Celestial Navigation · Intercept Method — Away
You compute Hc = 18°55.0' and observe Ho = 18°40.0'. What is the intercept and direction?
- A15.0' Toward
- B15.0' Away✓ Correct
- C25.0' Away
- D35.0' Toward
Explanation
a = Ho − Hc = 18°40.0' − 18°55.0' = −15.0'. Ho is less than Hc, so the observer is farther from the body than the assumed position; the intercept is plotted 15.0' AWAY from the azimuth (Ho Less, Away).
