Greg, that is news to me about the NC-2, I have always assumed, probably falsely, that I was reading decimal degrees.   I have the manual at home and will have to look at it to double check.  That might explain some sunline deviations when i plot them (although my plots can hardly be accurate to the 0.1 degree anyhow.).  I certainly like tenths of minutes as well as that is one less conversion i have to do.

 

Still, this is not the source of my differences.  I tend to use the computer for a vast majority of my azimuth calculations because I can input magnetic heading, gyro heading, and declination and with a click of the mouse and find deviation, Compass error, and gyro error instead of having to do all of the conversions. on paper.  Besides, the computer has the almanac built in :-)

Jeremy,

I seem to remember that you are using an NC - 2 Tamaya navigational calculator. If the LOP function on the NC -2 displays azimuths in degrees and minutes (like the NC-77) then the navigator can be tricked into misreading 000.55 on the display as half a degree instead of 000.92 degrees. I have made this mistake many times. My Palm program displays azimuths in degrees and tenths which I like better. This could be the source of your amplitude /azimuth discrepancy.
