Dimensions and technical parameters of this tunnel offer the best conditions for the professional requirements on speed, space and height. Its size provides ample space for the entire training even of group formations of eight skydivers. Tunnel with 4,3 m of flying chamber diameter is the perfect place for training of army parachutes and special troops with their specific equipment. From tourist's point of view, the tunnel offers comfortable space even for flying couples with instructors or other smaller groups.

Thanks to a comprehensive fan optimization the, tunnel allows operation of profi-flights as well as fun-flights at very low operation costs.
