At PrivateFly, we love looking ahead to innovations that will change the aviation industry. We’ve been closely following the progress of the Solar Impulse 2, an aircraft that can ‘fly forever’ without fuel.

This week, they announced the route they will shortly take on its five-month round the world flight, set to take place at the end of February or early March. The Solar Impulse 2 has already taken test flights across the US, but this journey will see it fly across the sea for the first time.

With a wingspan bigger than a Boeing 747, but the weight of a car, the Solar Impulse 2 can stay in flight for five days at a time. This is made possible due to its solar skin, over 17,000 solar cells that supply its four electric motors with renewable energy. And it also has a storage battery, so the ultralight plane can keep flying in the dark.

This round the world journey will be an enduring test for both the aircraft and the pilots (who will take turns to fly the single-seat aircraft). But behind the single pilot aircraft, there is a support team of 60 people who are working to make this happen.

But the pilots are up for the challenge. Bertand Piccard is also a Psychiatrist, who captained the first non-stop balloon flight around the world. André Borschberg is an Engineer who trained as a Swiss air Force pilot. He is also a business Entrepreneur with 8 solar flight world records to his name.

The cockpit measures 3.8m3, and the pilot will have oxygen supplies, food and equipment to survive for 5 days in non-stop flight. The seat doubles up as both bed and toilet, with thermal insulation protecting them from temperatures ranging from -40 – +40 degrees centigrade.

The route, just announced, will set off from Abu Dhabi, heading East to Oman and then India. Then it will make stops in China before crossing the Pacific for stops in Hawaii and the Midwest before landing at New York JFK. From there, it will cross the Atlantic, making a landing in either North Africa or Southern Europe before completing its journey in Abu Dhabi five months later.

When the Solar Impulse sets off in just a few weeks’ time, we’ll be tracking its progress closely. This is an exciting step forward for the sustainable future of aviation without fuel, and a significant milestone in aviation history.
