The vertical fin of a single engined aircraft is
- parallel with both the longitudinal axis and vertical axis.
- parallel with the longitudinal axis but not the vertical axis.
- parallel with the vertical axis but not the longitudinal axis.
Explanation
The vertical fin lies in the aircraft's plane of symmetry, so its surface is aligned with both the longitudinal axis running nose to tail and the vertical (normal) axis. This symmetrical placement means it produces no side force in straight flight and provides directional stability and yaw damping.
manin asking:
isn't the fin for single engine aircraft is parallel to virtical axis and offset to the left of the longitudinal axia,

Yes, it is. But there is no such answer, so you must select most correct one. Btw, not all aircrafts has fin offset. Basically fin is parallel to longitudinal and vertical axes.
