What is the function of the BAK-14 trough sections?

The function of the BAK-14 trough sections is to provide protected areas where the pendant can rest below the runway. This design ensures that the arresting gear system operates effectively without interfering with aircraft movement on the runway. The trough sections allow the pendant, which is the component that connects the arresting cable to the aircraft during landing, to remain securely positioned below the surface, thus avoiding any obstruction or damage that may occur if the pendant were exposed or unsupported. This protection is crucial for maintaining safety and efficiency in aircraft landings, particularly in operations requiring arresting gear systems.
