What two types of transfer lines does the AAFS use to receive fuel?

The AAFS (Aerial Bulk Fuel Delivery System) uses two types of transfer lines to efficiently and effectively receive fuel: the top laid line and the bottom laid line. The top laid line is designed to be positioned above the ground, making it suitable for areas where a quick setup and initial deployment are essential. This positioning allows for easier access and maintenance. In contrast, the bottom laid line is situated below the ground level, providing advantages in protection against environmental factors and potential damage, while also minimizing tripping hazards.

Understanding the operational context of these lines is crucial. They are specifically chosen based on operational requirements, terrain, and fuel transfer capacity. The top laid line enables rapid deployment in combat or tactical situations where time is of the essence, while the bottom laid line is more suited for longer-term installations where stability and protection are needed.

In the context of fuel transfer systems, recognizing these distinctions helps personnel in choosing the correct configuration for specific tactical scenarios, which is vital for maintaining the logistics and supply chain of fuel in military operations.
