The automatic flight control system (AFCS) in an aircraft is coupled to the guidance outputs from an inertial navigation system (INS) and the aircraft is flying from waypoint No. 2 (60°00'S 070°00'W) to No. 3 (60°00'S 080°00'W).Comparing the initial track (T) at 070°00'W and the final track (T) at 080°00'W, the difference between them is that the initial track is approximately:
