Celestial Navigation · Sight Reduction — Assumed Latitude
When using Pub. 229 or 249, the assumed latitude chosen is:
- AThe whole degree of latitude nearest the DR✓ Correct
- BExactly the DR latitude to the tenth of a minute
- CAlways the equator
- DThe latitude of the observed body
Explanation
The tables are entered with whole degrees, so the assumed latitude is the integral degree nearest the DR, and the assumed longitude is picked to make LHA a whole degree. This lets the precomputed table values be used directly.
