Which of the following is NOT a major component of the T-11 reserve parachute?

The main closing loop is not a component of the T-11 reserve parachute, which is why this choice is the correct answer. The T-11 parachute system has specific components that focus solely on the reserve parachute's functionality.

The reserve closing loop is critical as it secures the reserve parachute in its container until it is deployed in an emergency. The ripcord assembly is vital for deploying the reserve parachute; it activates the mechanism that opens the reserve container and releases the parachute. The reserve extractor works to initiate the deployment of the reserve parachute by pulling it out of the container.

These functions are directly related to the operational aspects of the reserve parachute, ensuring that if the main parachute fails, the reserve can be deployed safely. In contrast, the main closing loop pertains specifically to the primary parachute system and does not have any role in the functioning of the reserve parachute.
