For aircraft with extended range tanks, what is the total fuel load when using JP-8?

When considering the total fuel load for aircraft equipped with extended range tanks using JP-8, it is essential to account for both the standard fuel capacity and any additional capacity provided by the extended range tanks.

The C-17 Globemaster III, which operates with JP-8, has a maximum fuel capacity when utilizing all available fuel tanks, including the extended range tanks. The total capacity, when these tanks are filled with JP-8, reaches 244,600 pounds. This figure is crucial for mission planning, as it dictates the aircraft's range and operational capabilities, especially for long-haul missions where fuel efficiency and need for extended travel are essential.

In the context of the question, recognizing that JP-8 is a kerosene-based fuel commonly used in military and commercial aircraft is also important. Understanding fuel types is fundamental because they can impact operational parameters including the maximum takeoff weight and payload capabilities.

The other options presented do not reflect the correct total fuel load when all extended range tanks are fully filled with JP-8, making "244,600 pounds" the accurate answer for this particular aircraft configuration.
