John,
I did a few examples with your spreadsheet and all looks well, nice!
Gary,
Using a slide rule and/or the law of sines is perfectly fine, of course. However, once we give ourselves the permission to use an electronic calculating device, the distinction between what method is more or less complicated becomes less well defined in my opinion. In the end, you have four numbers on input and two numbers on output, no matter how you look at it.

The law of sines comes up with the same answer as does the MB-2A. Either of these other methods are less complicatd. As a suggestion, you should call the desired way to go as "course" not "heading." You sail (or fly) a heading which incorporates a correction angle (wind correction angle) so that you maintain the desired "course." "Heading is the direction in which the nose is pointing at the moment. "Course" is the direction of the line on the chart. gl --- On Fri, 11/11/11, Apache Runner <apacherunner@gmail.com> wrote:
