Rolling moment in sideslip is generated by every item below except
Answer: B
Correct answer: The tailplane's area
The tailplane acts in the pitching plane, contributing to longitudinal stability and to the neutral point's position. Nothing about its area produces a rolling moment in a sideslip.
The other three all do. Geometric dihedral raises the lower wing's incidence; sweep gives the leading wing more lift; and the fin's side force acts above the rolling axis, so the surface that provides directional stability contributes a rolling moment too. That last is a useful reminder that the lateral and directional axes are coupled through the same sideslip.
