Subject: [NavList] Re: That darned old cocked hat


The augument of the math of the cocked hat is over my head. I would offer
my experence with the problem, but no soild solution. Part of my piloting
technique is how to treat the hat from the compass error. If by facing each
bearing NAVAID that are with in 180 degree of each other the error LOP of 3
or more NAVAIDS with the compass error will pass you to the right (EAST
ERROR)or the left (if WEST ERROR) for sure You will not be in the triangle
unless the error is mostly random. You will also be closer to the LOP'S of
the closer NAVAID. The same idea
with the CELSTRAL cocked hat.bodies being with-in 180 degrees, if you
measure high or low they will go over head or short, you will not be in the
triangle.
With an underway fix as I have seen. I would pick what I felt to be good,
with a lean towards the LOP'S closer to 90 degrees spred. HOW could I be
wrong?
