Air flow (wind) - directional movement of air masses with a certain speed.
1) Fans rotate and create wind.
2) Wind goes to the flight chamber via bottom circuit path and come back to the fans via upper circuit path.
We can adjust any fan power from 0% till 100% which is create a wind speed from 0 km/hour till 300 km/hour (0 mph till 186 mph).
For example:
- The fan power at 30% in wind tunnel №1 generates a wind speed of 90 km/h (55 mph).
- The fan power at 50% in wind tunnel №1 generates a wind speed of 150 km/h (93 mph).
- The fan power at 70% in wind tunnel №1 generates a wind speed of 210 km/h (130 mph).
- The fan power at 100% in wind tunnel №1 generates a wind speed of 300 km/h (186 mph).
In different windtunnels the fan power percentage are equal to different wind speeds.
For example:
- The fan power at 70% in wind tunnel №1 generates a wind speed of 210 km/h (130 mph).
- The fan power at 70% in wind tunnel №2 generates a wind speed of 225 km/h (140 mph).
Wind speed can be conditionally divided into main 3 categories:
1. Low wind speed - it’s comfortable to fly in the
Flying Squirrel or Hammock positions.
1. Low wind speed - it’s comfortable to fly in the
Flying Squirrel or Hammock positions.
2. Middle wind speed - it’s comfortable to fly in the
Wire (right side) or Wire (left side) positions.
2. Middle wind speed - it’s comfortable to fly in the
Wire (right side) or Wire (left side) positions.
3. High wind speed - it’s comfortable to fly in the
Soldier or Slingshot positions.
3. High wind speed - it’s comfortable to fly in the
Soldier or Slingshot positions.
Following these rules, one can also define additional wind speeds:
- Extra-low (very low) – before low
- Low-middle – between low and middle
- Middle-high – between middle and high
- Extra-high (very high) – after high

For different people the same wind speed can feels different - depending body parameters!
For example:
The fan power at 70% in wind tunnel №1 generates a wind speed of 210 km/h (130 mph).
Two bodyflyers are flying simultaneously in the flight chamber:
- Green bodyflyer keeps Soldier position in a static mode and for him it is feels like a high wind speed!
- Peach bodyflyer keeps Flying Squirrel position in a static mode and for him it is feels like a low wind speed!
This is because the green bodyflyer is much lighter than the peach bodyflyer. Therefore, for the peach bodyflyer to fly in the Soldier position, he needs significantly more wind. Most likely, the green bodyflyer won’t even be able to be inside the chamber, as it would be dangerous for him.
for the average persons!
- Belly neutral position
Low wind speed
190 km/h (118 mph) - Sit position
Middle wind speed
215 km/h (134 mph) - Bear position
High wind speed
245 km/h (152 mph)
It is fair to say that as your bodyflying skills improve, your perception of wind speed will change compared to the initial levels - the wind will feel softer and more pleasant! Among other things, the speed of the wind can also feel different depending on the air temperature and in humidity!
At the same wind speed, different humidity and temperature can change how the same element feels. Sometimes, the wind pressure may be too weak to complete the element, or too strong, making it impossible to perform!
