Convergence Flashcards
1
Q
Convergence =
A
Ch Long x Sin Mean Latitude
The higher the latitude, the greater the angle of convergence
The change in the great circle track number
The angle of inclination between any two meridians
2
Q
EC =
A
Ch Long x Sin Mean Latitude
EC: Earth Convergence
3
Q
Rhumb Line
A
A curved line which crosses meridians at the same angle
Concave towards the nearest pole
EQ side of a great circle
4
Q
Conversion Angle (CA)
A
CA = 1/2 x EC
CA = 1/2 x Ch Long x Sin Mean Lat
5
Q
Q: If A + B are the same latitude….
A
Rhumb Line = E/W …… 90 degrees or 270 degrees
