What equipment is typically used to prevent aircraft strikes during vehicle operations?

The use of pre-positioned wheel chocks is a critical safety measure in preventing aircraft strikes during vehicle operations. Wheel chocks are designed to secure vehicles in place, preventing them from rolling, especially when parked near active airfields. This is essential in areas where aircraft are operating, as unintended vehicle movement can create hazardous situations that might lead to accidents.

By effectively stabilizing vehicles, pre-positioned wheel chocks ensure that vehicles do not encroach into aircraft movement areas, thereby reducing the risk of collisions between ground vehicles and aircraft. This safety practice is particularly important in environments like airfields, where the presence of high-speed moving aircraft necessitates stringent safety protocols.

In contrast, hearing protection, traffic cones, and reflective vests serve different purposes. While they contribute to overall safety and awareness, they do not directly prevent aircraft strikes in the same manner that wheel chocks do. Hearing protection is essential for safeguarding against noise, traffic cones are used for traffic direction, and reflective vests enhance visibility but do not stop vehicle movement.
