Abu Dhabi:  The first solar plane attempting  round-the-world flight  has taken off from  Chongqing towards Nanjing  in China on Tuesday morning after waiting for three-weeks due to bad weather.

Bertrand Piccard is flying the plane for an expected 14 hours across China in its sixth leg. Since the plane landed in Chongqing on March 31, cloudy weather conditions and excessive crosswinds prevented its  take-off.

Solar Impulse meteorologists and simulation teams were battling with unfavourable weather conditions  to find solutions for plane’s departure from Chongqing.  Strategies explored included alternative routes, possible pit stops and flying at various altitudes. While considering several possibilities, the Civil Aviation Authority of China (CAAC) was very supportive, collaborative and flexible, for which Solar Impulse is grateful, a media alert issued by the Solar Impulse team said.

After departing  from Chongqing, the plane is  heading East toward the city of Fuling, located in the province of Sichuan in China.  Bertrand Piccard will fly over the mountainous region just outside Fuling between 12:00 pm and 1:00 pm local time  at a cruising altitude of 3,700 metres (12,140 feet). Piccard will continue Easterly, crossing the longest river in Asia, the Yangtze River, then  flying North Easterly toward the city of Wuhan. The solar powered aircraft will pass over Chaohu Lake, one of the largest lakes in China at roughly 8:00 am local time. Piccard is expected to arrive in Nanjing  4am UAE time on Wednesday.

The plane  will remain in Nanjing for approximately 10 days, depending on favourable weather conditions, as a thorough check of the airplane is required before departing Nanjing to Hawaii (USA) for the Pacific Crossing,  which will last 5 days and 5 nights.

The seventh leg flight from  Nanjing for Hawaii in the US,  flying  across the Pacific Ocean, will be a feat that has never been accomplished with a zero-fuel airplane before. During the coming months, Piccard and Borschberg will stop in Phoenix, Arizona, and Northern Africa or Southern Europe before returning to Abu Dhabi to complete its circumnavigation of the world.

Swiss pilots, Bertrand Piccard (Initiator and chairman) and André Borschberg (Co-founder and CEO), continue their journey, travelling 35,000 kilometers around the globe accumulating 500 flight hours over 5 months to spread the message about clean technologies through a pioneering spirit.
