Where to Put It: Is Stabilizer Position Wisdom or Whim?

Designers just seem to put the aerodynamic element wherever seems convenient.

Key Takeaways:

Airplane stabilizer placement varies widely and is often influenced by factors like structural simplicity, ease of assembly, and fuselage shape, rather than subtle aerodynamic considerations.
The author's research on the angle between wing and stabilizer centers of pressure yielded no clear aerodynamic explanations for diverse placements.
Aircraft design decisions for features like stabilizer location or T-tails are frequently driven by aesthetics, marketing, or practical issues (e.g., jet engine exhaust clearance), rather than solely by aerodynamic optimization.
Many modern designs overlook classical advice on tail configurations that would improve rudder effectiveness and spin recovery characteristics.

Practically all airplanes—flying wings and biplanes are exceptions—have two wings in tandem. Unless the wings are nearly the same size—a very uncommon arrangement—only one of them is honored with the name “wing.” The other is demoted to the rank of “stabilizer” or “canard.”

Canards raise uncomfortable philosophical and anatomical questions by conflating the “tail” and the “nose,” but at least they have had the salutary effect of dispelling many pilots’ mistaken belief that they understand longitudinal stability. The convenient analogy between a conventional empennage and the feathers of an arrow falters when the feathers are found on the pointy end of the arrow.
