    Re: 30 minute HO229 error

    Given that you are right in the middle of the tabulated latitudes, it you are probably in the ballpark with 30 mile intercept.  However, without the actual data, it's not possible to say for sure.
     
    Have you plotted your line to see how close the line is to your GPS fix?
     
    With tables, the error is easily seen in the plotting, by formula, you can see in the figures.

    Hi,

    When I use HO229 in florida at 27 1/2 N lat. I'm rounding to whole degree and When I'm done, I'm out by about that 30 miles, what the heck am I doing wrong???

    I'm 4 years into Celestial Nav and can use cosine method and have gotten perfect readings every time to a mile or so from my boat.
    but that darn HO229, can't git it??

    Help
    Eddie
