The great circle track X - Y measured at x is 319° , and Y 325° Consider the following statements
319 = westerly track
The direction increases from X (319) to Y (325).
In Southern Hemisphere direction of a westerly great circle increases.
The difference = convergency = 325- 319 = 6
Conversion angle = 6/2 = 3
Rhumb line track = 319 + 3 = 322
Answer : D) Southern hemisphere, Rhumb line track is 322° .
*In Northern Hemisphere direction of a westerly great circle decreases.
In Northern Hemisphere direction of a easterly great circle increases.
In Southern Hemisphere direction of a easterly great circle decreases.
In Southern Hemisphere direction of a westerly great circle increases.
