Celestial Navigation · Line of Position — Azimuth Relationship
A celestial line of position is always drawn:
- AEast-west
- BAlong the body's azimuth
- CPerpendicular to the body's azimuth (Zn)✓ Correct
- DToward the nearest port
Explanation
The LOP is a short arc of the circle of equal altitude, drawn at right angles to the azimuth at the intercept point. The intercept is measured toward or away from the body along the azimuth; the LOP crosses that point perpendicular to the azimuth.
