Given that : A is 55N 00 E/W
B is 54N 10 E
If the great circle track from A to B is 100 (T), What is the true Rhumb line Track at A
a. 096
b. 107
c. 104
d. 100
Ans is C(104). Its in N. hemisphere, where GC is concave to EQ and RL is a st line. therefore A to B RL trk will be greater than GC trk. apply CA= 1/2 dlong* into Sin Mean lat. CA= 1/2 into 10 into Sin 54*30* = 4*. Ans is 100+4=104*.
hope that helps!!
