Tack så mycket, Willi, thank you!
That's an idea.
My question arose from reading pages 23, 24 and 25 here (at The Astrolabe Project). The author mentioned rather intricate methods to calculate the azimuth more precisely. I wondered, could it be done by the Haversines?
I'll try the Somner-Line approach suggested by you, because it is possible to draw the perpendicular to the secant line connecting the two latitudes.
But still - the original two-step All-Haversine Doniol looks less complicated. :)
Warm regards,
