to Ampaire, the piston engine powered all taxiing, and then a combination of it and the electric motor were used for takeoff and climb. The cruise phase was mainly powered by the piston, while the motor was put in low power mode, before being switched to idle during descent and landing.  Piloted by test pilot Justin Gillen and flight-test engineer Russell Newman, the flight averaged 135 mph as it traversed California’s Central Valley at an altitude of 8,500 feet. “The mission was a quite normal cross-country flight that we could imagine electrified aircraft making every day just a few years from now,” said Gillen.
