-The cabin slenderness ratio describes the ratio of cabin width to cabin length $\frac{w_{cabin}}{l_{cabin}}$.

 ### Fuselage diameters
 The fuselage does not necessarily have a circular cross-section. It is more common to design elliptical cross-sections. Because of that, there are several values that must be determined:
+
 - Fuselage diameter in y-direction
 - Fuselage diameter in negative z-direction
 - Fuselage diameter in positive z-direction
 
 #### Fuselage diameter in y-direction
-The fuselage diameter in y-direction $d_{fuselage\_y}$ can be calculated in the following way:
-$
-    d_{fuselage\_y} = w_{cabin} + 2 \cdot t_{wall}
-$
+The fuselage diameter in y-direction $d_{\text{fuselage,y}}$ can be calculated in the following way:

 #### Fuselage diameter in negative z-direction

+The fuselage diameter in negative z-direction $d_{\text{fuselage,z,neg}}$ is determined by the cargo accommodation. It can be calculated in the following way.
+
 At first, the distance to the cargo bottom is calculated:
-$
-    d_{to\_cargo\_bottom} = h_{max} + t_{floor} + d_{container\_to\_ceil} + o_{cabin\_floor}
-$
+$$
+    d_{\text{to cargo bottom}} = h_{\text{ULD,max}} + t_{\text{floor}} + d_{\text{container to ceil}} + o_{\text{cabin floor}}
+$$
 
 In which
-- $h_{max}$ - maximum height of unit load device
-- $d_{container\_to\_ceil}$ - distance from the container to the ceiling
-- $o_{cabin\_floor}$ - offset cabin floor
+
+- $h_{\text{ULD,max}}$ - maximum height of unit load device
+- $t_{\text{floor}}$ - floor thickness
+- $d_{\text{container to ceil}}$ - distance from the container to the ceiling
+- $o_{\text{cabin floor}}$ - offset cabin floor
 
 Afterwards, the distance to the lower compartment edge is estimated:
-$
-    d_{to\_lower\_compartment\_edge} = d_{container\_to\_wall} + 0.5 \cdot w_{max\_at\_base}
-$
+$$
+    d_{\text{to lower compartment edge}} = d_{\text{container to wall}} + 0.5 \cdot w_{\text{base,max}}
+$$
 In which
-- $d_{container\_to\_wall}$ - distance from container to wall
-- $w_{max\_at\_base}$ - maximum width at container base
+- $d_{\text{container to wall}}$ - distance from container to wall
+- $w_{\text{base,max}}$ - maximum width at container base
 
 Based on the Pythagorean theorem, the inner fuselage diameter (that equals the hypotenuse) can be calculated:
-$
-    d_{inner\_fuselage\_z\_neg} = \sqrt{(d_{to\_cargo\_bottom})^2 + (d_{to\_lower\_compartment\_edge})^2}
-$
+$$
+    d_{\text{fuselage,z,neg,inner}} = \sqrt{(d_{\text{to cargo bottom}})^2 + (d_{\text{to lower compartment edge}})^2}
+$$
 
 Adding the wall thickness results in the fuselage diameter in negative z-direction:
-$
-    d_{fuselage\_z\_neg} = d_{inner\_fuselage\_z\_neg} + t_{wall}
-$
+$$
+    d_{\text{fuselage,z,neg}} = d_{\text{fuselage,z,neg,inner}} + t_{\text{wall}}
+$$
 
 #### Fuselage diameter in positive z-direction
-The fuselage diameter in positive z-direction $d_{fuselage\_z\_pos}$ is determined by the passenger accommodation. It can be calculated in the following way.
+The fuselage diameter in positive z-direction $d_{\text{fuselage,z,pos}}$ is determined by the passenger accommodation. It can be calculated in the following way.
+
 Firstly, the inner fuselage height (equals outer cabin height) can be determined:
-$
-    d_{inner\_fuselage\_z\_pos} = h_{aisle\_standing} - o_{cabin\_floor} + h_{system\_bay}
-$
+$$
+    d_{\text{fuselage,z,pos,inner}} = h_{\text{aisle,standing}} - o_{\text{cabin floor}} + h_{\text{system bay}}
+$$
 
 In which
-- $h_{aisle\_standing}$ - passenger aisle standing height
-- $o_{cabin\_floor}$ - cabin floor offset
-- $h_{system\_bay}$ - system bay height above cabin
+
+- $h_{\text{aisle,standing}}$ - passenger aisle standing height
+- $o_{\text{cabin floor}}$ - cabin floor offset
+- $h_{\text{system bay}}$ - system bay height above cabin
 
 Adding the wall thickness leads to the fuselage diameter in positive z-direction.
-$
-    d_{fuselage\_z\_pos} = d_{inner\_fuselage\_z\_pos} + t_{wall}
-$
+$$
+    d_{\text{fuselage,z,pos}} = d_{\text{fuselage,z,pos,inner}} + t_{\text{wall}}
+$$
 
 ### Fuselage height
 The total height of the fuselage can be determined by summing up the fuselage diameters in positive and negative z-direction:
-$
-    h_{fuselage} = d_{fuselage\_z\_pos} + d_{fuselage\_z\_neg}
-$
+$$
+    h_{\text{fuselage}} = d_{\text{fuselage,z,pos}} + d_{\text{fuselage,z,neg}}
+$$
 
 !!! note 
     If the `force_circle_cross_section` mode is selected, fuselage height and width are set to the maximum of both.

 ## Generate fuselage shape {#generate-shape}

 The aircraft is divided into three sections: A cockpit section, followed by a constant section, and the tail section. 
 The steps of the shape generation are basically the same for all aircraft sections:

 1. Calculate the section length as a percentage of the fuselage length<sup>*</sup>.
 2. Proportionally adjust the given reference geometry to match the actual geometry using scaling factors. Therefore, separate scaling factors are calculated for
