What would happen if the main riser attached to the RSL breaks?

If the main riser attached to the RSL (Reserve Static Line) breaks, the primary function of the RSL comes into play. The RSL is designed to facilitate the automatic deployment of the reserve parachute when the main parachute is released or becomes non-functional. In this case, if the main riser breaks, the other riser would still be connected to the parachute harness and the reserve system. As a result, the reserve parachute deploys automatically, guided by the RSL, even though one side of the main riser is broken. This mechanism is a critical safety feature in parachuting that enhances the chances of a safe landing.

A jumper must always be prepared to operate under various malfunction scenarios, which includes understanding the potential outcomes of riser failure. In situations where parts of the main parachute system may fail, the RSL helps ensure that the reserve parachute is deployed effectively and in a timely manner to ensure safety.
