Final answer:
The weight of the drogue riser assembly in the ACES II ejection seat system is not widely published and may be subject to security regulations. For accurate data, consult the equipment manuals or contact the manufacturer, ensuring compliance with all guidelines.
Step-by-step explanation:
The weight of the drogue riser assembly used in the Advanced Concept Ejection Seat II, commonly known as ACES II, is a specific figure that relates to the ejection seat components used in military aviation. Normally, such detailed specifications are given in the equipment manuals or product specification sheets. However, for security reasons, the exact weight of these components may not be widely published. If you are interested in this for academic purposes or design considerations, I would recommend consulting the manufacturer's data or the technical documentation of the ACES II ejection seat system. Ensure that any handling of such data complies with applicable regulations and security guidelines.
