What is the unusable fuel and CG location for a Cessna 208B with a specific modification?

The correct answer identifies the unusable fuel weight of 24.1 lbs and its center of gravity (CG) location at +206.4 inches. This information is essential, especially for operations such as weight and balance calculations, which are critical for ensuring the safe operation of the aircraft.

The unusable fuel weight is the amount of fuel that cannot be used for flight due to the design of the fuel system, meaning that even when the fuel gauges indicate a certain amount of fuel, a portion will remain in the tanks that cannot be drawn upon by the engines. This plays a crucial role in determining the maximum takeoff weight and the overall balance of the aircraft when loaded.

The CG location is just as critical, as it affects the aircraft's stability and control. A CG position that is too far forward or too far aft can lead to adverse flight characteristics. Knowing the specific weights and locations helps pilots and maintenance personnel ensure that the aircraft remains within safe operational limits.

In the case of the Cessna 208B with the specified modification, the correct unusable fuel amount and its CG location align with the aircraft's design specifications and performance limits, providing accurate information for safe flight operations.
