This indicates we are dealing with a great circle which is not along the equator, nor along a meridian
- actually, bfisk first part right, second wrong. All that part of the question is telling you is that the route is NOT along the equator in which case rhumb and g circle are identical and you WOULD arrive at destination.
For Student ATP - the clue is there from 'unusualAtitude' - find yourself a globe and trace an imaginary line anywhere other than around the equator. Try maintaining the same angle of crossing of the meridians from, say London to N York. There's your answer.
