Next message: Lars Bergman (HF/ESE): "Re: Advancing a position circle. was : [NAV-L] Position from crossing two circles"
I wrote earlier:
"...the courses as drawn are not due north (particularly the outer ones),
but isn't that due to lines of longitude converging towards the pole? The
displaced circle hasn't been distorted at all.."
However, if each point of the radii is moved north by the same distance then
the new circles formed from those points will certainly be deformed. And,
when approaching the pole, since by definition north finishes there, I can
even envisage the J curve.
But again, isn't all of this simply due to converging lines of longitude?
Is that what all this is about?
