A method is disclosed herein. The method includes receiving, by a processor, an ejection command for ejecting an ejection seat from an aircraft; determining, by the processor, an airspeed and an altitude of the ejection seat; responsive to the altitude of the ejection seat indicating a second mode of operation, determining, by the processor, whether the airspeed of the ejection seat is at or above a first threshold and below a second threshold; and responsive to the airspeed of the ejection seat being at or above the first threshold and below the second threshold: sending, by the processor, a command to deploy a drogue parachute; and, responsive to a first predetermined time period expiring, sending, by the processor, a command to deploy a main parachute and sever the drogue parachute based on a variable drogue severance delay.

Graduated chute delay six mode ejection system

A roll stabilization system for an aircraft ejection seat may be provided. An integral seat sequencer may activate an ejection sequence causing an aircraft ejection seat to be ejected from an aircraft. In various instances, particularly with lighter occupants of the aircraft ejection seat, the aircraft ejection seat may begin a rotational movement. To ameliorate this rotational movement, a roll correction rocket motor is installed on the aircraft ejection seat and selectively activated by the integral seat sequencer in the event that an undesired rotational movement is detected.
