🔍 Key Concepts

• Great circle sailing formulas using latitude and longitude of two positions • Conversion of degrees and minutes to decimal degrees before using trigonometric functions • Relationship between initial great circle course and the longitudes/latitudes of departure and destination

💭 Think About

• How does the difference in longitude between the two positions affect the great circle track and the initial course direction? • Are both positions in the same hemisphere for latitude and longitude, and how does that influence whether the initial course is generally easterly or westerly, northerly or southerly? • After finding the central angle between the two points, how do you convert that angle into a distance in nautical miles on a great circle route?

✅ Before You Answer

• Convert both positions from degrees and minutes to decimal degrees before applying any formulas • Carefully determine the difference of longitude (DLo), paying attention to east and west longitudes • After computing the central angle (in degrees), multiply by 60 NM per degree to get distance, and check that your distance is consistent with the general scale of the problem (about an ocean crossing)
