Is pressure pattern navigation used in the real world? How effective is it really? Pressure Pattern Navigation is a method of capturing favorable tailwinds when flying long-distance trips.

The basic methodology can be found in this PDF.

Does pressure pattern navigation work in the real world? How effective is it?
It is used in the real world, especially by airlines. The best example is the North Atlantic Track system. The tracks are tailored every day to maximize the tailwind on West to East crossings and minimize the headwind East to West crossings.
