Final answer:
When securing KC-135 slide tie patches, a loop of appropriate size is formed to securely hold them in place.
Step-by-step explanation:
When securing the KC-135 slide tie patches, a loop of appropriate size is formed to ensure the patches are securely fastened. The size of the loop depends on the thickness of the material being secured and the strength necessary to hold it in place. The loop should be tight enough to keep the patches in position, but not so tight that it causes damage or deformation to the material.
