How many total pounds does gravity refueling add to the T-6A normal capacity?

Gravity refueling adds a total of 100 pounds to the T-6A's normal capacity. This process allows for additional fuel to be added directly to the aircraft's fuel system without using the traditional pressure refueling system. It's important to understand that this extra fuel capacity can be beneficial in extending the aircraft's operational range and flight duration. While other options may suggest different amounts of additional weight, the specific increase provided by gravity refueling is established at 100 pounds, making it a significant point for pilots and those involved in flight planning to consider.
