Abstract: A multi-staged suspension line length parachute may include a suspension line having a primary length and a secondary length. The primary length may be deployable upon a first deployment of the multi-staged suspension line length parachute. The secondary length may be prevented from deployment until the primary length has fully deployed. An attenuator may attach a first portion of the secondary length to a second portion of the secondary length.
