electric aviationUsing electric motors to power airplane propeller engines to lessen pollution in the atmosphere. Electric aviation also means fewer hours of scheduled maintenance because gasoline motors need to be overhauled 10 times more frequently than electric (every 2,000 hours versus 20,000). However, batteries are heavy, and the first electric planes are expected for small commuter flights. In 2019, Eviation Aircraft had a backorder for more than 150 of its nine-passenger Alice airplanes with a range of 650 miles. As of 2020, there were more than 100 electric aviation projects under development worldwide. See electric vehicle.
