Why should only rubber chocks be used?

Using only rubber chocks is essential to comply with safety regulations that are designed to protect both personnel and equipment during ground operations. Rubber chocks provide a reliable and effective means to secure aircraft in place, reducing the risk of accidental movement that could lead to accidents or injuries on the ramp. Safety regulations often specify the materials and type of chocks to be used, with rubber being preferred due to its non-slip properties and ability to withstand various weather conditions. Compliance with these regulations helps ensure a safe working environment and mitigates liability for the organization.

While other options mention important functions like preventing slipping, minimizing noise, and ensuring aircraft stability, the primary reason for the exclusive use of rubber chocks is the adherence to established safety standards that guide ground operations in aviation settings.
