The Solar Impulse team is preparing to tackle one of solar power’s biggest challenges: night.
The team has a goal of flying around the globe without using a drop of fossil fuel. That means the solar panels on the aircraft must gather and store enough energy during the day to propel the aircraft through the night.
The Solar Impulse prototype, which has a 208-foot wingspan and weighs a little more than 3,500 pounds, made its first flight April 7. Propelled by four 10-hp electric engines, it gathers energy from solar cells on the wings and horizontal stabilizer and flies at an average speed of 38 knots.
Early this month, the prototype flew for four hours and 50 minutes, its longest flight thus far. The team reported that this was the aircraft’s first energy-positive flight. “This means, as Claude Nicollier stated, that ‘we came back with significant more energy than we took off with,’” wrote Martin Reichlin in a blog.
A state-of-the art medical facility on remote Tangier Island in the Chesapeake Bay serves as a lasting memorial to the late Dr. David B. Nichols’ dedication to providing medical care to the community for 30 years. Now, Nichols’ aviation legacy—flying a Cessna 182 or Robinson R44 to the island every Thursday to provide that care—is set in stone.
Daher-Socata announced that it had installed the first Garmin G600 and GTN 750 avionics in one of its 2004 TBM 700C2 airplanes.
Even brief flight under actual conditions can expose how well your basic instrument flying is serving.
