How many rubber support blocks does the BAK-14 System use to support the pendant above the runway service?

The BAK-14 System incorporates a specific design that utilizes rubber support blocks to maintain the stability and positioning of the pendant above the runway service. The correct count of rubber support blocks is crucial for ensuring that the pendant achieves the necessary alignment and support to function effectively.

In this case, the BAK-14 System is designed to use 14 or 20 rubber support blocks. This configuration ensures that there is adequate support and distribution of weight, which is essential for maintaining operational efficiency and safety during aircraft landing and takeoff operations. The precise number within this range reflects the design requirements and engineering standards intended to accommodate various scenarios that the system may encounter in service.

The other options suggest different counts that do not align with the specifications set for the BAK-14 System, highlighting the importance of understanding the correct technical requirements for effective system performance.
