I think there is a TeX.SE question that deals with this. The details are not clear to me, but it appears that with a little work you can use TikZ with LaTeX to draw a plane:
This TeX.SE example used a variety of tools including Inkscape, Sketch, Blender, and Cinema4D (of which only Cinema4D is not FOSS) to produce:
From what I can piece together from this TeX.SE answer, details of how the above diagrams are made is available in Italian here. A Google Translate version of the abstract is:
This article shows how you can use the power of LATEX and PSTricks and TikZ packages in the production of advanced illustrations . The creation of designs that represent the three-dimensional scenes with directions of scientific content is made possible with LATEX . The author shows how it is able to manipulate and arrange three-dimensional objects in a scene with the program Sketch of Eugene Ressler edil its intuitive scripting language , getting a ' output in the form of PSTricks or TikZ commands . The proposed working method allows to overcome the limitations that users of a package as PSTricks , which also has relatively advanced three-dimensional drawing capabilities , meet whenever are going to want to draw and manipulate three-dimensional scenes containing objects simple and primitive .
The teaching of a subject such as engineering Flight Dynamics is a field in which he operates, and which they refer to the specific examples given in the article
which suggests that Cinema4D may not be critical.
