Celestial Navigation · Sight Reduction
When reducing a sight with Pub. No. 229, the assumed position is chosen so that:
- AThe assumed latitude equals the declination
- BLHA is a whole degree and assumed latitude is the nearest whole degree✓ Correct
- CThe assumed longitude equals the DR longitude exactly
- DThe intercept is always zero
Explanation
Pub. 229 is entered with whole-degree arguments, so the assumed longitude is selected to make LHA an integer and the assumed latitude is the nearest whole degree to the DR. The tables then return Hc and azimuth angle Z.
