Use in parachuting

Static lines are used in order to make sure that a parachute is deployed immediately after leaving the plane, regardless of actions taken or not taken by the parachutist. However the parachutist must adopt and maintain a suitable body position throughout deployment to minimise the chances of a parachute malfunction. This method of parachute deployment is commonly used in several ways:
  • Training student skydivers
  • BASE jumping

    s jumping from very low altitudes (400+ feet or 122+ meters)


Static line jumping carries risk of injury that, according to one study, doubles when performed in combat.

For training students in civilian operations, modifications to existing static line equipment may be made to simplify operations. One such modification is to attach the deployment bag to the parachute instead of the static line, which also requires some modification to allow the static line to detach, typically a Velcro
