What action should be confirmed when handling the pitch disc during an elevator jam situation?

When handling the pitch disc during an elevator jam situation, ensuring a smooth pull and lock is critical for maintaining control and safety. This action involves carefully managing the aircraft’s control surfaces to avoid exacerbating the jam or causing sudden movements that could compromise flight stability. A smooth pull and lock help to maintain the integrity of the control mechanism, reducing the risk of further complications that could arise from abrupt actions.

In the context of an elevator jam, managing the pitch disc with precision is vital because it directly affects the aircraft's pitch control. While other choices involve important safety protocols and checks, they do not specifically address the immediate actions required to safely navigate through the jam situation. Confirming a smooth pull and lock prioritizes effective handling of the elevator controls, essential for the pilot to respond adequately during this critical phase.
