I would argue that the problem is not sufficiently well specified. Is TC=YYY merely the initial course for a Great Circle trip during which the course will generally vary as the trip progresses. Or is TC to remain constant for the whole trip, i.e. a rhumb line course? Or something else altogether? -- Mike Wescott Wescott_Mike@EMC.COM
