How It Works?

How Tunnels works?
Four axial fans driven by electric motors with total power of 1,600 kilowatts create a strong vertical airflow with a maximum speed of more than 300 kilometres per hour (190 miles per hour). Even a 4VFS team flying head-down can comfortably acquire new skills in this kind of airflow.

Our tunnels utilize ZeroTurbulence® (patent-pending) technology, which eliminates even minor turbulence in the flight chamber, allowing all skydivers, even the most inexperienced, to feel the true sensations of skydiving.

The optimum design of the flight chamber, with its perfectly round shape, 4.5-metre diameter, and two levels of glass, makes it possible to fully enjoy dynamic flights at all speeds.

The innovative air conditioning system makes flying even more comfortable when it is hot outside, without annoying moisture or cold spots.

Flight chamber

Flight Chamber
The flight chamber is 4.5 metres (14.76 feet) in diameter, with a total height of 19.4 metres.

It is perfectly round in shape, allowing flyers to use the space fully while bodyflying.

The curved, high-strength glass ensures the safety of flyers and makes it easy for spectators to observe the action. The glass in the flight chamber is two levels high, with a glass floor separating the levels.

Access to the antechamber is provided through pressure doors. The doors can be opened or closed at any time, as this does not affect the wind stream.
