Which option is NOT one of the fuselage types listed, by name?

• A. Geodesic
• B. Truss
• C. Monocoque
• D. Semimonocoque

Answer: (A)

Fuselage construction is typically categorized by how the load is carried: skin-only (monocoque), skin plus supporting members (semi-monocoque), or an internal framework (truss). The three common named types you’ll see are monocoque, semi-monocoque, and truss because they describe the main ways the structure handles bending and torsion loads. Geodesic, while it represents a lattice-style approach used in some designs, isn’t a standard fuselage type listed by name in most aircraft-maintenance references. Therefore, geodesic is the option that is not listed by name.
