What is the primary purpose of the parachute pack on the C9 canopy?

The primary purpose of the parachute pack on the C9 canopy is to serve as a container for the canopy, pilot chute, and suspension lines. This container is essential for the proper deployment of the parachute; it secures these components together and protects them until they are needed during a jump. When the parachutist exits the aircraft, the pilot chute is extracted first, which subsequently pulls the main canopy out of the pack. This design ensures that the parachute deploys smoothly and efficiently, allowing for a safe descent.

The role of the parachute pack is crucial in the overall functionality of the parachute system. It helps to maintain organization and readiness of the equipment, significantly impacting the parachutist's safety and performance during both free fall and descent phases of the jump.
