    It's painful that world's most specialized community cannot find an agreement about the loxodrome. The one part asserts that loxodrome reaches the pole after an infinite number of revolvings, but along the finite path, the other part denies the possibility of it and assumes the asymptotic behavior of loxodromes, meridians and parallels excepted.

    It is may be a good time to go to a Naval Academy to learn a bit of this.
    I do not know how the Navy officer are trained, in France we use : "cours de Navigation à l'usage des candidats officiers de marine".
    In book I, Lesson 5, all (and a bit more) about loxodromes on sphere and ellipsoid.
    In book IV, extended theory about logarithmic spirals.
    In the gunnery book, tracks to attack fixed targets, exercice 85 : logarithmic spiral tracks.

    And, at least, a meridian is not a loxodrome but an orthodrome (great circle track).
