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.

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.

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). -- __________________________________________________________ Sign-up for your own personalized E-mail at Mail.com http://www.mail.com/?sr=signup Search Smarter - get the new eXact Search Bar for free! http://www.exactsearchbar.com/ -- Incoming mail is certified Virus Free.
