What is the inflated diameter of the GQ-5000 parachute?

The inflated diameter of the GQ-5000 parachute is 21 feet. This measurement is critical for understanding the parachute's performance and behavior during deployment and descent. A parachute's diameter directly affects its drag coefficient, descent rate, and stability. In the context of aircrew training and operations, familiarization with the specifications of the GQ-5000 parachute, including its inflated diameter, helps ensure that personnel can effectively utilize this equipment in emergency situations.

Understanding the options: the other diameters listed do not correspond to the actual design specifications of the GQ-5000, as they either represent parachutes not in this category or suggest sizes that would not provide the intended functionality and safety required by training and operational standards.
