 2. **Installation placement**: The LD3-45 container is positioned 10 cm behind the end of the landing gear bay, aligning approximately with the trailing edge of the wing.
 3. **Container data**: The volume and dimensions of the LD3-45 container are predefined and referenced from the Lufthansa Cargo website<sup>[2]</sup>.
 
-The energy contained in an additional center tank is calculated by first determining the usable volume and then taking into account the volumetric energy density of kerosene. With the known factors $ f_{\text{volume,usable}}$ and $a_{\text{temperature,expansion}}$, the usable volume of an additional center tank results in $V_{\text{ACT,usable}} = 3,068.5\text{ L}$ which is equal to an energy amount of $ E_{\text{ACT}} = 99,189,262.5\text{ MJ}$.

 #### Limitations
 **Single Center Tank Limit:** The program currently supports the calculation of only one additional center tank. Attempts to add more tanks will not be processed.
