You had me stumped. I read and re-read the example on my website and didn't see the error that you pointed out. The declination is 20 N in the example there: "The Bygrave doesn't require that the latitude or the LHA to be whole degrees so you can compute altitude (Hc) for your Dead Reckoned position but for convenience in this example we will use whole degrees, 34º North for latitude, 20º North for declination and a Local Hour Angle (LHA) of 346º." https://sites.google.com/site/fredienoonan/other-flight-navigation-information/modern-bygrave-slide-rule I then looked at the PDF copy available on the website and there the error is so you must be looking at that copy. Thanks for finding that typo for me, I will fix it. gl --- On Wed, 11/14/12, hanno ix <hannoix@att.net> wrote:
