What size pendant is typically used on operational installations of the BAK-12 arresting system?

The correct choice is based on standard practices regarding the BAK-12 arresting system, which is often used for aircraft recovery on runways. The typical size of the pendant used in operational installations of this system is 1 1/4 inch. This specific size is designed to ensure proper functionality and safety during operations, as it allows for adequate strength and flexibility while withstanding the forces exerted during aircraft landings and recoveries.

Selecting the appropriate pendant size is crucial for the reliability and effectiveness of the BAK-12. A pendant that is too small might not handle the exerted forces, leading to potential failures, while a larger size could introduce unnecessary weight and complicate deployment and usage. Therefore, understanding the specifications of the BAK-12 system and adhering to the recommended pendant size is essential for safe and efficient operations.
