    It would be nice to study titles you refer. Only to find them anywhere out of 
    France. The language would not make troubles.
    And, at least, meridian is both the orthodrome and the loxodrome (special 
    type). Can you deny that it holds the steady angle with the meridian? The 
    same is valid for the equator. Search in your "Cours de navigation",  book I, 
    Lesson 5, for a while.

    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 ? 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).
