Ejection seats may be safetied by performing all the following except?

The correct response to the question indicates that pulling the face curtain above the ejection seat does not serve as a method of safing the ejection seats. Safing procedures are specifically designed to ensure that the ejection mechanisms cannot inadvertently activate. Effective safing involves actions that prevent the firing sequence of the ejection system or provide physical barriers to prevent accidental deployment.

Interrupting the firing sequence and inserting pins in the ejection seat handles are direct safety measures. These actions either stop the seat from being deployed under normal circumstances or create a physical block to the ejection mechanism. Cutting the initiator hose likewise functions as a crucial step in deactivating the ejection system, effectively preventing the seat from firing.

On the other hand, pulling the face curtain above the ejection seat does not contribute to safety. The face curtain is primarily designed to protect the ejection seat occupant during the deployment of the seat and does not interfere with the mechanics of the ejection system or affect its functionality. Thus, it does not align with the necessary procedures to ensure the seat is safed.
