Video Not Working? Fix It Now

Practical Celestial Navigation course: Using the Sight Reduction tables to find the Calculated Altitude (Hc) and True Bearing or Azimuth Angle to the body (Zn). NOTE: I made an error at 20:43 of this video, noting the "d" value pulled from the tables as negative. It should be positive and I made an on-the-fly correction at 25:20. Sorry about that! 1) Homework Assumed Latitude: 11º N LHA: 077º Declination: N 21º 19.4' Enter the Sight Reduction tables and find Hc and Zn HC = 15º 58' ZN = 289º 2) Homework Assumed Latitude: 26º S LHA: 050º Declination: S 14º 19.2' Enter the Sight Reduction tables and find Hc and Zn HC = 41º 55' ZN = 274º FOR A FULL LIST OF COURSE EPISODES, PLEASE REFER TO EPISODE 1.
