A multi-modal aircraft recovery system is disclosed. In various embodiments, the system includes a first aircraft recovery parachute having a first set of physical attributes optimized for a first set of conditions and a second aircraft recovery parachute having a second set of physical attributes optimized for a second set of conditions different from the first.

A sequencer system for an ejection assembly may comprise a first A-side controller and a second A-side controller in operable communication with the first A-side controller. A first B-side controller may be in operable communication with the first A-side controller. A second B-side controller may be in operable communication with the first B-side controller and the second A-side controller. The controllers may be configured to each make an initial ejection sequence determination and a verified ejection sequence determination. The controllers may make the verified ejection seat determination based on a two of three voting scheme.

A trap system is presented for deployment of a reserve parachute. The trap system includes a trap line with a first end coupled to a main parachute and a trap attached to a surface of the container. The trap includes an outer perimeter to removably hold the trap line and an interior to removably hold the reserve bridle. A kit is also presented for converting a parachute container into an improved parachute container to deploy a reserve parachute. The kit includes an attachment to be secured to a surface of the parachute container. The attachment includes a trap line with a first end configured to be coupled to the first end of the RSL lanyard, and a trap secured to a region of the attachment, with an outer perimeter to removably hold a second end of the trap line and an interior to removably hold the reserve bridle.

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.

A selection is made between single stage and multistage parachute deployment for a vehicle based at least in part on vehicle state information. In the event multistage parachute deployment is selected, a drogue parachute is deployed during a first deployment stage and afterwards, a main parachute is deployed during a second deployment stage. In the event single stage parachute deployment is selected, at least the main parachute is deployed in a single stage where in the event the drogue parachute is deployed during the single stage, the drogue and main parachute are deployed simultaneously.
