Solar Impulse 2, the world's biggest solar airplane, is expected to land in Southwest China's Chongqing on March 27 at the earliest.

The single-seat aircraft landed in Myanmar's second largest city of Mandalay on March 19 after it completed the fourth leg of its world tour powered solely by the sun.

As scheduled, the plane will remain in Myanmar for several days before leaving for Chongqing on March 26. However, the solar plane's trip itinerary is limited to weather. A recent weather report from Chongqing shows that a short sunny day will occur on March 27.

Though the exact time of landing is not certain, Chongqing Airport has already begun preparing. A temporary hangar is being constructed to provide better maintenance service to the solar plane.

According to the flying schedule, the plane will spend about one month in Nanjing, the capital of Jiangsu province. After that, Solar Impulse will attempt a 5 day flight across the vast Pacific Ocean to Hawaii.

The total flying time of the circumnavigation trip will be around 25 days, spread out over five months, with a total flying distance of 35,000 kilometers.
