Abstract

The Green Flight Challenge occurred in September 2011 as a competition to spur extreme flight efficiency for general aviation aircraft. In order tocompete, an aircraft hadto demonstrate flight over a 200 mile course at an average groundspeed of 100 mph with a fuel efficiency greater than 200 passenger miles per equivalent gallon. This paper describes the design of Taurus G4, the world's first four-seat electric-powered aircraft, and the flight-planning techniques used in winning the competition. The aircraft demonstrated flight over a 196 mile course at an average speed of 107mphand an average equivalent fuel efficiency of 403.5 passenger miles per equivalent gallon of automotive gasoline. In this demonstration, it showed that battery-powered flight is practical for general aviation missions.
