RealFly Flight Simulator

Simulator technology

Imagine the power of a domesticated hurricane, concentrated in a monumental glass cylinder. The beating heart of RealFly is a state-of-the-art wind tunnel, where four ultra-efficient turbines generate a powerful vertical airflow, faithfully recreating the sensation of freefall, but without the constraints of altitude or piloting.

Construction of RealFly Sion began in April 2013 and took almost a year to complete. Standing 24 metres high, the RealFly “wind tunnel” is Switzerland’s first indoor freefall simulator, and can accommodate up to four people in flight simultaneously. The 4.35-meter-diameter flight chamber consists of a set of 5-meter-high glass walls, with a ride height of 14 meters.


Flight preparation

Each participant is carefully prepared by our certified and experienced instructors. You’ll receive a briefing, learn the basic flying techniques, the moves your coach will show you during the activity (raise your head, bend your legs, stretch your legs, relax, smile :P) and the essential safety instructions. Equipped with a wetsuit, helmet, goggles and earplugs, you’ll be ready for an unforgettable experience that ends with a personalized certificate and, if you wish, photos and videos of your session.


The sensation of flight

Once inside the simulator, the experience becomes totally immersive. Participants feel an incredible sense of freedom, experiencing the power of the wind at almost 200km/h. Coaches will guide them to find the right “neutral belly flying position”, so they can try flying on their own.
Indoor skydiving is a sport accessible to all. That’s right! You don’t have to be a champion to float in a wind tunnel, as this activity is accessible to the whole family from 5 years old.
With RealFly, you can experience indoor skydiving without having to worry about weather conditions.
