H.O 249 was designed for flight navigators where such precision is not needed or possible. The error band of observations taken in flight is about 7 NM and the accuracy of the derived fixes is about 10 NM so no actual increase in navigational accuracy is achieved by higher precision in the calculation.

Method in Pub.229 is covering interpolation for determining azimuth angle. While using Pub.249, we are making interpolation for the Hc, but not for the azimuth angle. Is there any reason for this? I solved some problems with interpolation and results are much closer with the formula method.
Thank you very much.
Thank you very much.
