Celestial Navigation · Azimuth Angle
In Pub. No. 229, the tabulated azimuth angle Z must be converted to true azimuth Zn using rules based on:
- AHeight of eye and dip
- BThe equation of time
- CIndex error
- DLatitude (N/S) and whether LHA is greater or less than 180°✓ Correct
Explanation
Z is measured from the elevated pole; the conversion rules (e.g., in north latitude: if LHA > 180°, Zn = Z; if LHA < 180°, Zn = 360° − Z) give the true azimuth measured clockwise from north.
Authority: Pub. No. 229, conversion of Z to Zn
