Which of the following is NOT a safety feature of the A-21 cargo bag?

The A-21 cargo bag incorporates several safety features to ensure the safe transport and deployment of cargo. Among these features, automatic deployment is not a standard characteristic of the A-21 cargo bag. Instead, the bag relies on manual methods to release or deploy the cargo, emphasizing the need for jumpers to maintain control over the deployment process.

Safety Fork and Lanyard, along with the turn-to-unlock and strike/press-to-release mechanisms, are important features designed to prevent accidental releases and ensure that cargo remains secure until the jumper is ready to deploy it intentionally. These mechanisms enhance the safety of the operation, ensuring that the jumpmaster can manage the payload effectively during various phases of the jump. The absence of automatic deployment in the A-21 cargo bag underscores the importance of active human involvement in the deployment process to mitigate risks associated with parachute operations.
