Which components of the MA-1A arresting barrier provide slack for the arresting cable?

The deck hooks play a crucial role in providing slack for the arresting cable in the MA-1A arresting barrier system. When an aircraft engages the arresting cable, the hooks allow for some movement and give, which is essential for ensuring that the cable can absorb the initial energy and forces exerted during the landing. This slack helps to avoid damaging the cable and the aircraft while effectively bringing the aircraft to a safe stop.

In contrast, the other components do not serve the same function of providing slack. Anchor points are primarily responsible for securing the entire barrier system to the flight deck. Side supports help stabilize the structure but do not provide slack in the cable. Barrier straps are meant to hold the arresting cable in place but do not contribute to the necessary flexibility that the deck hooks provide during an aircraft’s landing.
