Here's what I'm working on today... who can figure out what I'm trying to accomplish? :g:

When you get it figured out please send me your results. I'll just chill and drink some coffee until then. :whistling:

Gee, it's been a while since Navigation 303 in flight school.

You're probably trying to plan a rather long (longer than a Scout hike) horizontal traverse over a geographical plane. The maps you have need to be compensated for the Mercator Projection on a globe in order to follow a true Rhumb line to realize 'real world data' for the planning phase. You know, over a sphere, Pythagoras is wrong; the shortest distance between two points is a curved line. Wear heavy wool.

Here's the graph of the equation if it's any help;

Ironically, if you turn the graph 90 degrees, you can plot the new administration's economic performance since the inauguration.

The resultant curve is what we call in other aviation vernacular; Flying Blind.

Demsey nails it! I knew the old celestial nav training would come through.

It's a Gudermannian transform of sorts... "real" latitude as a function of "fake" latitude on a Mercator projection. Toss in a transform for Mercator loxodromes and you're home and dry.

Pack lots of wool! :tu:
