def plot_airfoil(airfoil_paths,

"""
Creates a 2D visualization of airfoil geometries from coordinate files.
Parameters
----------
airfoil_paths : list of str
Paths to airfoil coordinate files
save_figure : bool, optional
Flag for saving the figure (default: False)
save_filename : str, optional
Name of file for saved figure (default: "Airfoil_Geometry")
file_type : str, optional
File extension for saved figure (default: ".png")
width : float, optional
Figure width in inches (default: 11)
height : float, optional
Figure height in inches (default: 7)
Returns
-------
fig : matplotlib.figure.Figure
Handle to the generated figure
Notes
-----
Creates a plot showing:
- Airfoil surface coordinates
- Equal axis scaling
- Optional figure saving
**Major Assumptions**
* Coordinate files are properly formatted
* Coordinates are normalized by chord
* Points are ordered from trailing edge clockwise
**Definitions**
'Chord'
Line from leading edge to trailing edge
'Thickness'
Distance between upper and lower surface
