The WSC is unique in the fact that it breaks the jump into two stages: wing suit mode and canopy mode. Also, in addition to the unit itself, there is an audible device that completes the WSC. During the freefall portion, the unit has a set activation speed of 45mph (20m/s). This lower activation speed should allow the unit to activate if, for some reason, the jumper enters a flat spin.
After the wing suit portion of the jump is completed and the jumper opens their main canopy, the unit enters canopy mode. After several seconds under canopy, the jumper is made aware that the switch in modes has been successful via a melodic tone generated by the WSC audible device. The canopy mode can be set to either Expert or Speed depending on the jumper’s needs.
The WSC can be recognized by the red button with the white Wing Suit Logo imprint on the control unit.
As long as the WSC works in Wing Suit Status, it activates the release unit at a vertical speed higher than approx. 45 mph (20 m/s) at an altitude of approx. 750 feet (225 meters) AGL and down to approx. 130 feet (40 meters). If between the altitude of approx. 6500 feet (2000
meters) and approx. 1500 feet (450 meters) AGL and descending with less than approx. 19 mph (8.5 m/s) but more than 5.6 mph (2.5 m/s) for more than 10 seconds (this duration can be altered. See chapter 4.4.6), then the WSC changes to Canopy Status with different activation criteria. Thereafter it will activate the release unit at approx. 750 feet (225 meters) and down to approx. 130 feet (40 meters) AGL if the vertical speed is higher than approx. 78 mph (35 m/s). This is the Expert mode and the WSC default setting. In the case that the WSC has been set to use the Speed mode instead of the Expert mode, then it will activate the release unit at an altitude of approx. 750 feet (225 meters) and down to approx. 330 feet (100 meters) AGL, if the vertical speed is higher than approx. 102 mph (46 m/s).
The WSC System consists of the WSC unit and the WSC Audio. The WSC unit and Audio are paired. Only these two will function together and both items carry the same serial number.
