"Navigation without Numbers" seems a very interesting book.
The quoted example is very interesting: with L=41°, D=39° & T=105°, compute H=15°08.0' (with Z=309°), while the "hand drawn" value for A shows 75°, which would translate into H=15°, I would assume.
This drawing is fascinating. I need to study it in more detail.
