Engineers at Solar Impulse used Polyspace^®static analysis to ensure the software in their solar plane complied with DO 178B. Polyspace products helped save 1 to 2 man-years in development, and they helped researchers find and eliminate problems earlier and faster in order to meet objectives. Solar Impulse is the only airplane of perpetual endurance able to fly day and night on solar power without a drop of fuel. The challenge is to attempt the first round-the-world solar flight in 2015—and it is a way for the team to demonstrate how a pioneering spirit, innovation, and clean technologies can change the world.
