What component is responsible for deploying the reserve canopy in the T-11 reserve parachute?

The component responsible for deploying the reserve canopy in the T-11 reserve parachute is the ripcord assembly. The ripcord assembly functions by enabling the user to pull a cord that triggers the deployment of the reserve parachute. When the ripcord is pulled, it releases the reserve canopy from its protective stowage, allowing it to inflate and provide a secondary means of descent.

This mechanism is critical in emergency situations where the main canopy may fail or malfunctions, ensuring the safety of the jumper. The design of the ripcord assembly allows for an immediate response, which is vital in emergencies where every second counts for a safe landing. Using the ripcord assembly effectively requires training and familiarity with the parachute system to ensure proper deployment under stress.

Other components, such as the reserve closing loop, ejector spring assembly, and reserve pack tray, play important roles in securing and housing the reserve parachute or facilitating its function. However, they do not directly deploy the canopy like the ripcord assembly does, which is why it is the correct choice in this context.
