Quick reference guide |
 |
| Course, Distance & Arrival Position |
|
| |
|
- δLat = difference in Latitude between the 2 points, N or S
- δLong = difference in Longitude between the 2 points, E or W
- θm = mid-Latitude
- θc = Course
- D = Distance
- p = Departure
COURSE
tan θc = cos θm x δLong
δLat
DISTANCE
Distance = 1
cos θc
ARRIVAL POSITION
Difference of Latitude = D x cos θc
Difference of Longitude = D x sin θc
cos θm
