I attach the plot of a simulated flight (left) and of the mapping in lat/lon (left). In the simulation, the flight follows a path that only changes on the X-axis (straight line). All axii are in meters.
If X is longitude and Y is latitude, why is the behavior of the direct solution so erratic? (at least at high altitudes). I'm computing the azimuth in degrees clockwise from the Y+ axis.
I'm using the direct solution of this toolbox:

The results are similar when using the following aviation formula:

Any insights?
Prof. Karney, you were right. I was doing somthing stupid in my code when calculating azimuth. The behaviour is now well behaved.
The flight trajectory model which outputs in meters is now properly mirrored in the geodetic path. Cartesian model starts at (0,0,16000) = (13.378932, -89.962463, 16000) in geodetic.
Thanks for your code and paper. Does the job great.
