C-17 Copilot Airdrop (CPAD) Practice Test

Publications used for rigging and airdrop equipment are organized by topic within a coding system. The actuator arm is a specific component of the cargo release/rigging mechanism, and its detailed guidance is found in the 13C7-1 series. Within that series, the final digit points to the exact component, and 5 corresponds to the actuator arm. So, the publication that explains the actuator arm is the one in the 13C7-1-5 set. The other options belong to different topics or sections and do not specifically cover the actuator arm.
