Are sectional paths correct across "long" distances?

RHUMB LINE. A line on the surface of the earth making the same oblique
angle with all meridians; a loxodrome or loxodromic curve spirals toward
the poles in a constant true direction. Parallels and meridians, which
also maintain constant true directions, may be considered special cases
of the rhumb line. A rhumb line is a straight line on a Mercator
projection. Sometimes shortened to RHUMB. See also FICTITIOUS RHUMB LINE.

So, yup, you're right.

Thanks--and thanks for introducing me to the word "loxodromic," which
I had never heard.

And BTW, I do know how to spell "two."

The last time I remember flying a loxodromic spiral, I was practicing
NDB approaches for my CFI-I ride :-)

LOL! I know exactly what you mean!
